 Front-vowel apocope fails to occur in locatives, verbal negatives, many historical locative/ergatives, and a number of i-final stems such as "wan̪t̪alŋi" 'a species of fish'.Back-vowel apocope also has lexically-governed exceptions.Cluster reduction simplifies underlying word-final consonant clusters, as in "*makark" > "makar" 'anthill'.
