Phonotactics
The ultimate syllabic structure is C(C)V(V)(C), and all lexical words contain 1-3 syllables.

No consonant clusters of more than two consonants are allowed. Affricates, aspirates, and nasalised clicks count as a single consonant in this analysis. Nasalised vowels may not appear in a diphthong with an oral vowel.
