Regular plurals

The plural morpheme
Morpheme
In linguistics, a morpheme is the smallest semantically meaningful unit in a language. The field of study dedicated to morphemes is called morphology. A morpheme is not identical to a word, and the principal difference between the two is that a morpheme may or may not stand alone, whereas a word,...

 in English is suffixed
Affix
An affix is a morpheme that is attached to a word stem to form a new word. Affixes may be derivational, like English -ness and pre-, or inflectional, like English plural -s and past tense -ed. They are bound morphemes by definition; prefixes and suffixes may be separable affixes...

 to the end of most nouns. Regular English plurals fall into three classes, depending upon the sound that ends the singular form:

Where a singular noun ends in a sibilant sound —/s/, /z/, /ʃ/, /ʒ/, /tʃ/ or /dʒ/— the plural is formed by adding /ɨz/. The spelling adds -es, or -s if the singular already ends in -e:
kiss kisses /ˈkɪsɨz/
phase phases /ˈfeɪzɨz/
dish dishes /ˈdɪʃɨz/
massage massages /məˈsɑːʒɨz/ or /ˈmæsɑːʒɨz/
witch witches /ˈwɪtʃɨz/
judge judges /ˈdʒʌdʒɨz/


When the singular form ends in a voiceless
Voice (phonetics)
Voice or voicing is a term used in phonetics and phonology to characterize speech sounds, with sounds described as either voiceless or voiced. The term, however, is used to refer to two separate concepts. Voicing can refer to the articulatory process in which the vocal cords vibrate...

 consonant
Consonant
In articulatory phonetics, a consonant is a speech sound that is articulated with complete or partial closure of the vocal tract. Examples are , pronounced with the lips; , pronounced with the front of the tongue; , pronounced with the back of the tongue; , pronounced in the throat; and ,...

 (other than a sibilant) —/p/, /t/, /k/, /f/ or /θ/— the plural is formed by adding /s/. The spelling adds -s. Examples:
lap laps /læps/
cat cats /kæts/
clock clocks /klɒks/
cuff cuffs /kʌfs/
death deaths /dɛθs/


For all other words (i.e. words ending in vowels or voiced non-sibilants) the regular plural adds /z/, represented orthographically
Orthography
The orthography of a language specifies a standardized way of using a specific writing system to write the language. Where more than one writing system is used for a language, for example Kurdish, Uyghur, Serbian or Inuktitut, there can be more than one orthography...

 by -s:
boy boys /bɔɪz/
girl girls /ɡɜrlz/
chair chairs /tʃɛərz/


Morphophonetically, these rules are sufficient to describe most English plurals. However, there are several complications introduced in spelling.

The -oes rule: most nouns ending in o preceded by a consonant
Consonant
In articulatory phonetics, a consonant is a speech sound that is articulated with complete or partial closure of the vocal tract. Examples are , pronounced with the lips; , pronounced with the front of the tongue; , pronounced with the back of the tongue; , pronounced in the throat; and ,...

 also form their plurals by adding -es :
hero heroes
potato potatoes
volcano volcanoes or volcanos

The -ies rule: nouns ending in a y preceded by a consonant usually drop the y and add -ies . This is taught to many North American and British students with the mnemonic: "Change the y to i and add es":
cherry cherries
lady ladies

However, proper nouns (particularly those for people or places) ending in a y preceded by a consonant form their plurals regularly:
Germany Germanys (as in The two Germanys were unified in 1990; this rule is commonly not adhered to as several book titles show; Sicilies

Harry Harrys (as in There are three Harrys in our office)

The rule does not apply to words that are merely capitalized common nouns:
P&O Ferries (from ferry)

Other exceptions include lay-bys and stand-bys.

Words ending in a y preceded by a vowel form their plurals regularly:
day days
monkey monkeys

(Money/Monies is an exception, but money can also form its plural regularly.)

These may be the lower lip against the upper teeth, in the case of ; the back of the tongue against the soft palate, in the case of German , the final consonant of Bach; or...

s /f/, /θ/ mutated to voiced fricatives before a voiced ending. In some words this voicing survives in the modern English plural. In the case of /f/ changing to /v/, the mutation is indicated in the orthography as well; also, a silent e is added in this case if the singular does not already end with -e:
bath baths /bɑːðz/, /bæðz/
mouth mouths /maʊðz/
calf calves /kɑːvz/, /kævz/
leaf leaves (see footnote), /liːvz/
knife knives /naɪvz/
life lives

In addition, there is one word where /s/ is voiced in the plural:
house houses /haʊzɨz/


Many nouns ending in /f/ or /θ/ (including all words where /f/ is represented orthographically by gh or ph) nevertheless retain the voiceless consonant:

Irregular plurals

There are many other less regular ways of forming plurals, usually stemming from older forms of English or from foreign borrowings.

Nouns with identical singular and plural

Some nouns spell their singular and plural exactly alike; some linguists regard these as regular plurals. Many of these are the names of animals:
deer
moose
sheep
bison
salmon
pike
trout
fish
swine


The plural deers is listed in some dictionaries. As a general rule, game or other animals are often referred to in the singular for the plural in a sporting context: "He shot six brace of pheasant", "Carruthers bagged a dozen tiger last year", whereas in another context such as zoology or tourism the regular plural would be used. Similarly, nearly all kinds of fish have no separate plural form (though there are exceptions -- such as rays, sharks or lampreys). And the word "fish" itself is also troublesome, being generally used as a plural when in the context of food, but forming a regular plural otherwise (thus "three lots of fish and chips", "the industry landed 5,200 tonnes of fish in 1998" but "the order

 of the loaves and fishes", the phrase "sleep with the fishes"). The usage does vary, however, so that for example the phrase "five fish in an aquarium" might to another native user be "five fishes in an aquarium". Using the plural form fish could imply many individual fish(es) of the same species while fishes could imply many individual fish(es) of differing species.

Other nouns that have identical singular and plural forms include:

Irregular -(e)n plurals

The plural of a few nouns can also be formed from the singular by adding -n or -en, stemming from the Old English weak declension:

. The general trend with loanwords is toward what is called Anglicization or naturalization, that is, the re-formation of the word and its inflections as normal English words. Many nouns (particularly ones from Latin) have retained their original plurals for some time after they are introduced. Other nouns have become Anglicized, taking on the normal "s" ending. In some cases, both forms are still competing.

The choice of a form can often depend on context: for a linguist, the plural of appendix

The choice of form can also depend on the level of discourse: traditional Latin plurals are found more often in academic and scientific contexts, whereas in daily speech the Anglicized forms are more common. In the following table, the Latin plurals are listed, together with the Anglicized forms when these are more common.
  • Final a becomes -ae (also -æ), or just adds -s:
    alumna alumnae
    formula formulae/formulas
    encyclopaedia (or encyclopædia) / encyclopedia | encyclopaedias / encyclopedias (encyclopaediae and encyclopediae are rare)
  • Final ex or ix becomes -ices , or just adds -es:
    index indices /ˈɪndɨsiːz/ or indexes
    matrix matrices /ˈmeɪtrɨsiːz/
    vertex vertices /ˈvɜrtɨsiːz/

Some people treat process as if it belonged to this class, pronouncing processes /ˈprɒsɨsiːz/ instead of standard /ˈprɒsɛsɨz/. Since the word comes from Latin processus, whose plural in the fourth declension is processūs with a long u, this pronunciation is by analogy, not etymology.
  • Final is becomes es :
    axis axes /ˈæksiːz/
    crisis crises /ˈkraɪsiːz/
    testis testes /ˈtɛstiːz/

Axes, the plural of axis, is pronounced differently from axes (/ˈæksɨz/), the plural of ax(e).

    datum data (Now usually treated as a singular mass noun in both informal and educated usage, but usage in scientific publications shows a strong American/British divide. American usage generally prefers to treat data as a singular in all contexts, including in serious and academic publishing. British usage now widely accepts treating data as singular in standard English, including educated everyday usage at least in non-scientific use. British scientific publishing usually still prefers treating data as a plural. Some British university style guides recommend using data for both the singular and the plural use and some recommend treating it only as a singular in connection with computers.)

    Māori or te reo Māori , commonly te reo , is the language of the indigenous population of New Zealand, the Māori. It has the status of an official language in New Zealand...

     origin can either take an -s or have no separate plural form. Words more connected to Māori culture and used in that context tend to retain the same form, while names of flora and fauna may or may not take an -s, depending on context. Many regard omission as more correct:
    kiwi kiwi/kiwis
    kowhai kowhai/kowhais
    Māori Māori/(occasionally Māoris)
    marae marae
    tui tuis/tui
    waka waka

When referring to the bird, kiwi may or may not take an -s; when used as an informal term for a New Zealander, it always takes an -s.

Māori, when referring to a person of that ethnicity, does not usually take an -s. Many speakers avoid the use of Māori as a noun, and instead use it only as an adjective.

Words better known in the plural

Some words of foreign origin are much better known in the plural; usage of the original singular may be considered pedantic or actually incorrect or worse by some speakers. In common usage, the original plural is considered to be the singular form. In many cases, back-formation

A single piece of data is sometimes referred to as a data point. In engineering, drafting, surveying, and geodesy, and in weight and balance calculations for aircraft, a datum
Datum
A geodetic datum is a reference from which measurements are made. In surveying and geodesy, a datum is a set of reference points on the Earth's surface against which position measurements are made, and an associated model of the shape of the earth to define a geographic coordinate system...

 (plural datums or data) is a reference point, surface, or axis on an object or the earth’s surface against which measurements are made.

Some plural nouns are used as such —invariably being accompanied by a plural verb form— while their singular forms are rarely encountered:
nuptial nuptials
phalanx phalanges
tiding tidings
victual victuals
viscus viscera

In medical terminology, a phalanx is any bone of the finger or toe. A military phalanx is pluralized phalanxes.

A related phenomenon is the confusion of a foreign plural for its singular form:
criterion criteria
phenomenon phenomena
consortium consortia
symposium symposia


Magazine was derived from Arabic via French. It was originally plural, but in French and English, it is always regarded as singular.

Plurals of numbers

English, like some other languages, treats large numerals as nouns (cf. "there were ten soldiers" and "there were a hundred soldiers"). Thus, dozens is preferred to tens, while hundreds and thousands are also completely acceptable.

Plurals of numbers differ according to how they are used. The following rules apply to dozen, score, hundred, thousand, million, and similar terms:
  • When modified by a number, the plural is not inflected, that is, has no -s added. Hence one hundred, two hundred, etc. For vaguer large numbers, one may indifferently say several hundred or several hundreds.
  • When used alone, or followed by a prepositional phrase, the plural is inflected: dozens of complaints, scores of people. However, either complaints by the dozen or complaints by the dozens is acceptable (although differing in meaning).
  • The preposition of is used when speaking of nonspecific items identified by pronouns: two hundred of these, three dozen of those. The of is not used for a number of specific items: three hundred oscilloscope
    Oscilloscope
    An oscilloscope is a type of electronic test instrument that allows observation of constantly varying signal voltages, usually as a two-dimensional graph of one or more electrical potential differences using the vertical or 'Y' axis, plotted as a function of time,...

    s. However, if the pronoun is included with the specific item, the of is used: five million of those dollar bills.


A sagan of any kind of items is at least four billion, as in billions and billions. Hence, "about a sagan of micrometeorites."

Nouns used attributively

Nouns used attributively to qualify other nouns are generally in the singular, even though for example, a dog catcher catches more than one dog, and a department store has more than one department. This is true even for some binary nouns where the singular form is not found in isolation, such as a trouser mangle or the scissor kick. This is also true where the attribute noun is itself qualified with a number, such as a twenty-dollar bill, a ten-foot pole or a two-man tent. The plural is used for pluralia tantum nouns: a glasses case is for eyeglasses, while a glass case is made of glass (but compare eyeglass case); also an arms race versus arm wrestling. The plural may be used to emphasise the plurality of the attribute, especially in British English

: a careers advisor, a languages expert. The plural is also more common with irregular plurals for various attributions: women killers are women who kill, whereas woman killers are those who kill women.

Defective nouns

Some nouns have no singular form. Such a noun is called a plurale tantum
Plurale tantum
A plurale tantum is a noun that appears only in the plural form and does not have a singular variant for referring to a single object...

 (see also Words better known in the plural above):
cattle, billiards, clothes, measles, news, thanks


Some of these do have singular adjective forms, such as billiard ball. In addition, some are treated as singular in certain sentences, e.g., "billiards is a game played on a table with billiard balls and a cue", "measles is an infectious disease". Thanks is usually treated as a plural. Although "cow" is sometimes used in colloquial English for cattle, the term is age and gender specific.

A particular set of nouns, describing things having two parts, comprises the major group of pluralia tantum in modern English:
glasses (a pair of spectacles), pants, panties, pantyhose
Pantyhose
Pantyhose are sheer, close-fitting legwear, covering the wearer's body from the waist to the feet. Mostly considered to be a woman's and girl's garment, pantyhose appeared in the 1960s, and they provided a convenient alternative to stockings...

, tongs (metalworking & cooking), trousers
Trousers
Trousers are an item of clothing worn on the lower part of the body from the waist to the ankles, covering both legs separately...

, etc.


These words are interchangeable with a pair of scissors, a pair of trousers, and so forth. In the American fashion industry it is common to refer to a single pair of pants as a pant —though this is a back-formation

, the English word (deriving from the French pantalon) was originally singular. In the same field, one half of a pair of scissors separated from the other half is, rather illogically, referred to as a half-scissor. Tweezers used to be part of this group, but tweezer has come into common usage only since the second half of the twentieth century.

In linguistics, a mass noun is a noun that refers to some entity as an undifferentiated unit rather than as something with discrete subsets. Non-count nouns are best identified by their syntactic properties, and especially in contrast with count nouns. The semantics of mass nouns are highly...

s (or uncountable nouns) do not represent distinct objects, so the singular and plural semantics do not apply in the same way. Some examples:
  • Abstract nouns

deceit, information, cunning, and nouns derived from adjectives, such as honesty, wisdom, beauty, intelligence, poverty, stupidity, curiosity, and words ending with "ness", such as goodness, freshness, laziness, and nouns which are homonyms of adjectives with a similar meaning, such as good, bad (can also use goodness and badness), hot, and cold.

Referring to the musical style as a whole.

Some mass nouns can be pluralized, but the meaning in this case may change somewhat. For example, when I have two grain(s) of sand, I do not have two sands; I have sand. There is more sand in your pile than in mine, not more sands. However, there could be the many "sands of Africa" — either many distinct stretches of sand, or distinct types of sand of interest to geologist

It is rare to pluralize furniture in this way. Nor is information ever pluralized.

There is only one class of atoms called oxygen, but there are several isotopes of oxygen, which might be referred to as different oxygens. In casual speech, oxygen might be used as shorthand for "oxygen atoms", but in this case, it is not a mass noun, so it is entirely sensible to refer to multiple oxygens in the same molecule.

One would interpret Bob's wisdoms as various pieces of Bob's wisdom (that is, don't run with scissors, defer to those with greater knowledge), deceits as a series of instances of deceitful behavior (lied on income tax, dated my wife), and the different idlenesses of the worker as plural distinct manifestations of the mass concept of idleness (or as different types of idleness, "bone lazy" versus "no work to do").

Specie versus species make a fascinating case. Both words come from a Latin word meaning "kind", but they do not form a singular-plural pair. In Latin, specie is the ablative singular form, while species is the nominative form, which happens to be the same in both singular and plural. In English, species behaves similarly —as a noun with identical singular and plural— while specie is treated as a mass noun, referring to money in the form of coins (the idea is of "[payment] in kind").

, with which they end, and are pluralized in typical fashion:
able seaman able seamen
head banger head bangers
yellow-dog contract yellow-dog contracts


A compound that has one head, with which it begins, usually pluralizes its head:
attorney general attorneys general
bill of attainder bills of attainder
court martial courts martial
director general directors general
fee simple absolute fees simple absolute
governor-general governors-general
passerby passersby
ship of the line ships of the line
son-in-law sons-in-law
minister-president ministers-president
knight-errant knights-errant
procurator fiscal (in Scotland) procurators fiscal


It is common in informal speech to instead pluralize the last word in the manner typical of most English nouns, but in edited prose, the forms given above are preferred.

If a compound can be thought to have two heads, both of them tend to be pluralized when the first head has an irregular plural form:
man-child men-children
manservant menservants
woman doctor women doctors


Two-headed compounds in which the first head has a standard plural form, however, tend to pluralize only the final head:
city-state city-states
nurse-practitioner nurse-practitioners
scholar-poet scholar-poets


In military usage, the term general, as part of an officer's title, is etymologically an adjective, but it has been adopted as a noun and thus a head, so compound titles employing it are pluralized at the end:
brigadier general brigadier generals
major general major generals


For compounds of three or more words that have a head (or a term functioning as a head) with an irregular plural form, only that term is pluralized:
man-about-town men-about-town
man-of-war men-of-war
woman of the street women of the street


For many other compounds of three or more words with a head at the front —especially in cases where the compound is ad hoc and/or the head is metaphorical— it is generally regarded as acceptable to pluralize either the first major term or the last (if open when singular, such compounds tend to take hyphens when plural in the latter case):
ham on rye hams on rye/ham-on-ryes
jack-in-the-box jacks-in-the-box/jack-in-the-boxes
jack-in-the-pulpit jacks-in-the-pulpit/jack-in-the-pulpits


With a few extended compounds, both terms may be pluralized—again, with an alternative (which may be more prevalent, e.g., heads of state):
head of state heads of states/heads of state
son of a bitch sons of bitches/sons-of-a-bitch


With extended compounds constructed around o, only the last term is pluralized (or left unchanged if it is already plural):
cat-o'-nine-tails cat-o'-nine-tails
jack-o'-lantern jack-o'-lanterns
will-o'-the-wisp will-o'-the-wisps

Compounds from the French

Many English compounds have been borrowed
Loanword
A loanword is a word borrowed from a donor language and incorporated into a recipient language. By contrast, a calque or loan translation is a related concept where the meaning or idiom is borrowed rather than the lexical item itself. The word loanword is itself a calque of the German Lehnwort,...

 directly from the French, and these generally follow a somewhat different set of rules. French-loaned compounds with a head at the beginning tend to pluralize both words, according to French practice:
agent provocateur agents provocateurs
entente cordiale ententes cordiales
fait accompli faits accomplis
idée fixe idées fixes


For compounds adopted directly from the French where the head comes at the end, it is generally regarded as acceptable either to pluralize both words or only the last:
beau geste beaux gestes/beau gestes
belle époque belles époques/belle époques
bon mot bons mots/bon mots
bon vivant bons vivants/bon vivants
bel homme beaux hommes


If the adjectives beau "beautiful/handsome", nouveau "new", or vieux "old" precede a masculine singular noun beginning with a vowel or a mute "h", they are changed to bel, nouvel, and vieil to help ease the pronunciation. The normal plural rule applies to plural nouns.

French-loaned compounds longer than two words tend to follow the rules of the original language, which usually involves pluralizing only the head at the beginning:
aide-de-camp aides-de-camp
cri de coeur cris de coeur
coup d'état coups d'état
tour de force tours de force

but:
tête-à-tête tête-à-têtes


A distinctive case is the compound film noir. For this French-loaned artistic term, English-language texts variously use as the plural films noirs, films noir, and, most prevalently, film noirs. The 11th edition of the standard Merriam-Webster's Collegiate Dictionary (2006) lists film noirs as the preferred style. Three primary bases may be identified for this:
  1. Unlike other compounds borrowed directly from the French, film noir is used to refer primarily to English-language cultural artifacts; a typically English-style plural is thus unusually appropriate.
  2. Again, unlike other foreign-loaned compounds, film noir refers specifically to the products of popular culture; consequently, popular usage holds more orthographical authority than is usual.
  3. English has adopted noir as a stand-alone noun in artistic contexts, leading it to serve as the lone head in a variety of compounds (e.g., psycho-noir, sci-fi noir).

Thus, more than one lowlife are lowlifes, not "lowlives", according to Pinker.

. While heat is a mass noun, whereas avalanche is a normal counting noun, in the context of a team name, both words operate as this special type of collective noun. Just as with the Red Sox or the White Sox, any one of the twelve current members of Miami's pro basketball squad is a Heat (questionable). Similarly, any individual member of the Colorado Avalanche is an Avalanche. However, where one may say something like "two Red Sox struck out" or "four White Sox doubled consequitively", the equivalent term is invariably used as an adjective when referring to multiple players of one of the teams named in this increasingly popular way: "two Heat players fought" or "four Avalanche players scored" (The followers of the Avalanche have a little more flexibility available to them, with "Avs" as the team's unofficial, but widely used nickname).

In not every case above is it certain that the name is ever used in its noun form to refer to anything but the collective — i.e., not even to an individual player. In other cases, it is possible that the name is sometimes used in its noun form (with or without a terminal s appended) to refer to multiple players, short of the whole collective. Note that in the above list, there is a case of an irregular plural in the "Minnesota Lynx", since the plural of "lynx" is "lynx". For example, "The scout spotted 20 lynx living in the neighborhood of the Great Bear Lake

 team. The club is named after the song the "St. Louis Blues", which makes the team name Blues an irregularly pluralized word to begin with —one whose plural is identical to its singular. By this reckoning, then, an individual team member would also be a "Blues". However, because the name is spelled like a regular plural, its use as a collective noun leads to a process of back-formation

, with the result that a single player on the team is known as a "Blue". This team's name's distinctive orthographical nature further allows it to be used freely as a counting noun, so that one may speak of, for instance, "two Blues in the penalty box".

, Pinker asked, Why is the name the Marlins "given that those fish are referred to in the plural as marlin?" An analogous question could be asked about the Maple Leafs. Pinker's answer comes down to this: "A name is not the same thing as a noun." Consequently, names (and nouns that derive from names) based on nouns with irregular plurals do not acquire them — though, as we see with Red Sox, new irregularities may arise.

Nouns with multiple plurals

Some nouns have two plurals, one used to refer to a number of things considered individually, the other to refer to a number of things collectively. In some cases, one of the two is nowadays archaic or dialectal.
brother brothers brethren
cannon cannons cannon
child children childer
cloth cloths clothes
cow cows kine
die dice dies
fish fish fishes
iris (plant) iris irises
penny pennies pence
person persons people
pig pigs swine
sow sows swine


Brethren was used exclusively earlier, but over time, it has been replaced by brothers. Brethren is still used in some contexts such as the brethren of a monastic order.

Childer has all but disappeared, but can still be seen in Childermas (Innocents' Day).

Clothes formerly referred collectively to all of a household's washable cloth articles, but clothes is now used almost exclusively for the garments of people and doll
Doll

 as the plural (and increasingly as the singular) in the sense of a small random number generator. Dice is also the accepted plural form of die in the semiconductor industry. On gambling and games, we may roll one die or toss two or three dice.

Fish: the plural for one species of fish, or caught fish, is fish, but for the plural of fish of multiple individuals or species fishes is used. Fishes is also a word with a Biblical connotation.

For multiple plants, iris is used, but irises is used for multiple blossoms.

If one has several (British) one-penny pieces, one has several pennies. Pence is used for an amount of money, which can be made up of a number of coins of different denominations: one penny and one five-penny piece are together worth six pence. The suffixed minor currency unit of "p" (/pi/) is often vocalised, where such small divisions of currency are discussed in common speech, and used for both the singular and the "amount plural", but "number plurals" build upon the base values and any omission of the unit shifts the plural to the coin's numerator (e.g. "I have a one /pi/ and three twenty /piz/ and two fifties in my pocket. I cannot believe that I only have one pound

, sixty-one /pi/ left after last night."). In written speech, a number of coins might be "two 10ps", although those that prefer to use apostrophes for initialisms might decide to use the variant of "two 10p's".

Penny and pennies also refer to one or more American or Canadian one-cent pieces, though in American and Canadian usage, a nickel is worth five cents, not five pence. Also, a dime

In linguistics and etymology, suppletion is traditionally understood as the use of one word as the inflected form of another word when the two words are not cognate. For those learning a language, suppletive forms will be seen as "irregular" or even "highly irregular". The term "suppletion" implies...

 plural of person (one person, many people). However, in legal and other formal contexts, the plural of person is persons; furthermore, people can also be a singular noun with its own plural (for example, "We are many persons, from many peoples").

Plurals of symbols and initialisms

Individual letters and abbreviations whose plural would be ambiguous if only an -s were added are pluralized by adding -'s.
mind your p's and q's
A.A.'s and B.A.'s
the note had three PS's


Opinion is divided on whether to extend this use of the apostrophe to related but nonambiguous cases, such as the plurals of numerals (e.g., 1990's vs. 1990s) and words used as terms (e.g., "his writing uses a lot of but's" vs. "his writing uses a lot of buts"). Some writers favor the use of the apostrophe as consistent with its application in ambiguous cases; others say it confuses the plural with the possessive

 -'s and should be avoided whenever possible in pluralization, a view with which The Chicago Manual of Style concurs.

English and many other European languages form the plural of a one-letter abbreviation by doubling it: p. ("page"), pp. ("pages"); l. ("line"), ll. ("lines"). These abbreviations are used in literary work, such as footnotes and bibliographies.

Acronyms are initialisms that are used and pronounced as if they were words. For example, we have AMTRAK, HAL, LEM, NASA, and NATO. These contrast with the different variety that are read aloud one letter at a time: {C.I.A., C.S.M., D.O.D., E.U., G.C.M., G.P.S., I.B.M., N.A.C.A., N.S.A., R.C.A., R.P.M., S.S.T., T.W.A., U.S.S.R., W.P.A., etc.}

The most consistent approach for pluralizing pronounceable acronyms is to simply add a lowercase "s" as its suffix. This works even for acronyms ending with an s, such as with CASs , while still making it possible to use the possessive form ("'s") for the acronyms without confusion. (One sometimes sees "-es" added, which also works acceptably: "OSes.") The old, old style of pluralizing single letters with "'s" was naturally extended to acronyms when they were all commonly written with periods. This form is still preferred by some people for all initialisms and thus "'s" as a suffix is often seen in informal usage.

Plural to singular by back-formation

Some words have unusually formed singulars and plurals, but develop "normal" singular-plural pairs by back-formation
Back-formation
In etymology, back-formation is the process of creating a new lexeme, usually by removing actual or supposed affixes. The resulting neologism is called a back-formation, a term coined by James Murray in 1889...

. For example, pease (modern peas) was in origin a singular with plural peasen. However, pease came to be analysed as plural by analogy, from which a new singular pea was formed; the spelling of pease was also altered accordingly, surviving only in the name of the dish pease porridge or pease pudding. Similarly, termites was the three-syllable plural of termes; this singular was lost, however, and the plural form reduced to two syllables. Syringe is a back-formation from syringes, itself the plural of syrinx
Syrinx
In classical mythology, Syrinx was a nymph and a follower of Artemis, known for her chastity. Pursued by the amorous Greek god Pan, she ran to the river's edge and asked for assistance from the river nymphs. In answer, she was transformed into hollow water reeds that made a haunting sound when...

 cherise. Phases was once the plural of phasis, but the singular is now phase.

Kudos is a singular Greek word meaning praise, but is often taken to be a plural. At present, however, kudo is considered an error, though the usage is becoming more common as kudos becomes better known. The name of the Greek sandwich style gyros is increasingly undergoing a similar transformation.

The term, from Latin, for the main upper arm flexor in the singular is the biceps muscle (from biceps brachii); however, many English speakers take it to be a plural and refer to the muscle of only one arm, by back-formation, as a bicep. The correct —although very seldom used— Latin plural would be bicipites.

The word sastrugi (hard ridges on deep snow) is of Russian origin and its singular is sastruga; but the imaginary Latin-type singular sastrugus has sometimes been used.

Place names

Geographical place names ending with an "s" generally function as grammatically singular even if they look plural, for example: Arkansas, Athens, the Andes

 takes -man or -woman, there are three options: pluralize to -men or -women if referring to individuals, and use the root alone if referring to the whole nation, or add people.
Dutchman
Dutchwoman
Dutchmen
Dutchwomen
the Dutch
Englishman
Englishwoman
Englishmen
Englishwomen
the English
Frenchman
Frenchwoman
Frenchmen
Frenchwomen
the French
Irishman
Irishwoman
Irishmen
Irishwomen
the Irish
Scotsman
Scotswoman
Scotsmen
Scotswomen

Welshman
Welshwoman
Welshmen
Welshwomen
the Welsh

One can say "a Scots(wo)man" or "a Scot", "Scots(wo)men", "Scottish people", or "Scots", and "the Scottish" or "the Scots". (Scotch is considered old fashioned.)

Several peoples have names that are simple nouns and can be pluralized by the addition of either -s or -ish (the later case often calls for the elimination of terminal letters so the pluralizing suffix can be connected directly with the last consonant of the root):
Dane Danes the Danes
the Danish
Finn Finns the Finns
the Finnish
Spaniard Spaniards the Spaniards
the Spanish (much more common)
Swede Swedes the Swedes
the Swedish

Names of peoples that end in -ese take no plural:
Chinese Chinese
Chinese people
the Chinese
Japanese Japanese
Japanese people
the Japanese

Other names of peoples that have no plural form include Swiss and Québécois, although the latter is sometimes interchangeable with Quebec(k)er, which pluralizes as Quebec(k)ers.

Most names for Native Americans are not pluralized:
Blackfoot
Cherokee
Cree
Comanchee
Delaware
Hopi
Iroquois
Kiowa
Navajo
Ojibwa
Sioux
Zuni, for example


Some exceptions include Algonquins, Apaches, Aztecs, Black Hawks, Chippewas, Hurons, Incas, Mayans, Mohawks, Oneidas, and Seminoles. Note also the following words borrowed from Inuktitut

")

Names of most other peoples of the world are pluralized using the normal English rules.

Discretionary plurals

A number of words like army, company, crowd, fleet, government, majority, mess, number, pack, and party may refer either to a single entity or the members of the set that compose it. Thus, as H. W. Fowler describes, in British English
British English
British English, or English , is the broad term used to distinguish the forms of the English language used in the United Kingdom from forms used elsewhere...

 they are "treated as singular or plural at discretion"; Fowler notes that occasionally a "delicate distinction" is made possible by discretionary plurals: "The Cabinet is divided is better, because in the order of thought a whole must precede division; and The Cabinet are agreed is better, because it takes two or more to agree." Also in British English, names of towns and countries take plural verbs when they refer to sports teams but singular verbs when they refer to the actual place: England

, such words are invariably treated as singular.

"Snob plurals"

Another type of irregular plural occurs in the register of the English upper classes in the context of field sports, where the singular form is used in place of the plural, as in "two lion" or "five pheasant". Eric Partridge
