This book is intended for use in a course on linguistics for students who, having had some introduction to the field, wish to consider the ways in which linguistic theory can be applied to the practical matter of contrasting languages. The intention is to present some of the contemporary themes of linguistics to advanced students who eventually may have the need to implement them in language teaching or in designing new instructional programs. Chapters included in the book cover developments in contrastive analysis, theory and procedures, multidimensional aspects of language design, syntax, semantics, lexicon, phonology, and contrastive analysis and the foreign language teacher.
