This paper presents an analysis of the meanings and uses of two reflexive morphemes in the Mohawk language. Reflexive "atat" is shown to have both reflexive and reciprocal meanings. It is also realized in kinship terms and in the transitive pronominal prefix "yutat." Semi-reflexive "at" has some reflexive functions, and can mark middle voice and detransitivized states or processes. Additional uses of "at" are also examined. The paper concludes with a discussion of comparative data on reflexives in other Iroquoian languages. Contains 30 references. (MDM)
