The structure of the noun phrase (NP) in Alsea, an extinct language of the Oregon coast, is examined with particular attention to the behavior of a clitic occurring in second position within the NP. A presentation of the basic facts includes the following: referential(s) and the deictics, possessive pronouns, third-person possessive, the ergative, modifiers, and the dative morpheme. A formal analysis is then provided, although because it is based on incomplete data limited by the contents of the available texts, certain issues cannot be resolved definitively. The analysis covers Klavens' parameters, the basic structure of the noun phrase, and the clitics. It is concluded that dative is lexically marked so that the preposition is forced to move to the end of the clitic group. Contains 11 references. (LB)
