This collection of new work focuses on issues at the lexicon-syntax interface. It presents innovative analyses of theoretical issues of aspectual interpretation in a variety of languages. The authors address questions such as to what extent can variation in verbal meaning, and thematic information can be determined in the syntax, and how the interpretation of various syntactic constructions is derived, once lexical information is minimized. A subset of the articles develops theories that take as their starting point the lexical-syntactic framework of the late Ken Hale and Jay Keyser, prominent among which is their own chapter.
