====Pronouns====
The personal pronouns exhibit partly suppletive allomorphy between the nominative and oblique stems; case endings are added to the latter:<ref name="Róna-Tas 1997: 4"/>

Demonstratives are ку 'this', çак 'this' (only for a known object), çав 'that' (for a somewhat remote object), леш 'that' (for a remote object), хай 'that' (the above-mentioned). There is a separate reflexive originally consisting of the stem in х- and personal possessive suffixes:

Interrogatives are кам 'who', мӗн 'what', хаш/хӑшӗ 'which'. Negative pronouns are formed by adding the prefix ни- to the interrogatives: никам, ним(ӗн), etc. Indefinite pronouns use the prefix та-: такам etc. Totality is expressed by пур 'all', пӗтӗм 'whole', харпӑр 'every'.

Among the pronominal adverbs that are not productively formed from the demonstratives, notable ones are the interrogatives хăçан 'when' and ăçта 'where'.
