The φ-features – person, number, and gender – connect morphology, syntax, and semantics in an interesting way. Assumptions about φ-features in one component of grammar almost always have repercussions for the other components of grammar. In this paper, I primarily develop a proposal for the semantics of φ-features, namely the Presuppositional Approach. But I also aim to develop an explicit syntactic and morphological analysis that is compatible with my semantic proposal.
