From grammaticalization to Diachronic Construction Grammar


The term grammaticalization originally denoted a particular outcome of language change (lexis > morphology), then got expanded to practically all studies involving language change, the processes that create such changes, and a theory modeling these. These expansions have been challenged in the literature as conceptually flawed. A usage-based analysis of the evolution of the concept culminates in the use of the term grammaticalization as a “flag” of a particular approach to linguistics. However, the theoretical premises of grammaticalization studies are entirely compatible with the premises of Diachronic Construction Grammar (DCxG). All studies within the “expanded” concept of grammaticalization can be explicitly modeled within DCxG, which provides formalism of sufficient detail to map the gradual nature of language change in cases of grammaticalization and beyond. Consequently, the most vigorous attacks on grammaticalization lose power when grammaticalization is seen as part of a larger, more complete theory of language and language change.
