From Wikipedia, the free encyclopedia

A syllable (Greek: συλλαβή) 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) with optional initial and final margins (typically, consonants).

Syllables are often considered the phonological "building blocks" of words. They can influence the rhythm of a language, its prosody, its poetic meter, its stress patterns, etc.

Syllablic writing began several hundred years before the first letters. The earliest recorded syllables are on tablets written around 2800 BC in the Sumerian city of Ur. This shift from pictograms to syllables has been called 'the most important advance in the history of writing'.[1]

A word that consists of a single syllable (like English dog) is called a monosyllable (such a word is monosyllabic), while a word consisting of two syllables (like puppy) is called a disyllable (such a word is disyllabic). A word consisting of three syllables (such as Wolverine) is called a trisyllable (the adjective form is trisyllabic). A word consisting of more than three syllables (such as intelligence) is called a polysyllable (and could be described as polysyllabic), although this term is often used to describe words of two syllables or more.


Syllable structure

The general structure of a syllable consists of the following segments:

  • Onset (obligatory in some languages, optional or even restricted in others)
  • Rime
    • Nucleus (obligatory in all languages)
    • Coda (optional in some languages, highly restricted or prohibited in others)
tree representation of a CVC syllable

In some theories of phonology, these syllable structures are displayed as tree diagrams (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.[2]

The syllable nucleus is typically a sonorant, usually making a vowel sound, in the form of a monophthong, diphthong, or triphthong, but sometimes sonorant consonants like [l] or [r]. The syllable onset is the sound or sounds occurring before the nucleus, and the syllable coda (literally 'tail') is the sound or sounds that follow the nucleus. The term rime covers the nucleus plus coda. In the one-syllable English word cat, the nucleus is a, the onset c, the coda t, and the rime at. This syllable can be abstracted as a consonant-vowel-consonant syllable, abbreviated CVC.

Generally, every syllable requires a nucleus. Onsets are extremely common, and some languages require all syllables to have an onset. (That is, a CVC syllable like cat is possible, but a VC syllable such as at is not.) A coda-less syllable of the form V, CV, CCV, etc. is called an open syllable (or free syllable), while a syllable that has a coda (VC, CVC, CVCC, etc.) is called a closed syllable (or checked syllable). Note that they have nothing to do with open and close vowels. All languages allow open syllables, but some, such as Hawaiian, do not have closed syllables.

A heavy syllable is one with a branching rime or branching nucleus – this is a metaphor, based on the nucleus or coda having lines that branch in a tree diagram. In some languages, heavy syllables include both VV (branching nucleus) and VC (branching rime) syllables, contrasted with V, which is a light syllable. In other languages, only VV syllables (ones with a long vowel or diphthong) are heavy, while both VC and V syllables are light. The difference between heavy and light frequently determines which syllables receive stress—this is the case in Latin and Arabic, for example. In moraic theory, heavy syllables are said to have two moras, while light syllables are said to have one. Japanese is generally described this way.

In other languages, including English, a consonant may be analyzed as acting simultaneously as the coda of one syllable and the onset of the following syllable, a phenomenon known as ambisyllabicity. Examples include words such as arrow /ˈæroʊ/, error /ˈɛrər/, mirror /ˈmɪrər/, borrow /ˈbɒroʊ/, burrow /ˈbʌroʊ/, which 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/.

In traditional Chinese descriptions of tone, the so-called entering tones are the tonic possibilities on closed syllables ending in a stop consonant such as /p, t, k/.

Syllables and suprasegmentals

The domain of suprasegmental features is the syllable and not a specific sound, that is to say, they affect all the segments of a syllable:

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.

Syllables and phonotactic constraints

Phonotactic rules determine which sounds are allowed or disallowed in each part of the syllable. English allows very complicated syllables; syllables may begin with up to three consonants (as in string or splash), and occasionally end with as many as four (as in prompts). Many other languages are much more restricted; Japanese, for example, only allows /ɴ/ and a chroneme in a coda, and has no consonant clusters at all, as the onset is composed of at most one consonant.[3]

There are languages that forbid empty onsets, such as Hebrew and Arabic (the names transliterated as "Israel", "Abraham", "Omar", "Ali" and "Abdullah", among many others, actually begin with semiconsonantic glides or with glottal or pharyngeal consonants).


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. However, 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.)


Many English speakers have a strong feeling that consonants after stressed short vowels belong with the previous syllable, /ˈCVC.V/, as in competitive /kəm.ˈpɛt.ɨ.tɪv/ and better /ˈbɛt.ər/, and even with consonant clusters, such as banker /ˈbæŋk.ər/ and selfish /ˈCVCC.VC/ versus shellfish /ˈCVC.CVC/. This is at odds with the universal tendency for /CV.CV/ syllabification, and so the concept of ambisyllabicity was developed, with the idea that these consonants are shared between the preceding and following syllables. However, Wells (2002)[1] 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, for example, stress is regularly determined by syllable weight, a syllable counting as heavy if it has at least one of the following:

In each case the syllable is considered to have two moras.

Syllables and vowel tenseness

In most Germanic languages, lax vowels can only occur in closed syllables. Therefore, these vowels are also called checked vowels, as opposed to the tense vowels that are called free vowels because they can occur in open syllables.

Syllable-less languages

The notion of syllable is challenged by languages that allow long strings of consonants without any intervening vowel or sonorant. Languages of the Northwest coast of North America, including Salishan and Wakashan languages, are famous for this. For instance, these Nuxálk (Bella Coola) words contain only obstruents:

[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.

This type of phenomenon has also been reported in Berber languages (such as Indlawn Tashlhiyt Berber) and Mon-Khmer languages (such as Semai, Temiar, Kammu). Even in English there are a few utterances that have no vowels; for example, shh (meaning "be quiet") and psst (a sound used to attract attention).

Indlawn Tashlhiyt Berber:

[tftktst tfktstt] 'you sprained it and then gave it'
[rkkm] 'rot' (imperf.) (Dell & Elmedlaoui 1985, 1988)


[kckmrʔɛːc] 'short, fat arms' (Sloan 1988)

Simple English

A syllable is a unit of pronunciation uttered without interruption,[1] loosely, a single sound. [2] All words are made from at least one syllable.

Monosyllables have only one vowel sound; polysyllables have more than one. If a syllable ends with a consonant, it is called a closed syllable. If a syllable ends with a vowel, it is called an open syllable. Patterns of syllables can be shown with C and V (C for 'consonant', V for 'vowel'). Closed syllables are shown as CVC, open syllables CV. Some languages like English have many kinds of closed syllables. Some languages like Japanese have few kinds of closed syllables.

There are many words in English that have only one syllable.

  • Cat
  • House
  • The
  • Like
  • Run

There are many more words that have two or more syllables.

  • River (2 Ri-ver; CV-CVC)
  • Doctor (2 Doc-tor; CVC-CVC)
  • Happy (2 Hap-py; CVC-CV)
  • Computer (3 Com-pu-ter; CVC-CV-CVC)
  • Beautiful (3 Beau-ti-ful; CV-CV-CVC)
  • Pronunciation (5 Pro-nun-ci-a-tion; CV-CVC-CV-V-CVC)

Some languages do not use an alphabet with letters. Instead, each sign may stand for a syllable. For example: Japanese can be written using Kana.
