Clusivity and the history of personal pronouns in East Caucasian

Abstract Personal pronouns are among the most stable lexemes in the East Caucasian family, which consists of at least forty different languages distributed over eight well established branches, with nevertheless important variations and paradigmatic reshaping across branches, languages, and even dialects. The 1st and 2nd singular pronouns have been replaced or changed shape at least once in many subparts of the family, and the main 1st person singular innovation was apparently followed by areal spread. Most languages retain two different pronouns for the 1st person plural European pronoun, but the cognates are not always clear, suggesting that although clusivity is an inherited feature of East Caucasian pronominal paradigms, its history is complex, with various types of loss and renewal. This paper attempts to draw a fine-grained and accurate picture of these 1st person plural pronouns and their history within the larger setting of personal pronouns in general. Most individual stories behind variation across branches, languages and dialects provide reasons to see inclusive pronouns as prone to be maintained or renewed over time, whereas exclusive pronouns (1st person singular or plural) are specially targeted by avoidance and replacement processes.
