Grammatical Framework (GF) is a programming language for writing grammars of natural languages. GF is capable of parsing and generating texts in several languages simultaneously while working from a language-independent representation of meaning. Grammars written in GF can be compiled into different formats including JavaScript and Java and can be reused as software components. A companion to GF is the GF Resource Grammar Library, a reusable library for dealing with the morphology and syntax of a growing number of natural languages.
Both GF itself and the GF Resource Grammar Library are open-source. Typologically, GF is a functional programming language. Formally, it is a type-theoretic formalism based on the Martin-Löf type theory.

Famous quotes containing the words grammatical and/or framework:
“Speech and prose are not the same thing. They have different wave-lengths, for speech moves at the speed of light, where prose moves at the speed of the alphabet, and must be consecutive and grammatical and word-perfect. Prose cannot gesticulate. Speech can sometimes do nothing more.”
—James Kenneth Stephens (1882–1950)
“The city is a fact in nature, like a cave, a run of mackerel or an ant-heap. But it is also a conscious work of art, and it holds within its communal framework many simpler and more personal forms of art. Mind takes form in the city; and in turn, urban forms condition mind.”
—Lewis Mumford (1895–1990)
