Two instances of unaccusative verb mismatches in Japanese are examined. An unaccusative mismatch is the situation in which a different accusative diagnostic singles out different classes of intransitive verbs within and across languages. One type of unaccusative mismatch has to do with group C verbs, or verbs of manner with protagonist control. When these verbs occur with a goals phrase that allows the verb to express inherent direction of motion, they can appear in the unaccusative syntactic configuration. The other instance occurs in the "TE ARU" construction within group A verbs. However, this kind of mismatch can be attributed to different representation in lexical conceptual structure. It is further observed that group A and group B verbs, both of which are unaccusative, are basically rejected in the construction because the agentive interpretation is suppressed within these verbs. It is concluded that inherent direction and lack of protagonist control are significant properties that point toward characterization of unaccusativity. (Contains 19 references.) (MSE)
