Lexical-Functional Grammar is a lexicalist, nontransformational theory of grammar which is built on a powerful and mathematically well-defined grammar formalism, designed for typologically diverse, configurational and non-configurational languages. LFG models different levels of linguistic description in a functional correspondence architecture. C-structure encodes constituency and surface order, which radically differ across typologically distinct languages. F-structure encodes functional syntactic information, which is largely shared between typologically distinct languages. LFG grammars are declarative, and therefore reversible for generation.
