Weight

1)音重

2)輕重

 

(1) In phonology, a concept used to distinguish levels of syllabic prominence, based on the segmental constituency of syllables. Syllables can be metrically heavy (H) or light (L): a light (or ‘weak’) syllable is one whose rhyme comprises a short-vowel nucleus alone or followed by a coda of no more than one short consonant (in terms of phonological length, a mora); a heavy (or ‘strong’) syllable is any other type (its phonological length being greater than one mora). Syllables of structure CVVC or CVCC are sometimes referred to as ‘superheavy’. The notion of weight has also come to be important in several models of non-linear phonology.

(2) In syntax, a concept which relates the relative length/complexity of different elements of sentence structure. For example, a clause as subject or object would be considered heavier than a lexical noun phrase, which would be heavier than a pronoun. Such variations in length and complexity seem to influence the order of elements in languages: for example, there is a preference for short > long linearization in right-branching (VO) languages, and for long > short in left-branching (OV) languages.

 

(1)音系學術語,根據音節的音段組構區分音節突顯的不同程度。音節在節律上可重可輕:輕(或“弱”)音節是韻基只由一個短元音韻腹或后接一個不超過一個短輔音的韻尾組成的音節(音系學上的音長為一個莫拉);重(或“強”音節)是任何其他類型的音節(音系學上的音長不止一個莫拉)。結構為CVVC或CVCC的音節有時稱作“超重”音節。音重已成為非線性音系學多種模型的一個重要概念。

(2)句法概念,指句子結構不同成分的相對長度/復雜性。例如,由小句充當的主語或賓語被認為比由詞匯名詞短語充當的重,后者又比由代名詞充當的重。這種長度和復雜性的差異看來影響語言中成分的序次:例如,右分叉(VO)語言有短>長的線性化傾向,而左分叉(OV)語言有長>短的線性化傾向。
