The words for 'who' as interrogative (aweena from Cree) and the indefinite 'someone' (awiyak from Cree or quelqu'un from French) are clearly distinct. The Cree forms are pervasive, the French forms marginal.
The word keekway (with variant forms) is used both for 'something' and 'what'. Some speakers claim that their forms for 'what' and 'something' are different.
