Tittle: Dedicated de re attitude reports
Date/Time: Thursday, December 1/12:30pm-1:50pm

Indefinites occurring in attitude complements can typically be read either de dicto or de re. This choice is commonly treated as a true ambiguity, involving two separate sets of truth conditions corresponding to two distinct LFs, rather than (say) as a case of generality or underspecification based on a single LF. Is the ambiguity approach the correct one? In particular, are there LFs in which indefinites occurring in attitude complements must obligatorily be construed de re? I argue that there are indeed. My argument comes from Nez Perce attitude reports in which the attitude verb shows apparent long distance agreement with a DP inside the attitude complement. This DP must be read de re. The de re reading, I argue, derives from an LF in which the res argument moves into the matrix clause covertly; that is, Nez Perce manifests a (syntactically well-behaved) version of res-movement. Notably, there does not exist an equally syntactically distinguished variety of attitude reporting reserved for de dicto readings. Indefinites that may be read de dicto in Nez Perce may also typically be read de re, without morphosyntactic consequences, as in English. I suggest, then, that the true ambiguity at the level of LF may be between a dedicated de re LF and an LF which is general enough to support either de re or de dicto attitudes.
