 by a reconstructed Classical pronunciation, closer to an earlier Roman pronunciation, and with a more transparent relationship between spelling and pronunciation. By the mid-20th century, classroom use of the traditional pronunciation had all but ceased. The traditional pronunciation, however, survives in academic English vocabulary:
  • In general academic vocabulary: campus, syllabus, curriculum, diploma, alumnus
  • In specialized anatomical vocabulary: aorta, biceps, cranium, patella, sinus, vertebra, etc.
  • In astronomical nomenclature, including the names of planets, moons, asteroids, stars and constellations, such as Mars, Io, Ceres, Sirius, Ursa Major, nova, nebula
  • In a number of historical terms and names, particularly those associated with Roman culture and politics: augur, bacchanal, consul, fibula, lictor, prætor, toga, Augustus, Cæsar, Cicero, etc.
  • In legal terminology and phrases: alibi, alias, de jure, obiter dictum, sub judice, subpœna etc. In many cases Classical pronunciation is used, however.
  • In the specialized terminology of literary studies: codex, colophon, epitome, index, periphrasis, parenthesis, etc.
  • In some mathematical terms: calculus, parabola, hyperbola, isosceles, rhombus, vector, etc.
  • In medical terminology describing diseases, symptoms and treatments: anæsthesia, bacterium, coma, diarrhœa, lumbago, mucus, nausea, ophthalmia, rabies, tetanus, virus, rigor mortis etc.
  • In words and names from classical mythology: Achilles, Argus, Calliope, Gorgon, Myrmidon, Sphinx, etc.
  • In some religious terms: angelus, basilica, Magi, martyr, presbyter, etc.
  • In certain sporting terms: gymnasium, stadium, discus, pentathlon
  • In the taxonomic nomenclature of botany and zoology: phylum, genus, species, chrysanthemum, hibiscus, rhododendron, fœtus, larva, ovum, pupa, chamæleon, lemur, platypus
  • In a very large body of words used everyday: album, apex, area, asylum, axis, basis, bonus, camera, census, circus, dilemma, error, focus, genius, icon, insignia, junior, major, medium, murmur, onus, panacea, podium, sector, stamina, terminus, trivia; as well as such common phrases as et cetera, non sequitur, quid pro quo, status quo, vice versa, etc.

Overview

In most cases, the English pronunciation of Classical words and names is predictable from the orthography, as long as long and short vowels
Vowel length

s must be used if the pronunciation is to be unambiguous; for Greek, long versus short α, ι, υ must be distinguished, as they are in A Greek–English Lexicon. However, the conventions of biological nomenclature forbid the use of these diacritics, and in practice they are not found in astronomical names or in literature. Without this information, it may not be possible to ascertain the placement of stress
Stress (linguistics)

The term is also used for similar patterns of phonetic prominence inside syllables. The word accent is sometimes also used with this sense.The stress placed...

Note that the following rules are generalizations, and that many names have well established idiosyncratic pronunciations.

Stress placement

Latin stress is predictable. It falls on the penultimate syllable when that is "heavy

", and on the antepenultimate syllable when the penult is "light".

(In Greek stress is not predictable, but may it be ignored when pronouncing Greek borrowings, as they have been filtered through Latin and have acquired the stress patterns of Latin words.)

A syllable is "light" if it ends in a single short vowel. For example, a, ca, sca, scra are all light syllables for the purposes of Latin stress assignment.

Any other syllable is "heavy":
  • if it is closed (ended) by a consonant: an, can, scan, scran
  • if the vowel is long or a diphthong

The importance of marking long vowels can be illustrated with Ixion
Ixion
In Greek mythology, Ixion was king of the Lapiths, the most ancient tribe of Thessaly, and a son of Ares, or Leonteus, or Antion and Perimele, or the notorious evildoer Phlegyas, whose name connotes "fiery". Peirithoös was his son...

When more than a single consonant follows a vowel, the syllable is closed and therefore heavy. (A consonant

 is not the same thing as a letter. The letters x [ks] and z [dz] each count as two consonants, but th [θ], ch [k], and ph [f] count as one, as the pronunciations in brackets suggest.) The English letter j was originally an i, forming a diphthong with the preceding vowel, so it forces the stress just as æ, œ, z, and x do.

     as either cha-rik-lō or cha-ri-klō, so both kəˈrɪkloʊ kə-RIK-loh and /ˈkærɪkloʊ/ KARR-i-kloh are accepted pronunciations in English.

Secondary stress

If more than two syllables precede the stressed syllable, the same rules determine which is stressed. For example, in Cassiopeia
Cassiopeia
-Mythology:* Cassiopeia , a queen of Ethiopia and mother of Andromeda in Greek mythology.-Science:* Cassiopeia , a northern constellation representing the queen* Cassiopeia A, a supernova remnant in that constellation....

 (also Cassiopēa), syllabified cas-si-o-pei-a, the penult pei/pē contains a long vowel/diphthong and is therefore stressed. The second syllable preceding the stress, si, is light, so the stress must fall one syllable further back, on cas (which coincidentally happens to be a closed syllable and therefore heavy). Therefore the standard English pronunciation is ˌkæsi.ɵˈpiːə KAS-ee-o-PEE-ə. (Note however that this word has the additional irregular pronunciation of /ˌkæsiˈoʊpiːə/ KAS-ee-OH-pee-ə.)

Long and short vowels in English

Whether a vowel letter is pronounced "long" in English (/eɪ, iː, aɪ, oʊ, juː/ ay, ee, eye, oh, you) or "short" (/æ, ɛ, ɪ, ɒ, ʌ/ a, e, i, o, u) is unrelated to the length of the original Latin or Greek vowel. Instead it depends on position and stress. Generally, a vowel followed by more than one consonant is short in English, as in Hermippe
Hermippe
In Greek mythology, Hermippe was a daughter of Boeotus. She was married to Orchomenus, son of Zeus and the Danaid Isonoe, but had a son Minyas with Poseidon. Orchomenus became legal father of her son....

 hərˈmɪpiː hər-MIP-ee, except that final -es is always long, as in Pales

 /ˈpeɪliːz/ PAY-leez; while vowels with no following consonant is long.

However, when a vowel is followed by a single consonant (or by a cluster of p, t, c/k plus l, r) and then another vowel, it gets more complicated.

    In Greek mythology, Ganymede is a divine hero whose homeland was Troy. Homer describes Ganymede as the most beautiful of mortals. In the best-known myth, he is abducted by Zeus, in the form of an eagle, to serve as cup-bearer in Olympus. Some interpretations of the myth treat it as an allegory of...

  • Exception: A stressed non-high vowel (a, e, o) stays long before a single consonant (or cluster of p, t, c/k plus l, r) followed by an /iː/ ee sound (e, i, y) plus another vowel at the end of a word: Proteus
    Proteus
    In Greek mythology, Proteus is an early sea-god, one of several deities whom Homer calls the "Old Man of the Sea", whose name suggests the "first" , as protogonos is the "primordial" or the "firstborn".

     /dɨˈmiːtriəs/ di-MEE-tree-əs. This is because, historically and regionally, in many of these words the e, i, y is pronounced /j/ y and combines with the following syllable, so that the preceding syllable is penultimate and therefore open: /ˈproʊtjuːs/ PROH-tews.


Note that in many dialects a syllable followed by r tends to be closed regardless of position, and while the long/short distinction described above is maintained, the r has its own effect on the vowel, as in Elara
Elara
Elara may refer to one of the following:*Elara , a moon of Jupiter*Elara , the mother of Tityas in Greek mythology*Elara , an ancient Sri Lankan king...

 /iːˈlɛərə/ ee-LAIR (a long but closed syllable ending in r).

Alphabet

Anglo-Latin (hereafter A-L) includes all of the letters of the English alphabet except w, viz.: a b c d e f g h i j k l m n o p q r s t u v x y z. It differs from Classical Latin in distinguishing i from j and u from v.
In addition to these letters the digraphs æ and œ may also be used (as in Cæsar and phœnix). These two digraphs respectively represent mergers of the letters ae and oe and are often written that way (e.g. Caesar, phoenix). However, since both ae and oe represent a simple vowel, not a diphthong, in A-L, the use of the single letters æ and œ better represents the reality of A-L pronunciation.
Despite being written with two letters, the sequences ch, ph, rh, th represent single sounds. The letter x, on the other hand, usually behaves like a sequence of two sounds (being equivalent to cs).

Conversion of Greek to Latin

A-L includes a large amount of Greek vocabulary; in principle, any Greek noun or adjective can be converted into an A-L word. There is a conventional set of equivalents between the letters of the Greek and Roman alphabets, which differs in some respects from the current mode of Romanizing Greek. This is laid out in the tables below:
Vowels Diphthongs
Greek letter α ε η ι ο υ ω αι ει οι υι αυ ευ ου
Romanization a e ē i o u ō ai ei oi ui au eu ou
Conversion to Latin a e e i o y o æ i œ yi au eu u

Romanization h b g gg gk gch d z th k l m n x p r rr s t ph ch ps
Conversion to Latin h b g ng nc nch d z th c l m n x p r
rh
rrh s t ph ch ps


Rh is used for Greek ρ at the beginnings of words, e.g. ρομβος (rombos) > rhombus.
Rarely (and mostly in words relatively recently adapted from Greek), k is used to represent Greek κ. In such cases it is always pronounced [k] and never [s] (as it might be if spelled c) : e.g. σκελετον skeleton, not "sceleton".

Greek accent marks and breath marks, other than the "rough breathing" (first in the list of consonants above), are entirely disregarded; the Greek pitch accent is superseded by a Latin stress accent, which is described below.

Frequently, but not universally, certain Greek nominative endings are changed to Latin ones that cannot be predicted from the tables above. Occasionally forms with both endings are found in A-L, for instance Latinized hyperbola next to Greek hyperbole. The most usual equations are found below:

Examples:
  • Greek αγγελος (aggelos) > Latin angelus (γγ > ng, -ος > us)
  • Greek ελλειψις (elleipsis) > Latin ellipsis (ει > i, ψ > ps)
  • Greek μουσειον (mouseion) > Latin museum (ου > u, ει > e, -ον > um)
  • Greek μαιανδρος (maiandros) > Latin mæander (αι > æ, -ρος > er)
  • Greek χρυσανθεμον (chrusanthemon) > Latin chrysanthemum (χ > ch, υ > y, θ > th, -ον > um)
  • Greek διαρροια (diarroia) > Latin diarrhœa (ρρ > rrh, οι > œ)

Letters and sounds

  • The letters b, f, k, l, m, p, v and z have each only one sound, which corresponds to the equivalent IPA symbols /b f k l m p v z/.
  • The letter j has the single sound /dʒ/.
  • The letter r has a single sound, /r/ in rhotic
    Rhotic and non-rhotic accents
    English pronunciation can be divided into two main accent groups: a rhotic speaker pronounces a rhotic consonant in words like hard; a non-rhotic speaker does not...

     dialects of English. In non-rhotic dialects, it varies according to placement in a syllable. At the beginning of a syllable, it is pronounced /r/. At the end of a syllable, i.e. between a vowel and a consonant, or after a vowel at the end of a word, it is dropped—though not without, frequently, affecting the pronunciation of the previous vowel sound. If r occurs at the end of a word after a vowel, and the next word begins with a vowel, it is usually pronounced as the beginning of the first syllable of the next word. Rh and rrh are pronounced exactly like r and rr.
  • When followed by a vowel, the combinations qu (always) and gu and su (usually) stand for /kw/, /ɡw/, and /sw/ respectively.
  • The combination ph is pronounced /f/.
  • The combination th is pronounced /θ/.
  • The combination ch is pronounced /k/ in all environments.
  • The letters c, d, g, h, n, s, t, x have different values depending upon surrounding sounds and syllable structure.

Phonemes

The underlying consonantal phonemes of A-L are close in most respects to those of Latin, the primary difference being that /w/ and /j/ are replaced in A-L by /v/ v and /dʒ/ j. The sounds /θ/ th and /x/ ch were borrowed from Greek; the latter became an invariable /k/ subsequent to the split of original /k/ c into /k/ and /s/.

Greek consonant clusters

Several word-initial clusters, almost all derived from Greek, are simplified in A-L by omitting the first consonant:
  • βδ bd becomes /d/: bdellium
  • τμ tm becomes /m/: tmesis
  • κν cn, γν gn, μν mn and πν pn become /n/: Cnossus, gnosis, Mnemosyne, pneumonia
  • ψ ps becomes /s/: psyche
  • κτ ct and πτ pt become /t/: Ctesiphon, ptosis
  • χθ chth and φθ phth become /θ/: Chthon, phthisis
  • ξ x becomes /z/: Xanthippe


In the middle of words both consonants in these clusters are pronounced (e.g. Charybdis, Patmos, Procne, prognosis, amnesia, apnœa, synopsis, cactus, captor); medial chth and phth are pronounced /kθ/ and /fθ/ respectively, as in autochthon and naphtha.

Polyphony

Miscellaneous environments

Environments that condition the appearance of some of these phonemes are listed below:
Sound affected Spelling Environment Resulting sound Examples
/h/ h between a preceding stressed and a following unstressed vowel cf. "vehement, annihilate"
after x exhibitor
/n/ n before velars /k/ (c, ch, k, q) and /ɡ/ g /ŋ/ incubator, fungus
/s/ s between two vowels /z/ miser, Cæsar, Jesus
between a vowel and a voiced consonant plasma, presbyter
after a voiced consonant at the end of a word lens, Mars
/ks/ x initially /z/ Xanthippe
in the prefix ex- before a vowel or (silent) h in a stressed syllable /ɡz/ exemplar, exhibitor


The change of intervocalic /s/ to /z/ is common but not universal. Voicing is more common in Latin than in Greek words, and never occurs in the common Greek ending -sis, where s is always voiceless: basis, crisis, genesis.
Palatalization

The most common type of phonemic change in A-L is palatalization
Palatalization
In linguistics, palatalization , also palatization, may refer to two different processes by which a sound, usually a consonant, comes to be produced with the tongue in a position in the mouth near the palate....

. A-L reflects the results of no less than four palatalization processes. The first of these occurred in Late Latin
Late Latin
Late Latin is the scholarly name for the written Latin of Late Antiquity. The English dictionary definition of Late Latin dates this period from the 3rd to the 6th centuries AD extending in Spain to the 7th. This somewhat ambiguously defined period fits between Classical Latin and Medieval Latin...

, the second in Proto-Gallo-Romance, the third and fourth within the history of English. While the first two palatalizations are universally used in variants of A-L, the third and especially the fourth are incompletely observed in different varieties of A-L, leading to some variant pronunciations.
  • Palatalization 1 affected only the sound of t, converting it to /ts/ when it preceded a semivowel i (at that stage pronounced /j/) and did not follow s, t, or x. This /ts/ sound eventually merged with /s/ and was subject to further changes in Palatalization 3. When /t/ followed /s/ or /t/ it did not change; in some cases it might later change to /tʃ/ by Palatalization 4. Note that t did not change to /s/ before semivowel e, but remained /t/ as in confiteor.
  • Palatalization 2 affected the sounds of c and g, converting them to /ts/ and /dʒ/; the /ts/ arising from c merged with the /ts/ arising from t, and both shared further developments of this sound, turning to /s/. When geminate (double), palatalized cc and gg were affected diversely; only the second c in cc was palatalized, producing the sound /ks/, as in successor; but both gs in gg were palatalized, producing a /dʒ/ sound, as in "exaggerate".
  • Palatalization 3 affected /s/ and /z/ of whatever origin, changing them to /ʃ/ and /ʒ/.
  • Palatalization 4 affected /s/ and /z/ exactly as Palatalization 3 did, but also affected /t/ and /d/, changing them to /tʃ/ and /dʒ/


Some of the occasions on which palatalizations 3 and 4 fail to take effect should be noted:
  • Palatalization 3 fails: asphyxia, Cassiopeia, dyspepsia, excelsior, exeunt, gymnasium, symposium, trapezium. Note that the semivowel i is always pronounced as a full vowel /i/ in these cases. In some dialects Palatalization 3 frequently fails when another /ʃ/ sound follows, as in "enunciation", "pronunciation", "appreciation", "glaciation", "association", with the /s/ sound then generalized to closely related forms ("enunciate", "appreciate", "associate").
  • Palatalization 4 fails (in some dialects): cæsura, fistula, pæninsula, pendulum.


Summary

1 /t/ t when not initial, following s, t, or x, and before the semivowel i /s/ annunciator (from annuntiator)

/t/ t /tʃ/ spatula
/z/ s /ʒ/ cf. "usual"


See further the section on the "semivowel" below.
Degemination

Following all of the above sound changes except palatalizations 3 and 4, "geminate" sequences of two identical sounds (often but not always double letters) were degeminated, or simplified to a single sound. That is, bb, dd, ff, ll, mm, nn, pp, rr, ss, tt became pronounced /b d f l m n p r s t/. However, for the purposes of determining whether a syllable is open or closed
Openness
Openness is the quality of being open. It sometimes refers to a very general philosophical position from which some individuals and organizations operate, often highlighted by a decision-making process recognizing communal management by distributed stakeholders rather than a centralized authority...

, these single consonants continue to act as consonant clusters.

Other notable instances involving degemination include:
  • cc developed two pronunciations:
    • before a front vowel (e, æ, œ, i, y) cc is pronounced /ks/, and as it consists of two distinct sounds, is not degeminated.
    • before a back vowel (a, o, u) cc was pronounced /kk/ which degeminated to simply /k/
  • cqu /kkw/ degeminated to /kw/
  • gg also has two pronunciations:
    • before a front vowel, gg is pronounced /dʒ/ after degemination.
    • before a back vowel, gg is pronounced /ɡ/ after degemination.
  • sc before a front vowel was pronounced /ss/, and degeminated to /s/.
  • sc and ss before the "semivowel" are pronounced /ʃ/


The following combinations, derived from Greek, are also pronounced as single consonants:
  • κχ cch is pronounced /k/: Bacchus
  • πφ pph is pronounced /f/: Sappho
  • τθ tth is pronounced /θ/: Pittheus

Syllables

The simple vowels of A-L (
a, æ, e, ei, i, o, œ, u, y) can each have several phonetic values dependent upon their stress, position in the word, and syllable structure. Knowing which value to use requires an explanation of two syllabic characteristics, openness and stress.

Openness

Openness is a quality of syllables, which may be either open, semi-open, semi-closed, or fully closed.

Fully closed syllables

Fully closed syllables are those in which the vowel in the middle of the syllable (the vocalic nucleus) is followed by at least one consonant, which ends or "closes" the syllable. Vowels in fully closed syllables appear:
  • At the end of a word followed by at least one consonant, e.g. plus, crux, lynx.
  • In the middle of a word followed by two or more consonants. The first of these consonants "closes" the syllable, and the second begins the following syllable; thus a word like lector consists of the two closed syllables lec and tor. Sequences of three or more consonants may be broken up in different ways (e.g. sanc.tum, sculp.tor, ul.tra, ful.crum, ex.tra) but nothing depends upon the exact way in which this is done; any sequence of three or more consonants creates a closed syllable before it. The letter x is equivalent to cs, and as such also closes a syllable; a word like nexus is syllabified nec.sus, and consists of two closed syllables.
  • Two successive consonants of identical pronunciation are always pronounced as a single consonant in A-L. When such a consonant sequence follows a penult syllable, the syllable counts as closed for the purposes of determining the position of stress: ba.cíl.lus, di.lém.ma, an.tén.na, co.lós.sus; they also prevent a penult syllable from lengthening, as in the previous examples and also pal.lor, com.ma, man.na, cir.rus, cas.si.a, pas.sim, glot.tis. They also count as closed for the purpose of determining whether a u is open or closed. In these respects they act precisely like syllable-closing consonant sequences, although they are pronounced as single sounds. (In words like successor the two cs do not merge, because each of them has a different sound – /k/ and /s/, respectively.)
  • Certain sequences of consonants do not close syllables: these include all instances of obstruents (stops and fricatives) followed by r, including br, cr, chr, dr, gr, pr, tr, thr. Thus words like supra and matrix are syllabified as su.pra and ma.trix, and the first syllable of both words is open; likewise a.cro.po.lis, di.plo.ma, de.tri.tus. The sequence /kw/ (spelled qu) also does not close the preceding syllable; i.e., one syllabifies re.qui.em and not req.ui.em.
  • Sequences of obstruents followed by l are less consistent. The sequences cl, chl, gl and pl do not close a syllable, e.g. nu.cle.us, du.plex with open first syllables; but the sequences bl, tl, thl do close a syllable, producing the syllabifications Pub.li.us, at.las, pen.tath.lon, with closed syllables before the l.

Semi-closed syllables

Semi-closed syllables are formerly closed, unstressed syllables that became open due to the merger of two following consonants of the same sound. For the purpose of determining vowel reduction in initial unstressed syllables they count as open.
  • Double consonants following an initial syllable containing a, e, i, o merge to count as one consonant: a.(c)cumulator, a.(g)gres.sor, ca.(l)li.o.pe, a.(p)pen.dix, e.(l)lip.sis, co.(l)lec.tor, o.(p)pres.sor, o.(p)pro.bri.um. The first syllables of all these words are only partially closed, and the vowels are reduced.
  • The same phenomenon occurs after u, but note that the u is both closed and reduced: su.(p)pres.sor, su.(c)ces.sor, cu.(r)ri.cu.lum.

Semi-open syllables

Semi-open syllables are formerly closed, unstressed syllables that are followed by a sequence of consonants that can stand at the beginning of a syllable. Since instances of obstruents+r or l are already considered open, semi-open syllables are practically restricted to instances of s+obstruent, bl, and in some cases perhaps tl. Vowels in initial semi-open syllables may be treated as open for all purposes except for determining the value of u, which is still closed in semi-open syllables.
  • When s is followed by a consonant, s syllabifies with the following consonant: a.spa.ra.gus, pro.spec.tus, na.stur.ti.um, a.sphyc.si.a (asphyxia). S also syllabifies with a following palatalized c : a.sce.sis, pro.sce.ni.um. When s syllabifies with a following consonant, the preceding syllable counts as semi-open. Possible exceptions are pos.te.ri.or, tes.ta.tor.
  • Other sequences of consonants fully close an initial unstressed syllable and produce a short vowel: an.ten.na, am.ne.si.a, bac.te.ri.um, mag.ni.fi.cat, mac.sil.la (maxilla), spec.ta.tor, per.so.na, oph.thal.mi.a, tor.pe.do.


See further the section on initial unstressed syllables below.

Open syllables

Open syllables are those in which the nucleus is followed:
  • By no consonant at the end of the word: pro, qua.
  • By a vowel in the middle of a word : oph.thal.mi.a, fi.at, cor.ne.a, cha.os, chi.as.mus, a.ma.nu.en.sis.
  • By only a single consonant in the middle of a word: sta.men, æ.ther, hy.phen, phœ.nix, ter.mi.nus, a.pos.tro.phe.
  • By those consonant clusters that do not fully or partially close a syllable In the middle of a word : ma.cron, du.plex, Cy.clops, tes.ta.trix, a.cro.po.lis.

Primary stress

Stress is another characteristic of syllables. In A-L, it is marked by greater tension, higher pitch, lengthening of vowel, and (in certain cases) changes in vowel quality. Its exact concomitants in Classical Latin are uncertain. In Classical Latin the main, or primary stress is predictable, with a few exceptions, based on the following criteria:
  • In words of one syllable, stress falls on that syllable, as marked in the following syllables with an acute accent: quá, nón, pár.
  • In words of two syllables, stress falls on the first syllable of the word (the penult, or second from the end): e.g. bó.nus, cír.cus.
  • In words of three or more syllables, stress falls either on the penult or the antepenult (third from the end), according to these criteria:
    • If the penult contains a short vowel in an open syllable, the stress falls on the antepenult: e.g. stá.mi.na, hy.pó.the.sis.
    • If the penult contains a long vowel; a diphthong; a closed syllable (with any length of vowel); or is followed by z, the stress falls on the penult.
      • Long vowel:
      • Diphthong:
      • Closed syllable:
      • z: horízon

Primary stress can therefore be determined in cases where the penult is either closed or contains a diphthong. When it contains a vowel that may have been either short or long in Classical Latin, stress is ambiguous. Since A-L does not distinguish short from long vowels, stress becomes a lexical property of certain words and affixes. The fact that
decorum is stressed on the penult, and exodus on the antepenult, is a fact about each of these words that must be memorized separately (unless one is already familiar with the Classical quantities, and in the former case, additionally with the fact that decus -ŏris n. with short -o- syllable became in late Latin decus/decor -ōris m. with long -o- syllable: 'Dómine, diléxi decórem domus tuæ').

Secondary stress

Secondary stress is dependent upon the placement of the primary stress. It only appears in words of four or more syllables. There may be more than one secondary stress in a word; however, stressed syllables may not be adjacent to each other, so there is always at least one unstressed syllable between the secondary and primary stress. Syllables containing semivowel e or i are never stressed.
  • If a 4-syllable word has primary stress on the antepenult, there is no secondary stress: pa.rá.bo.la, me.tá.the.sis.
  • If a 4-syllable word has primary stress on the penult, secondary stress is on the first syllable, marked hereafter with a grave accent: à.la.bás.ter, è.pi.dér.mis, sì.mu.lá.crum, prò.pa.gán.da, ùl.ti.má.tum.
  • If a 5-syllable word has primary stress on the antepenult, secondary stress is on the first syllable: hìp.po.pó.ta.mus, Sà.git.tá.ri.us, Phì.la.dél.phi.a.


Secondary stress in words with three or more syllables before the primary stress is less predictable. Such words include those of five syllables with penult primary stress, and all words of six syllables in length or longer. The following generalizations about such long words may be made:
  • The syllable immediately before the primary stress is never stressed.
  • Words produced by derivation from a shorter word convert the primary (and, if any, secondary) stress of the stem into a secondary stress, as long as it does not fall immediately before the new primary stress: é.le.phant- + í.a.sis becomes è.le.phan.tí.a.sis
  • Compounds of which the compound element consists of more than one syllable likewise convert the primary stress of their elements into secondary stress: phár.ma.co- + póei.a becomes phàr.ma.co.póei.a.
  • If a primary stress is eliminated in compounding or derivation because it would stand next to another stress, secondary stress remains unchanged: pùsillánimus + itas becomes pùsillanímitas.
  • Single-syllable prefixes and single-syllable compound-elements are generally unstressed: ac.cù.mu.lá.tor, im.pè.di.mén.ta, Her.mà.phro.dí.tus
  • In other cases where the composition of the word may be unclear, every other syllable before the primary stress may be stressed: a.mà.nu.én.sis, ò.no.mà.to.póei.a. In some cases the third syllable before the primary stress is stressed when the second syllable is light, just as when assigning the primary stress.

Unstress

Unstressed syllables are all others. They are always adjacent to a stressed syllable; that is, there can never be more than two unstressed syllables in a row, and that only when the first one follows a stressed syllable.

Semivowel

Several sound-changes in A-L are due to the presence of the "semivowel", an alteration of certain front vowels. Originally ordinary vowels, they acquired at different points in history the value of the glide /j/ (a y-sound like that in English canyon). Subsequently, their value has fluctuated through history between a consonant and a vowel; the term "semivowel" thus reflects the intermediate historical as well as phonetic position of this sound. The environment in which the semivowel was produced was as follows:
  1. The vowel was e (æ, œ), i (ei), or y.
  2. The vowel came immediately before a vowel or diphthong.
  3. The vowel was not in the initial syllable: e, æ, ei, i and y in rhea, mæander, meiosis, fiat, diaspora, hyæna, did not become semivowels.
  4. The vowel was unstressed: e, æ, œ, ei, i in idea, Piræus, diarrhœa, Cassiopeia, calliope, elephantiasis did not become semivowels.


Examples of words where
e, i, y became semivowels include: miscellanea, chamæleon, nausea, geranium, rabies, Aries, acacia, ratio, fascia, inertia, halcyon, polyanthus, semiosis, mediator, Æthiopia, Ecclesiastes.

The effects of the semivowel include the following:
  1. Though always in hiatus with a following vowel, semivowel i and y are never pronounced like long i or y (e.g. /aɪ/); historically semivowel e could also be distinguished from "long e" (formerly [ɛː] or [eː]). In current varieties of A-L, semivowels are pronounced in a variety of ways:
    • Most frequently as /i/: labia, radius, azalea, præmium, cornea, opium, Philadelphia, requiem, area, excelsior, symposium, Cynthia, trivia, trapezium. In British Received Pronunciation, the prescribed pronunciation was once /ɪ/.
    • In some dialects or registers of English as /j/, e.g. junior pronounced [ˈdʒuːnjər].
    • Merged with a following -es or -e ending, as in Aries, scabies .
    • They are usually deleted following the palatals /ʃ/, /ʒ/, and /dʒ/: Patricia, consortium, Persia, nausea, ambrosia, Belgium.
    • Occasionally a semivowel is retained after a palatal sound: ratio, sometimes Elysium. This type of pronunciation is an artificiality, as the sounds /ʃ/ and /ʒ/ resulted from an absorption of the original /j/ in the sequences /sj/, /zj/. The pronunciations with /ʃi/ and /ʒi/ result from a re-introduction of the i sound to conform with the spelling. This pronunciation was, however, recommended by academics, and as such is common in the pronunciation of A-L phrases such as ab initio, in absentia, venire facias.
  2. The consonant t changed to /s/ and then to /ʃ/ before the semivowel arising from i: minutia, inertia, nasturtium.
  3. The sibilants /s/ (including ss, sc, c, and t) and /z/ (usually spelled s) are usually palatalized before the semivowel:
    • /s/ > /ʃ/: cassia, fascia, species, militia
    • /z/ > /ʒ/: amnesia, ambrosia
  4. The vowels a, e, æ, and o in an open antepenult syllable become long if a semivowel appears in the next syllable:
    • radius, Asia, azalea,area
    • anæmia, chamæleon
    • genius, medium, interior
    • odium, cochlea, victoria
This lengthening takes place regularly in antepenultimate syllables. It is less regular in syllables further back. On the one hand, there are words that do seem to lengthen before a semivowel in the next syllable:
  • Æthiopia, Ecclesiastes, mediator, negotiator, variorum.
On the other hand, some words have short vowels:
  • gladiator, apotheosis, Meleagrus, polyanthus (and other words containing poly- followed by a vowel).
In general, those words with lengthened vowels in pre-antepenult syllables before a semivowel in the next syllable are those that are derive from a word with a regularly lengthened vowel in an antepenult syllable, e.g., Æthiopia from Æthiops ("Ethiopian"), Ecclesiastes from ecclesia ("church"), mediator from medium, negotiator from negotium ("business'), variorum from varius ("manifold"). The failure of gladiator (from gladius, "sword") to have a long vowel is anomalous.

Mergers

The most notable distinction between A-L and other varieties of Latin is in the treatment of the vowels. In A-L, all original distinctions between long and short vowels have been obliterated; there is no distinction between the treatment of a and ā, etc., for instance. However, the subsequent development of the vowels depended to a large degree upon Latin word stress (which was preserved nearly unchanged in the mediæval period), and as this was in part dependent upon vowel length, in certain cases Latin vowel length contrasts have been preserved as contrasts in both stress and quality. However, the immediate governing factor is not length but stress: short vowels that were stressed for various reasons are treated exactly like stressed long vowels.

In addition to the merger of long and short vowels, other vowel mergers took place:
  • the diphthongs æ and œ merged with e
  • the vowels i and y merged
  • the diphthong ei (also æi, œi), when still written distinctively, in pronunciation was merged with i or (more frequently) e


The merger of
æ and œ with e was commonly recognized in writing. Sometimes forms written with æ and œ coexist with forms with e; in other cases the form with e has superseded the diphthong in A-L. Consider the following:
  • æon and eon, æther and ether, amœba and ameba, anæmia and anemia, anæsthesia and anesthesia, cæsura and cesura, chamæleon and chameleon, dæmon and demon, diæresis and dieresis, encyclopædia and encyclopedia, fæces and feces, fœtus and fetus, hyæna and hyena, prætor and pretor

The following words are usually spelled with
e, though they originally had æ:
  • ænigma > enigma, æquilibrium > equilibrium, æra > era, Æthiopia > Ethiopia, diarrhœa > diarrhea, mæander > meander, musæum > museum, œsophagus > esophagus, pæninsula > peninsula, præcentor > precentor, prædecessor > predecessor, præmium > premium, præsidium > presidium, tædium > tedium


In other cases, particularly names, the forms with the diphthongs are the only correct spelling, e.g.
ægis, Cæsar, Crœsus, Œdipus, onomatopœia, pharmacopœia, Phœbe, phœnix, Piræus, sub pœna.

The sequences
ei, æi, œi (distinguished in writing and pronunciation from ej, the vowel followed by a consonant, as in Sejanus) are sometimes retained in spelling preceding a vowel. In such cases the sequence is invariably pronounced as a simple vowel, sometimes i (as in meiosis, pronounced as if miosis) but more usually e: Cassiopeia, Deianira, Pleiades, onomatopœia, pronounced as if Cassiopea, Deanira, Pleades, onomatopea.

The result was a system of five vowels,
a, e, i, o, u. These would subsequently split, according to their environment, into long, short, and (eventually) unstressed variants; and these variants would eventually also be altered in various dialects of A-L dependent upon neighboring sounds. However, in phonemic terms, A-L still has only five vowels, with multiple allophones.

In addition, there were the diphthongs,
ai, oi, ui, au and eu. Of these, ai and au eventually monophthongized, eu merged with the open variant of u, and yi merged with the "long" i. Only oi and ui remained as true diphthongs, but both are extremely rare.

Realizations of a, e, i and o

The vowels a, e, i, o have three primary phonemes: long, short, and reduced; each of these may, in turn, have allophonic variations based on their phonetic environment, including whether they are stressed; in an open or closed syllable; their position in the word; and neighboring consonants. One of the most common environmental alterations of a vowel is due to the presence of a following r. Such vowels are called "r-colored".

Short vowels

This is the default value for vowels, observed:
  1. In closed monosyllables
  2. In stressed closed penult syllables
  3. In all antepenult syllables, open or closed, which receive primary stress, except for those lengthened due to a following semivowel
  4. In all syllables with secondary stress
  5. In fully closed unstressed syllables which immediately precede, but do not follow, a primary or secondary stress (usually in the first syllable of a word), with exceptions for certain prefixes


All short vowels have variants colored by a following
r sound when the r is followed by a different consonant (not r) or by the end of the word. In addition, a there is a variant of short a that only appears after a /w/ sound – chiefly found in the sound qu /kw/.

Exceptionally, monosyllables ending in
es are pronounced with the rhyme /iːz/, e.g. pes, res. This pronunciation is borrowed from that of -es used as an ending.

Exceptions to the pronunciation of short
y generally involve prefixed elements beginning with hy- in an open syllable, such as hydro- and hypo-; these are always pronounced with a long y, e.g. hydrophobia, hypochondria. This pronunciation is the result of hypercorrection; formerly they were pronounced with a short /ɪ/, as is still the case in the word "hypocrite" and (for some speakers and formerly commonly) hypochondria.

Prefixes may also behave in anomalous ways:
  1. The prefix ob- in unstressed syllables may be reduced to /əb/, even when it closes a syllable: cf. "obsession, oblivion".
  2. The Greek prefix en-, em- in a closed unstressed syllable may be reduced to /ɨn/, /ɨm/: encomium, emporium.
  3. The prefix ex- in an unstressed syllable may be reduced to /əks/, /əɡz/, despite always being in a closed syllable: exterior, exemplar.
  4. The prefix con-. com- is reduced to /kən/, /kəm/ when unstressed: consensus, compendium, regardless of whether the syllable is closed or not.
  5. The preposition and prefix post(-) is anomalously pronounced with "long o": /poʊst/: post-mortem and cf. "postpone"; also thus in words in which post was originally a preposition (postea, postquam) but not in other derivatives, being pronounced with short o in posterus, posterior, postremo, postridie.

Long vowels

Long vowels are those that historically were lengthened. By virtue of subsequent sound changes, most of these are now diphthongs, and none is distinguished by vowel length—;however, the term "long" for these vowels is traditional. "Long" vowels appear in three types of environments:
  1. a, e, i and o are long in an open monosyllable
  2. a, e, i and o are long in a stressed open penult syllable
  3. a, e and o are long when in an open syllable followed by semivocalic i and e
  4. a and o are long when they precede another vowel in hiatus; i and e are long in the same environments, but only when they are not semivocalic (i.e., when they are in the initial syllable or receive primary stress). Hiatus may be original, or may arise from the deletion of h between a stressed and unstressed syllable

Reduced vowels

Reduced vowels appear in unstressed syllables, except for:
  • Closed initial unstressed syllables, which are generally short.
  • Certain unstressed final syllables.

Initial unstressed syllables

A variety of possible realizations are available for open, semi-open, and semi-closed initial unstressed syllables, including (for e and i) long, short, and reduced variants. Fully closed initial unstressed syllables are always short.

The variation in the value of the initial open unstressed vowel is old. Two different types of variation can be distinguished; the older use of a "long" vowel for i, y, o (and their variants); and more recent variations in the value of the reduced vowel.

No completely general rule can be laid down for the appearance of an initial unstressed long vowel, although such vowels must have appeared before the shortening of geminate consonants, as they are restricted to fully open syllables. The most general tendency is for long vowels to appear when i and y are either preceded by no consonant or by h, e.g. idea, isosceles, hyperbola, hypothesis. The prefixes in and syn never have long vowels: inertia, synopsis. I and y also tend to be short when the next syllable contains an i or y, short or long: militia, divisor.

O is a little less likely to appear with a long value in this location; or, at any rate, it is harder to distinguish the long value from the reduced vowel.

Unstressed e and i in open syllables had merged by the early 17th century; their reduced reflex is often transcribed [ə], but by many speakers is still pronounced as a high front lax vowel, distinct from the [ə] derived from a. For such speakers, the first syllables in Demeter and Damascus are pronounced differently. The sound is not identical to the short vowel [ɪ], but is more central: [ɪ̈], and here transcribed as /ɨ/

Unstressed o, also often transcribed [ə], is by many speakers pronounced with considerable lip-rounding: [ɞ], here transcribed /ɵ/.
Semi-closed initial

o /ə/ ɔ ə ə ə collector, oppressor, opprobrium, possessor


The partially closed initial unstressed vowels began as short vowels, but were later reduced.

These are the same sounds as in the preceding chart, but without the option of the "long" vowels and much less rounding of the
o.

proscenium does not fall in this group, apparently because felt to be pro+scenium.
Medial unstressed syllables

All vowels in medial unstressed syllables are reduced to /ə/ or /ɨ/, regardless of whether they are in open or closed syllables.
Medial unstressed vowels American British Australian Examples

y /ə/ ə ɪ, ə ə platypus, analysis, apocrypha
Vr /ər/ ɚ ə ə interceptor, superficies

Open and closed u

The pronunciation of the letter u does not depend upon stress, but rather upon whether the syllable in which it appears is open or closed. There are no "long" and "short" variants of either type of u, but there are reduced and r-colored variants of both types.

Open u

The underlying sound of open u is /juː/; it shares developments with the homophonous diphthong eu, which can however appear in closed syllables.

The sound [j] in /juː/ and its variants is deleted in various environments:
  • After palatal consonants (/ʃ tʃ ʒ dʒ/), whether original or resulting from the merger of /j/ and the preceding consonant, in both stressed and unstressed syllables; e.g. /dʒ/: junior, Julius, Jupiter, cæsura, educator, spatula, fistula


After the following consonants when they precede
u in an initial, final, or stressed syllable: and /l/: rumor, verruca, luna, Lucretia, Pluto, effluvium, /z/, and /st/: super, superior, Vesuvius, Zeus, stupor

In some dialects, particularly of American English, /j/ is deleted after the following consonants when they precede
u in an initial, final or stressed syllable:, /n/, /t/ and /θ/: duplex, caduceus, medusa, nucleus, lanugo, tutor, Thucydides
  • For some speakers, /juː/ is pronounced [ɪu] following these consonants.


/j/ is not deleted in the following environments:
  • When u is the first letter of the word or follows /h/: uterus, humerus
  • Following a vowel: Ophiuchus
  • Following labials /p b f v m/: pupa, furor, nebula, uvula, musæum
  • Following velars /k ɡ/ : cumulus, lacuna, Liguria
  • When it is in an interior unstressed syllable not following a palatal consonant, /j/ remains after a single consonant even when it might be deleted in a stressed syllable: amanuensis and cf. "cellular, granular", for some speakers "virulent".
  • After a consonant cluster /j/ may or may not be deleted: pæninsula, cornucopia


Unstressed open u may retain rounding in some positions for some speakers, varying between [ʊ] and [ə] ([jʊ] and [jə]). It is here transcribed /ʉ/ or /jʉ/.
Open u
Environment Examples with /j/ Examples without /j/
/juː/ in stressed syllables jɵu humor, uterus, tribunal, euthanasia ɵu rumor, verruca, junior, Jupiter
/jʊər/ in stressed syllables, r-colored furor ɵ juror
/jʉ/ in unstressed initial syllables musæum, urethra, euphoria, eureka ɵ superior
/jʉ/ in medial unstressed syllables jɵ, jə calculus, nebula ɵ, ə spatula
/juː/ in unstressed final syllables jɵu ɵu impromptu, situ, passu
/jʉ/ in unstressed hiatus jɵw, jəw amanuensis, innuendo

Closed u

Closed u appears only in closed syllables, except for instances of the prefix sub- before a vowel. It has reduced and r-colored variants, as shown below. r-coloration only appears when the r is followed by a different consonant (not r) or the end of the word.
Closed u

Diphthongs

Diphthongs in A-L are distinguished from simple vowels by having no long or short variants, regardless of position or syllable type. The only diphthongs that are at all common are au and eu. For variations in the pronunciation of the latter, see Open u. Au is, rarely, reduced in an unstressed syllable to [ə]: Augustus pronounced as if "Agustus". Such words may be pronounced with the full value of the diphthong, however.
Diphthongs American British Australian Examples
ai /eɪ/ ei æɪ Achaia, Maia, Gaius
au /ɔː/ ɒ ɔ o aura, pauper, nausea, autochthon, aurora, glaucoma, mausoleum
eu /juː/ ju, u ju neuter, euthanasia, zeugma
oi /ɔɪ/ ɔi ɔɪ coitus, paranoia
ui /(j)uː.j/* (j)ui (j)uɪ (j)uɪ alleluia, cuius
yi /aɪ/ ai ɑe harpyia


Note that ui is generally disyllabic, as in fruc.tu.i, va.cu.i, tu.i. The monosyllabic words cui and huic were traditionally pronounced /kaɪ/ and /haɪk/.

Endings

The pronunciation of the final syllables of polysyllabic words do not always correspond to what might be expected from the constituent phonemes. Some endings also have more than one pronunciation, depending upon the degree of stress given to the ending.

Three types of endings can be distinguished:

Vowel alone

The first class consists of vowels alone, i.e. -a, -e, -æ, -i, -o, -u, -y. In this class, the vowels are generally long, but -a is always /ə/.
Letter American British Australian Examples
a /ə/ ə ə ə circa, fauna, mania, quota
e /i, iː/ i ɪ i ante, epitome, posse, simile
æ /i/ algæ, larvæ, vertebræ
i, y /aɪ/ ai ɑe alibi, Gemini, moly
o /oʊ/ ɞu əu əʉ ego, Pluto, torpedo
u /juː/ (j)u ju (in) situ


In British Received Pronunciation, -e and -æ were once transcribed as /ɪ/, but now agree with most other varieties of English with /i/). Words deriving from Greek long (η) end in /iː/ unless assimilated.

In the words mihi, tibi, sibi, by an old tradition, the final i was pronounced like final e above (i.e., as if spelled mihe, tibe, sibe).

A late and purely academic pronunciation distinguished final -ā from -a by pronouncing the former like "long a", /eɪ/: for instance, Oxford professor A. D. Godley
A. D. Godley
Alfred Denis Godley was a classical scholar and author of humorous poems. From 1910 to 1920 he was Public Orator at the University of Oxford, a post that involved composing citations in Latin for the recipients of honorary degrees. One of these was for Thomas Hardy who received an Honorary D. Litt...

 rhymed "day" with Rusticā. That this was not the usual pronunciation can be told from such forms as circa, infra, extra, in absentia, sub pœna, all of which have an originally long final vowel: circā, sub pœnā, etc. This use is distinct from the older tradition (in use in the 17th-18th centuries) had made all final as "long", regardless of their Latin length.

Vowel plus consonant cluster

The second class consists of vowels consonant clusters such as
ns, nt, nx, ps, x. In this class, the vowels are always short, except for u, which may be reduced to [ə].
Letter American British Australian Examples
a /æ/ æ æ æ climax, phalanx
e /ɛ/ ɛ ɛ e biceps, index
i /ɪ/ ɪ ɪ ɪ matrix, phœnix
o /ɒ/ ɑ ɒ ɔ Cyclops
u /ə/ ə ə ə exeunt, Pollux
y /ɪ/ ɪ ɪ ɪ pharynx, oryx

Vowel plus consonant

The third class consists of vowels followed by the consonants
l, m, n, r, s, t. The treatment of these endings is inconsistent. Generalizations include:
  1. All vowels are reduced before final r for /ər/: Cæsar, pauper, triumvir, Mentor, sulfur, martyr.
  2. All vowels are reduced to /ə/ before l: tribunal, Babel, pugil, consul.
  3. Except sometimes before t, a is reduced to /ə/ before any of this class of consonant: animal, memoriam, titan, atlas.
  4. All instances of u are reduced to /ə/ before any of this class of consonant: consul, dictum, locus.


The remaining endings are:
-at, -em, -en, -es, -et, -im, -is, -it, -on, -os, -ot. Of these, -em, -im, -is, -it, -on, -ot have two possible pronunciations, one with a short vowel and one with /ə/. Final -es and -ies are alike pronounced /iːz/. Final -eus may be pronounced containing the diphthong eu, juːs, or as if it were semivowel e followed by the ending -us, i.əs. However, even when pronounced as two syllables, -eus counts as a single syllable for the purpose of determining vowel length; that is, the syllable preceding the ending is considered the penult.

os /ɒs/ ɑs ɒs ɔs chaos, pathos, pharos
ot
/ɒt/, /ət/
ɑt ɒt ɔt aliquot
ət ət ət


This last pronunciation of -os is the expected one; however, in the masculine accusative plural, where the ending is historically , the academic prescription was the pronunciation /oʊs/. Such an ending is not found in English loan words or proper names.

History

Latin as traditionally pronounced by English speakers is part of the living history of spoken Latin through medieval French into English.

Three stages of development of A-L can thus be distinguished:

Stage I

Latin from the period when its orthography and grammar became standardized through to the pronunciation changes of Late Latin, while it was still a living language. Changes that took place in this period included:
  • the merger of f and ph as [f]
  • the change in pronunciation of v (formerly [w]) to [v] and of j (formerly [j]) to [dʒ].
  • the merger of i and y as [i]
  • the merger of e, æ and œ as [e]
  • the change of non-initial, unstressed, prevocalic [i] to [j]
  • the loss of distinctions of vowel length (merger of all long and short vowels)
  • the palatalization of t to [ts] before [j]

Stage II

Latin spoken in the context of Gallo-Romance and French from approximately the 6th to the 11th-12th centuries. During this period, Latin became a primarily written language, separated from the ordinary spoken language of the people. While it escaped many of the changes of pronunciation and grammar of Gallo-Romance, it did share a few of the changes of the spoken language. This was for the most part a period of stability.
Changes in this period included:
  • the palatalization of c and g to [ts] and [dʒ] before front vowels
  • the voicing of intervocalic s to [z]
  • the fronting of u to [y]
  • the restoration (based on spelling) of the vowels [i] and [e] from [j]

Stage III

Latin spoken in the context of English from the 11th/12th centuries to the present. This last stage provides the greatest and most complicated number of changes. It starts with the displacement of the native pronunciation of Latin under the Anglo-Saxon kings with that used in the north of France, around the time of the Norman conquest in 1066. The English and French pronunciations of Latin were probably identical down to the 13th century, but subsequently Latin as spoken in England began to share in specifically English sound changes. Latin, thus naturalized, acquired a distinctly English sound, increasingly different from the pronunciation of Latin in France or elsewhere on the Continent.

Some phases of development in this third stage can be reconstructed:

1200–1400

  • The adaptation of the French sounds to English:
    • [s] was substituted for [ts]. (The French sound changed at about the same time; however, A-L did not share related French simplifications such as [dʒ] > [ʒ].)
    • the vowels were given the values a [ɐ], e [ɛ], i [ɪ], o [ɔ], u [y]
    • [ʊ] was substituted for [y] in closed syllables
  • Stressed open penultimate vowels were lengthened, creating the short/long contrasts:
a [ɐ]:[ɐː], e [ɛ]:[ɛː], i [ɪ]:[iː], o [ɔ]:[ɔː]

1400–1600

  • Merger of unstressed open [ɛ] with [ɪ]
  • Non-syllable-initial, unstressed, prevocalic [ɪ] became [j] (a change almost identical to that of Late Latin)
  • Lengthening of the first of two vowels in hiatus
  • Lengthening of e [ɛ], i [ɪ], or o [ɔ] in pretonic initial syllables
  • Diphthongization of [iː] to [ɛi]
  • Lengthening of vowels in open syllables before [j] in the next syllable
  • Raising of [ɛː] and [ɔː] to [eː] and [oː].
  • Degemination of geminate consonants
  • Palatalization of [s] and [z] before [j]
  • Fronting of [ɐː] to [aː]

1600–1800

  • Monophthongization of ai to [aː] and au to [ɒː]
  • Change of [j] to [ɪ] (later → [i]) in many words, restoring original syllabicity.
  • Change of fronted u ([y]) to [jɪu]
  • Palatalization of [t d s z] before (usually unstressed) [jɪu] (later > [jə])
  • Loss of distinctive vowel length, creating the short/long contrasts: a [ɐ]:[a], e [ɛ]:[e], i [ɪ]:[ɛi], o [ɔ]:[o]
  • Lowering and unrounding of short [ʊ], [ɔ] to [ʌ], [ɑ]
  • Former long i [ɛi] becomes [ai]
  • Fronting and raising of short a [ɐ], long a [a], and long e [e] to [æ] [e] [i], creating the new contrasts: a [æ]: [e], e [ɛ]:[i], i [ɪ]:[ai], o [ɑ]:[o]
  • Beginning of vowel reductions to [ə].

1800–present

  • Development of [e] and [o] to diphthongs [ei] and [ou]
  • Laxing of [ei] [ou] (variously) to [eɪ] [oʊ], [ɛi] [ɔu], and the latter to [əu]
  • Continued vowel reductions to [ə] (a still current process).
  • Shortening of a in a stressed open penult syllable, e.g., data.

Other languages

A similar situation occurred in other regions, where the pronunciation of the local language influenced the pronunciation of Latin, eventually being replaced with reconstructed classical pronunciation. In German-speaking areas, traditional Germanized pronunciation of Latin is discussed at Deutsche Aussprache des Lateinischen , with reconstructed classical pronunciation at Schulaussprache des Lateinischen .

Further afield, the tradition of reading classical Chinese in Japanese is known as kanbun
Kanbun
The Japanese word originally meant "Classical Chinese writings, Chinese classic texts, Classical Chinese literature". This evolved into a Japanese method of reading annotated Classical Chinese in translation . Much Japanese literature was written in literary Chinese using this annotated style...

, and featured various annotations to the Chinese text to aid Japanese speakers.
