English Words: History and Structure is concerned primarily with the learned vocabulary of English, the words borrowed from the classical languages and French. It is both an introduction to some of the basic principles of linguistic analysis and a helpful manual for vocabulary discernment and enrichment. Designed to deepen and strengthen the knowledge acquired in the classroom, exercises to accompany each chapter and further readings on recent loans and the legal and medical vocabulary of English are available online at http: //uk.cambridge.org/linguistics/resources/englishwor ds.
