Syllable structure

A Khmer syllable begins with a single consonant, or else with a cluster of two, or rarely three, consonants. The only possible clusters of three consonants at the start of a syllable are /str/, /skr/, and (with aspirated consonants analyzed as two-consonant sequences) /sth/, /lkh/. There are 85 possible two-consonant clusters (including etc. analyzed as /ph/ etc.). All the clusters are shown in the following table, phonetically, i.e. superscript ʰ can mark either contrastive or non-contrastive aspiration (see above).

Slight vowel epenthesis occurs in the clusters consisting of a plosive followed by /ʔ/, /b/, /d/, in those beginning /ʔ/, /m/, /l/, and in the cluster /kŋ-/.

After the initial consonant or consonant cluster comes the syllabic nucleus, which is one of the vowels listed above. This vowel may end the syllable or may be followed by a coda, which is a single consonant. If the syllable is stressed and the vowel is short, there must be a final consonant. All consonant sounds except /b/, /d/, /r/, /s/ and the aspirates can appear as the coda (although final /r/ is heard in some dialects, most notably in Northern Khmer).

A minor syllable (unstressed syllable preceding the main syllable of a word) has a structure of CV-, CrV-, CVN- or CrVN- (where C is a consonant, V a vowel, and N a nasal consonant). The vowels in such syllables are usually short; in conversation they may be reduced to, although in careful or formal speech, including on television and radio, they are clearly articulated. An example of such a word is មនុស្ស mɔnuh, mɔnɨh, mĕəʾnuh ('person'), pronounced, or more casually.
