The last few years have seen a steadily increasing interest in constructional approaches to language contact. This volume builds on previous constructionist work, in particular Diasystematic Construction Grammar (DCx G) and the volume Constructions in Contact (2018) and extends its methodology and insights in three major ways. First, it presents new constructional research on a wide range of language contact scenarios including Afrikaans, American Sign Language, English, French, Malayalam, Norwegian, Spanish, Welsh, as well as contact scenarios that involve typologically different languages. Second, it also addresses other types of scenarios that do not fall into the classic language contact category, such as multilingual practices and language acquisition as emerging multilingualism. Third, it aims to integrate constructionist views on language contact and multilingualism with other approaches that focus on structural, social, and cognitive aspects. The volume demonstrates that Construction Grammar is a framework particularly well suited for analyzing a wide variety of language contact phenomena from a usage-based perspective.
