Cognitive grammar is a comprehensive and unified theory of linguistic structure, denying, despite its emphasis on conceptualization, the existence of any sharp or specific boundary between pragmatic and linguistic considerations. It is in fact a pragmatically grounded theory of language in regard to its organization, its view of semantics, and even its account of grammar. The organization it ascribes to a linguistic system directly reflects language's basic semiological function. It further adopts an encyclopaedic view of linguistic semantics, and claims that it is characterized by partial (rather than full) compositionality.
