Over the last decade, Construction Grammar has become increasingly popular in the study of language contact and multilingualism. Indeed, constructional approaches, including Diasystematic Construction Grammar, not only offer a useful theoretical framework for empirical studies, but also provide a fresh look at fundamental questions in contact linguistics. This volume continues the series of works on Constructions in Contact (the first two volumes were published in 2018 and 2021). It presents new research on the constructionist modelling of language contact phenomena, the impact of multilingualism on argument structure constructions and the role of phonological units in language contact. The volume thus combines classical areas of constructional research with innovative ones, demonstrating the broad applicability of Construction Grammar for contact linguistics.
