It has sometimes been pointed out in the generative literature that a semantic restriction is imposed on depictive predicates: stage-level predicates are acceptable as depictive predicates, but individual-level predicates are not. In this paper, we argue that as an answer to the question of why such a restriction is imposed on depictive predicates, Maruta's (1995) explanation is basically correct, but that the status of depictive predicates is not as simple as he supposes: they are, so to speak, half-fledged adverbials with adjectival nature rather than fullfledged adverbials. We therefore present an analysis which can provide an adequate account for such peculiar status.*
