On one view of syntactic structure, the expression of the grammatical relation subject is associated with an NP position. On another, this grammatical relation is expressed by a bound pronominal form. Discussion of the choice of one or the other of these has focused exclusively on the reflex of what is traditionally termed ‘subject/verb agreement’ and an ‘agreeing’ NP. This paper offers a theory, exemplified through an analysis of Luiseño, which accommodates a range of ‘subject agreement’ forms. The analysis is based on the idea that subject information can flow from a number of distinct sources. Languages might differ in regard to how many of these sources are used. One consequence of this idea is to deny a simple bifurcation into subject-pro-drop / non-subject-pro-drop or pronominal-subject / nominal-subject languages. The Luiseño analysis, therefore, forces a reconsideration of the roles of subject/verb agreement and the agreeing NP in grammatical composition.
