This is the homepage of Lexical-Realizational Functional Grammar (LRFG), a project started by Ash Asudeh and Dan Siddiqi. Here you can download papers and presentations about the theory, as well as find out about the group of collaborators and students who are or have been involved with the project. The main work in progress currently is Constraint-Based Morphosyntax, a monograph to be published by Cambridge University Press in their blue series, Cambridge Studies in Linguistics.

LRFG is the result of an unlikely marriage between Distributed Morphology (DM) and Lexical-Functional Grammar (LFG). It shares traits of both its parent frameworks. Like LFG, it is a declarative, representational and constraint-based theory that is well-suited to modelling nonconfigurationality. Like DM, it provides a realizational, morphemic view of word-formation and is good at modelling complex morphological structures including those found in polysynthetic languages and other languages that display significant morphological complexity.
