The Cree verbs ashteew(ak) 'it/they is/are found, it is (located)' or ayaweew(ak) 'is, are' are almost always used.
Rarely French ili 'he/she/it is' is used.
Iyave/ilave 'there was' (originally: French il y avait 'he had there') is used as well.
The stem ayaaw- can both mean 'to be' and 'to have'. This is probably the most common for the existential meaning and predicative possession alike.
