Towards a typology of middle voice systems

The middle voice is a notoriously controversial typological notion. Building on previous work (e.g. Kemmer, Suzanne. 1993. The middle voice. Amsterdam & Philadelphia: John Benjamins), in this paper I propose a new working definition of middle markers as inherently polyfunctional constructions which are partly associated with valency change in opposition to bivalent (or more) verbs and partly lexically obligatory with monovalent verbs. Based on this definition, the paper undertakes a systematic survey of 149 middle voice constructions in a sample of 129 middle-marking languages. Evidence from the sample shows that middle voice systems display a much richer variation in forms and functions than is reported in the literature. This richer empirical evidence challenges some of the mainstream views on middle marking, especially its purported connection with reflexivity and grooming-type events, and calls for an overall rethinking of the typology of the middle voice.
