Functional-cognitive linguists are typically more interested in what is shared between grammar and other aspects of language than in what is special about grammar. Construction grammar as the currently most prominent functional-cognitive theory of grammar explicitly downplays the grammar-lexicon distinction and suggests a model based on the notion of ‘constructicon’ as a unified inventory of linguistic expressions. In a neurocognitive perspective, this goes naturally with the idea of a single processing mechanism. Neurolinguistic evidence does not support this extreme position, however, but rather suggests a significant difference between lexical and grammatical processing. There is thus a need for a more well-developed functional-cognitive theory of the neurocognitive underpinning of the grammar-lexicon distinction. In this chapter we present a theory of the specific nature of grammar, which integrates three recent theories: a usage-based linguistic theory of the grammar-lexicon distinction (Boye & Harder 2012), a theory of the distinction between declarative and procedural memory (Ullman 2001, 2004), and a theory of brain organization (Mogensen 2011).
