This course explores the basic principles governing word structure and their interaction with phrasal and clausal syntax. Goals include: examining the evidence for taking morphemes to be syntactically independent units; introducing the mechanisms by which morphemes are combined and ordered, using the formal tools made available to us by Minimalist syntax and Distributed Morphology; and investigating cases in which syntactic structure and prosodic requirements conflict. The course will draw on evidence from diverse languages to examine phenomena such as morpheme ordering, blocking, and instances of morphosyntax-morphophonology non-isomorphisms (bracketing paradoxes, prosodic effects).
