Lexical-functional grammar, usually referred to as LFG, is a theoretical approach to syntax and related components of grammar originally developed in the late 1970s by Joan Bresnan and Ronald Kaplan. Conceived within the general program of generative linguistics, LFG differs from other such approaches in several respects. Unlike mainstream approaches within generative linguistics, LFG is a lexicalist, non-derivational, non-transformational framework. Unlike even most other non-derivational frameworks, LFG envisions syntactic description as focusing on Grammatical Functions rather than Constituent Structure, although constituent structure is also part of LFG syntax. LFG syntax thus includes two distinct dimensions of representation: c-structure (a surface constituent structure) and f-structure (a representation of surface grammatical functions). LFG has been applied to the analysis of a wide range of Syntactic Constructions in a wide variety of languages. In addition, it has a well-developed Formalism and has been used extensively in work in Computational Implementations.
