Shokitin: Nominal Categories: Plurality in Independent Personal Pronouns: Person-number stem
There is not uniformity in the derivation of personal pronouns. Plurality in the first person is indicated by stem change; the first person has exclusive and inclusive forms, neither of which are derived from the singular. The second person pronoun has a person stem from which a plural is derived using the nominal suffix. Atypically, the same is true for the third person pronouns as for the second person pronouns.
