Reflexive in Tyvan

Tyvan reflexive voice has a seemingly wide range of use. This paper divides the Tyvan reflexive into two uses: reflexive and anticausative. This classification is not only based on the semantic properties of the reflexive but also corresponds to its morpho-syntactic behaviors. In reflexive use, the reflexive suffix can be attached to an intransitive stem,and the clause may have an accusative NP as its direct object. The derivative verb is not semantically predictable from the base, since it covers non-prototypical meanings such as "patientless" and "possibility." In anticausative use, in contrast, the reflexive suffix cannot be attached to an intransitive stem, and the clause never has an object in the accusative case. The resultant verb is semantically quite transparent, and its meaning is highly predictable based on the base verb. The two uses are also different when it comes to possibilities of derivational morphology: a volitional, an actor nominal, or a causative suffix can follow the reflexive suffix in reflexive use, while a potential suffix can follow the reflexive suffix in anticausative use.
