This new volume on language contact and contact languages presents cutting-edge research by distinguished scholars in the field as well as by highly talented newcomers. It has two principal aims: to analyze language contact from different perspectives - notably those of language typology, diachronic linguistics, language acquisition and translation studies; and to describe, explain, and elaborate on universal constraints on language contact. The individual chapters offer systematic comparisons of a wealth of contact situations and the book as a whole makes a valuable contribution to deepening our understanding of contact-induced language change. With its broad approach, this work will be welcomed by scholars of many different persuasions.
