Syllable(redirected from decasyllabic)
Also found in: Dictionary, Thesaurus.
the minimal articulated unit of speech, consisting of one or several sounds that form a compact phonetic entity and that occur during one chest pulse. Proponents of various theories concerning the syllable believe that a syllable is produced by one muscular contraction, by modulation (narrowing and widening) of the pharynx, or by the degree of sonority and the order in which sounds are uttered.
A syllable is composed of a beginning (onset), a peak (nucleus), and a final part (coda). A peak is formed by simple vowels (ma-ma), by sonorants in some languages (Czech prst, “finger”), and occasionally by obstruents (psst!). A syllable’s beginning and end are formed by one or more consonants; in some languages a syllable may consist only of a peak (o-ni, “they”). Syllables are closed when they end in a consonant and open when they end in a vowel. They are uncovered when they begin with a vowel and covered when they begin with a consonant. The commonest syllable structure, found in all languages of the world, is consonant followed by vowel.
Division into syllables often does not correspond to division into morphemes. In the word ruchka (“handle”), morphemes for example, there are two syllables (ru-chka) but three morphemes (ruch-k-a). In syllabic languages, such as Chinese, morphemes are generally monosyllabic and syllable and morpheme boundaries coincide. In such languages, the beginning of a syllable is contrasted to its end, which is limited to certain permissible sounds.
