A syllable is a unit of organization for a sequence of speech sounds. For example, the word water is composed of two syllables: wa and ter. A syllable is typically made up of a syllable nucleus (most often a vowel
Vowel
In phonetics, a vowel is a sound in spoken language, such as English ah! or oh! , pronounced with an open vocal tract so that there is no build-up of air pressure at any point above the glottis.

Similar terms include disyllable (and disyllabic) for a word of two syllables; trisyllable (and trisyllabic) for a word of three syllables; and polysyllable (and polysyllabic), which may refer either to a word of more than three syllables or to any word of more than one syllable.

Syllable structure

In most theories of phonology, the general structure of a syllable (σ) consists of three segments:
Onset (ω): consonant, obligatory in some languages, optional or even restricted in others
Nucleus (ν): sonant, obligatory in most languages
Coda (κ): consonant, optional in some languages, highly restricted or prohibited in others
The syllable is usually considered right-branching, i.e. nucleus and coda are grouped together as a "rime" and are only distinguished at the second level. However, in some traditional descriptions of certain languages, the syllable is considered left-branching, i.e. onset and nucleus group below a higher-level unit, called a "body" or "core":
Rime (ρ): right branch, contrasts with onset, splits into nucleus and coda
Body or core: left branch, contrasts with coda, splits into onset and nucleus
In some theories the onset is strictly consonantal, thus necessitating another segment before the nucleus:
Initial (ι): often termed onset, but leaving out semi-vowels
Medial (μ): glide between initial, if any, and nucleus or rime
Final (φ): contrasts with initial, extended rime
Although every syllable has supra-segmental features, these are usually ignored if not semantically relevant, e.g. in tonal languages.
Tone

s (similar to the trees found in some types of syntax). Not all phonologists agree that syllables have internal structure; in fact, some phonologists doubt the existence of the syllable as a theoretical entity.

The nucleus is usually the vowel in the middle of a syllable. The onset is the sound or sounds occurring before the nucleus, and the coda (literally 'tail') is the sound or sounds that follow the nucleus. They are sometimes collectively known as the shell. The term rime covers the nucleus plus coda. In the one-syllable English word cat, the nucleus is a (the sound that can be shouted or sung on its own), the onset c, the coda t, and the rime at. This syllable can be abstracted as a consonant-vowel-consonant syllable, abbreviated CVC. Languages vary greatly in the restrictions on the sounds making up the onset, nucleus and coda of a syllable, according to what is termed a language's phonotactics

Onset

Most syllables have an onset. Some languages restrict onsets to be only a single consonant, while others allow multiconsonant onsets according to various rules. For example, in English, onsets such as pr-, pl- and tr- are possible but tl- is not (except very marginally in foreign words such as Tlingit

 no multiconsonant onsets are allowed at all.

Some languages require all syllables to have an onset; in these languages a null onset such as in the English word "at" is not possible. This is less strange than it may appear at first, as most such languages allow syllables to begin with a phonemic glottal stop
Glottal stop
The glottal stop, or more fully, the voiceless glottal plosive, is a type of consonantal sound used in many spoken languages. In English, the feature is represented, for example, by the hyphen in uh-oh! and by the apostrophe or [[ʻokina]] in Hawaii among those using a preservative pronunciation of...

 (the sound in the middle of English "uh-oh"). Furthermore, in English and most other languages, a word that begins with a vowel is automatically pronounced with an initial glottal stop when following a pause, whether or not a glottal stop occurs as a phoneme in the language. Consequently, few languages make a phonemic distinction between a word beginning with a vowel and a word beginning with a glottal stop followed by a vowel, since the distinction will generally only be audible following another word. (However, Hawaiian

This means that the difference between a syllable with a null onset and one beginning with a glottal stop is often purely a difference of phonological

 analysis, rather than the actual pronunciation of the syllable. In some cases, the pronunciation of a (putatively) vowel-initial word when following another word – particularly, whether or not a glottal stop is inserted – indicates whether the word should be considered to have a null onset.

 both require that a glottal stop be inserted between a word and a following, putatively vowel-initial word. Yet such words are said to begin with a vowel in German but a glottal stop in Arabic. The reason for this has to do with other properties of the two languages. For example, a glottal stop does not occur in other situations in German, e.g. before a consonant or at the end of word. On the other hand, in Arabic, not only does a glottal stop occur in such situations (e.g. Classical /saʔala/ "he asked", /raʔj/ "opinion", /dˤawʔ/ "light"), but it occurs in alternations that are clearly indicative of its phonemic status (cf. Classical /kaːtib/ "writer" vs. /maktuːb/ "written", /ʔaːkil/ "eater" vs. /maʔkuːl/ "eaten").

The writing system of a language may not correspond with the phonological analysis of the language in terms of its handling of (potentially) null onsets. For example, in some languages written in the Latin alphabet

, consonants have been analyzed as acting simultaneously as the coda of one syllable and the onset of the following syllable, as in 'bellow' bel-low, a phenomenon known as ambisyllabicity. It is argued that words such as arrow ˈæroʊ can't be divided into separately pronounceable syllables: neither /æ/ nor /ær/ is a possible independent syllable, and likewise with the other short vowels /ɛ ɪ ɒ ʌ ʊ/. However, Wells (1990) argues against ambisyllabicity in English, positing that consonants and consonant clusters are codas when after a stressed syllable followed by an unstressed syllable, or after a full vowel and followed by a reduced syllable, and are onsets in other contexts. (See English phonology#Phonotactics.)

The medial groups phonologically with the rime rather than the onset, and the combination of medial and rime is collectively known as the final.

Tone

In most languages, the pitch or pitch contour in which a syllable is pronounced conveys shades of meaning such as emphasis or surprise, or distinguishes a statement from a question. In tonal languages, however, the pitch of a word affects the basic lexical meaning (e.g "cat" vs. "dog") or grammatical meaning (e.g. past vs. present). In some languages, only the pitch itself (e.g. high vs. low) has this effect, while in others, especially East Asian languages such as Chinese

Sometimes syllable length is also counted as a suprasegmental feature; for example, in some Germanic languages, long vowels may only exist with short consonants and vice versa. However, syllables can be analyzed as compositions of long and short phonemes, as in Finnish and Japanese, where consonant gemination and vowel length are independent.

 (the names transliterated as "Israel", "Abraham", "Omar", "Ali" and "Abdullah", among many others, actually begin with semiconsonantic glides or with glottal or pharyngeal consonants). Conversely, some analyses of the Arrernte language of central Australia posit that no onsets are permitted at all in that language, all syllables being underlyingly of the shape VC(C).

Syllabification

Syllabification is the separation of a word into syllables, whether spoken or written. In most languages, the actually spoken syllables are the basis of syllabification in writing too. Due to the very weak correspondence between sounds and letters in the spelling of modern English, for example, written syllabification in English has to be based mostly on etymological i.e. morphological instead of phonetic principles. English "written" syllables therefore do not correspond to the actually spoken syllables of the living language.

(Syllabification may also refer to the process of a consonant becoming a syllable nucleus.)

Syllable division and ambisyllabicity

Most commonly, a single consonant between vowels is grouped with the following syllable (i.e. /CV.CV/), while two consonants between vowels are split between syllables (i.e. /CVC.CV/). In some languages, however, such as Old Church Slavonic

 of the language to be defined as requiring open syllables.) Contrarily, in some languages, any group of consonants that can occur at the end of a word is grouped with the following syllable.

In English, it has been disputed whether certain consonants occurring between vowels (especially following a stressed syllable and preceding an unstressed syllable) should be grouped with the preceding or following syllable. For example, a word such as better is sometimes analyzed as /ˈbɛt.ər/ and sometimes /ˈbɛ.tər/. Some linguists have in fact asserted that such words are "ambisyllabic", with the consonant shared between the preceding and following syllables. However, Wells (2002)http://www.phon.ucl.ac.uk/home/wells/syllabif.htm argues that this is not a useful analysis, and that English syllabification is simply /ˈCVC(C).V/.

Syllables and stress

Syllable structure often interacts with stress. In Latin
Latin
Latin is an Italic language originally spoken in Latium and Ancient Rome. It, along with most European languages, is a descendant of the ancient Proto-Indo-European language. Although it is considered a dead language, a number of scholars and members of the Christian clergy speak it fluently, and...

, for example, stress is regularly determined by syllable weight
Syllable weight
In linguistics, syllable weight is the concept that syllables pattern together according to the number and/or duration of segments in the rime. In classical poetry, both Greek and Latin, distinctions of syllable weight were fundamental to the meter of the line....

  • a long vowel in its nucleus
  • a diphthong

Syllables and vowel tenseness

Checked and free vowels
In phonetics and phonology, checked vowels are those that usually must be followed by a consonant in a stressed syllable, while free vowels are those that may stand in a stressed open syllable with no following consonant.-Usage:...

, as opposed to the tense vowels that are called free vowels because they can occur even in open syllables.

An obstruent is a consonant sound formed by obstructing airflow, causing increased air pressure in the vocal tract, such as [k], [d͡ʒ] and [f]. In phonetics, articulation may be divided into two large classes: obstruents and sonorants....

s:
[ɬχʷtɬtsxʷ] 'you spat on me'
[tsʼktskʷtsʼ] 'he arrived'
[xɬpʼχʷɬtɬpɬɬs] 'he had in his possession a bunchberry plant' (Bagemihl 1991:589, 593, 627)
[sxs] 'seal blubber'


In Bagemihl's survey of previous analyses, he finds that the word [tsʼktskʷtsʼ] would have been parsed into 0, 2, 3, 5, or 6 syllables depending which analysis is used. One analysis would consider all vowel and consonants segments as syllable nuclei, another would consider only a small subset as nuclei candidates, and another would simply deny the existence of syllables completely.
