Diachronic construction grammar and grammaticalization theory

Abstract

Grammaticalization theorists are becoming increasingly aware of the relevance of constructions to their discipline, to the point that one of its leading exponents has recently defined grammaticalization as the creation of new constructions. This is precisely the problem which construction grammarians engaging in diachronic research are addressing - or one they should be addressing, because to date diachronic construction grammar has not really taken off as a discipline. The question arises of whether grammaticalization theory could simply be turned into the historical branch of construction grammar, or whether diachronic construction grammar has its own raison d'être as a separate discipline. Since grammaticalization theoretical practice is fairly narrowly focused on the change of extant constructions along a path towards the grammatical end of the meaning continuum, there is a need for a wider discipline that also concerns itself with the primary emergence of constructions. Though grammaticalization presupposes 'constructionalization, the two developments need to be kept apart because not all constructions go on to grammaticalize. © John Benjamins Publishing Company.
