Malagasy clause structure and language acquisition

We argue that Malagasy (and related W. Austronesian languages!) has a positive setting for a macro-parameter RICH VOICE MORPHOLOGY which builds complex predicates that code the theta role of their argument: S = [[PreN(6) + (X)] + DP]. Manifestations of this parameter are: (1) Case and theta role are assigned in situ in nuclear clauses with no movement or co-indexing to a topic position. (2) Relative Clauses (and other "extraction" structures) satisfy the "Subjects Only" constraint, again with no movement or indexing. (3) UTAH is freely violated, as theta role assignment derives from compositional semantic interpretation. Predicates resemble lexical Ns in assigning case directly to arguments without using Prepositions and in combining directly with Dets to form DPs that include tense and negation (Keenan 1995, 2000). The major Predicate-Argument type is modeled on the Noun+Possessor one, not the Verb+Object one.
