In words of French origin, the phoneme is found word-initially (sarvaan 'house-keeper'), word-medially (pwesoon 'fish') and word-finally (pjas 'dollar').
In words of Cree origin, the phoneme /s/ is only found in clusters s + stop (as in wapasteen '(s)he sees it') as variants used by some speakers for the pre-aspirated stops: other speakers say waapahteen. Thus, in Cree words it only exists for some speakers, and only in very specific environments.
