A study examines various Huastec clause types that are reflexive in some sense, including ordinary reflexives, which involve co-reference. Two mutually exclusive morphosyntactic devices are used in Huastec: reflexive pronouns and verbal morphology. In this way, Huastec is like various European languages. Clauses involving reflexive pronouns and verbal morphology are considered separately. The analysis adopts the frameworks of relational grammar and arc pair grammar together (AG). The analysis assumes basic familiarity with the two frameworks, although some details of the formalisms are introduced as appropriate. The manner in which reflexive clauses and co-reference are treated within AG is outlined and the two clause types are discussed in detail. In the case of clauses involving reflexive verbal morphology, four types are examined, including: ordinary reflexives, reflexive passives, reflexive unaccusatives, and reflexive antipassives. A brief list of references is included. (MSE)
