Derivational Verbal Suffixes in Abaza

This paper describes a group of derivational verbal suffixes in Abaza, a polysynthetic language belonging to the Northwest Caucasian family. For each suffix I propose a short description of its most remarkable features. In particular, I discuss the polysemy of the refactive and assertive markers and their interaction with the event structure of the verb. Other suffixes such as the putative and inferential markers are interesting due to their peculiar morphological behavior. The diversity of the discussed affixes is tentatively explained by the different pathways of their morphological and semantic development
