Local and non-local consonant–vowel interaction in Interior Salish*

Local consonant–vowel (C–V) interaction is attested in many languages, both as a phonetic and as a phonological process. There can be a clear developmental relationship between the two, with phonologisation of phonetic interaction occurring quite commonly (Hyman 1976, Ohala 1981). Thus, a common (historical) context for nasal vowels is an adjacent nasal consonant. When consonants trigger non-local effects (i.e. when the domain of the consonantal feature extends beyond adjacent segments), typically both vowels and consonants are targeted. For example, in consonant-induced nasal or emphasis harmony all segments in the harmony domain usually take the consonantal feature. If some segments are neutral, targets still include both consonants and vowels.
