Inflection class interactions and valency changes in Matlatzinca

In this paper, we explore how changes in the inflection class membership of verbs in Matlatzinca (Oto-Pamean, Oto-Manguean, Mexico) lead to changes in both their valency and meaning. In Matlatzinca, verbs often exhibit multiple class membership so that a given verb may be inflected as transitive in one class but as intransitive in another. For instance, the verb chun+ta , when inflected in different classes, can encompass diverse meanings: the action of ‘waking someone up’; the result state of ‘being awake’; and the spontaneous event of ‘waking up’. This linguistic phenomenon is intriguing from both a typological and a theoretical perspective as it challenges our understanding of lexical representation by prompting the question of whether these meanings represent distinct lexical entries or various construals of the same verb ( Spencer 2013 ).
