The strict separation of syntax and morphology along with the rejection of derivational operations in structural syntax are two of several principles in contemporary lexicalist theories. The syntactic theory ofLexical-Functional Grammar (LFG) recognizes that this separation between syntax and morphology applies only to a structural domain but also that both are equal, interacting, and competing contributors in a functional domain.This book discusses the role of morphology in LFG, reintroducing two seminal papers on the impact of the development of LFG on morphology, while presenting new papers on current morphological issues. Theoretical issues addressed include the relationship between synthetic and analytic exponents of functional features; the need for a separate projection of m-structures; the nature of morphosyntactic paradigms; optimality theory's role in LFG morphology; and the use of LFG architecture in morphological description.
