Culture in a radically usage-based model of language change, with special reference to constructional attrition

This article offers theoretical and programmatic reflection on how the impact of culture on language change should be accounted for from a radically usage-based diachronic construction grammatical perspective, with a focus on how cultural change can cause constructions to disappear from a language. It approaches this question through an assessment of how culture is incorporated in Schmid's (2020) Entrenchment-and-Conventionalization model of 'the dynamics of the linguistic system'. Against the backdrop of various proposals on the effect of 'democratization' in Anglo-Saxon culture on subtractive historical developments in the modal domain of English, and based on a study of interpersonal variation in the intrapersonal longitudinal development of a declining modal construction, the paper argues that the influence of culture on language change is mediated by entrenchment and that culture has a more extensive impact on entrenchment than the EC-model currently allows for.
