This volume is an inspiring example of the capacity of constructional approaches to deal with complex linguistic data and theoretical problems. The papers united here apply constructional models to tackle unsolved questions in language contact and other multilingual constellations like second language acquistion and additional language acquisition. Taking up what has been achieved in the field of language change, the scope of constructional models is expanded to the investigation of diasystemic constructions. A highly welcome and instructive read to everybody interested in the field!

Generally, the volume presents a significant contribution to the area in several major ways. Firstly, it analyses language contact phenomena in a range of typologically different languages, as well as in a deaf sign language, not addressed before. Secondly, in addition to classic language contact, it also analyses multilingual practices and additional language acquisition as emerging multilingualism, also largely overlooked before. And thirdly, the obtained results testify to the validity and explanatory potential of DCxG both alone and in combination with other approaches.

This terrific volume calls attention to the importance of language contact in shaping the constructicon. The expert contributions showcase research which displays a number of interactions with other domains of enquiry in Construction Grammar. The book addresses numerous topics in multilingualism, drawing on an impressively diverse range of language families. It will be of tremendous interest to anyone interested in usage-based approaches to linguistic diversity.
