Abstract

Grammatical information in ASL can systematically be marked on the face. Such nonmanual marking extends over the c-command domain of the trigger, and therefore provides information about the hierarchical organization of the language. Consistent with evidence available from the distribution of non-manual markings—as illustrated with respect to wh-marking and negation—a basic clausal structure for ASL is proposed. Furthermore, we suggest, contrary to generally accepted claims about ASL, that both Tense and Agreement are structurally present in all ASL main clauses. This analysis allows for a uniform account of the licensing of null subjects in ASL. Evidence in favor of this analysis, and against a dual licensing mechanism (as proposed in Kegl, 1985, and Lillo-Martin, 1986, 1991b), is presented.
