Polinsky, MariaPreminger, OmerPartial funding for Open Access provided by the UMD Libraries' Open Access Publishing Fund.In this paper, we propose a new generalization concerning the structural relationship between a head that agrees with a DP in φ-features and the predicate that assigns the (first) thematic role to that DP: the Agreement Theta Generalization (ATG). According to the ATG, configurations where the thematic-role assigner is located in a higher clause than the agreeing head are categorically excluded. We present empirical evidence for the ATG, discuss its analytical import, and show that this generalization bears directly on the proper modeling of syntactic agreement, as well as the prospects for reducing other syntactic (and syntacto-semantic) dependencies to the same underlying mechanism.en-UStheta-role assignmentagreementlong-distance agreementcross-clausal dependencyfeature valuationArticle
