Editing Koasati language (section)

===Syllable structure===
Koasati has both light (CV, VC, V) and heavy (CVC) [[Syllable weight|syllables]]. Consonant clusters occur across syllables but not within. All monomorphemic Koasati words end in light syllables, while the penultimate syllable can be light but is usually heavy, and it is usually preceded by one or more light syllables, as with the construction CV.CVC.CV as in the word ''holihtá'' "fence". Other shapes, in which one or more heavy syllables precede a heavy penultimate syllable (e.g. CV.CVC.CVC.CV as in ''hacokpalpá'' "butterfly"), or alternate heavy and light syllables (e.g. CVC.CV.CVC.CV. as in ''pa꞉piyá꞉ka'' "bridge"), are usually the result of the compounding of two words or a once-productive rule of [[Syncope (phonetics)|syncope]] in which the vowel of every second syllable except the final syllable was deleted. Vowel clusters occur in Koasati, unlike in other Muskogean languages where such clusters are made impossible by [[Metathesis (linguistics)|metathesis]] and vowel deletion. These clusters occur in Koasati due to the use of locative prefixes that end in a vowel and class 1A negative transitive verbs since these do not undergo the processes of metathesis and vowel deletion. Clusters beginning with /a꞉/ and /i꞉/ are most frequent, and all clusters are generally spoken with a glottal stop between vowels.
