Two Ways of Deriving Distributive Readings J.-R. Hayashishita This paper argues that there are two distinct ways to interpret sentences, and each way can derive distributive readings (DR); hence two kinds of DR's. A given sentence can always be interpreted directly based on its LF representation. If it is so interpreted, the relative scope of NP's is determined solely on the basis of their A-position c-command relation. When a given sentence is represented at LF in a particular way, it can be interpreted through an extra mechanism, Omega Predication (a special kind of Subject Predication). DR for NPi over NPj (DR ) is derived through Omega Predication only if the "value" of NPi is a Subject and NPj is incorporated into a verb. In support of this claim, it will be shown that when a sentence cannot be interpreted by means of Omega Predication, DR fails to obtain, although DR does not. Among the implications of this paper are (i) that QR in May 1977 is not necessary in deriving DR , and (ii) that the Scope Principle of Reinhart 1976 holds in the environments where a sentence must be interpreted solely on the basis of its LF representation. Keywords: distributive readings, quantifier raising, A/A'-position, Omega Predication.
