“This is a highly engaging text that gives thorough coverage of all aspects of contact linguistics. The writing is clear and concise, and the book presents even complex issues in an entertaining and accessible style. Right from the beginning, Winford makes it clear that the field of study adopts an interdisciplinary approach that draws on theoretical linguistics and theories of second language acquisition, and that these theories are intertwined with sociocultural factors.” (Language Documentation & Conservation) "The volume's extensive, linguistically detailed coverage will make this a stimulating textbook for upper level students with good prior grounding in linguistics."
