Modular design of grammar: Linguistics on the edge presents the cutting edge of research on linguistic modules and interfaces in Lexical-Functional Grammar (LFG). LFG has a highly modular design that models the linguistic system as a set of discreet submodules that include, among others, constituent structure, functional structure, argument structure, semantic structure, and prosodic structure, with each module having its coherent properties and being related to each other by correspondence functions. The contributions in this volume represent the broad range and interconnection of theoretical, formal, and descriptive considerations that continues to be the hallmark of LFG.
