This book is the first truly comprehensive study of Igbo-English intrasentential code-switching set against the backdrop of the Matrix Language Frame model. As such, its a landmark in our understanding of language contact phenomena which is bound to become an increasingly hot topic as migration from areas like West Africa to Europe reaches new heights. -- Karen Corrigan, Professor of Linguistics and English Language, Newcastle University, UK This is a major contribution to language contact scholarship in particular and sociolinguistics in general. The discussions in the monograph benefit richly from insider understanding not only of the structures of Igbo language but also of the complex dynamics of Igbo interaction with English in multilingual contexts. Ihemere's lucid writing will endear readers to the work. -- Tope Omoniyi, Professor of Sociolinguistics and Director of the Centre for English Language and Linguistics, University of Roehampton, UK
