Cognitive grammar
[4] Volume one is titled "Theoretical Prerequisites", and it explores Langacker's hypothesis that grammar may be deconstructed into patterns that come together in order to represent concepts.Langacker invites his reader to utilize the tools presented in the first volume of Foundations in a wide range of, mainly English, grammatical situations.It primarily diverges from Chomskyan tradition through its assertion that grammar and language are integral and essential parts of cognition, not merely autonomous processes in the brain.[6] Langacker argues not only that cognitive grammar is natural by virtue of its psychological plausibility, but also that it offers conceptual unification and theoretical austerity.[7] It considers the basic units of language to be symbols (i.e. conventional pairings of a semantic structure with a phonological label).
