English in this knowledge era is a language of opportunity, the currency of the future. There is understandably an all round demand for English and effective English teachers. A novice peering through ELT journals and textbooks is often baffled by the many technical terms and specialist jargons. There is no one book that can acquaint them with the major terms and issues connected with language learning. This Glossary responds to the needs of such learners, initiating them to the basics and providing them a sound grasp of the essentials the profession has come up with. A doctrinaire approach to the terms and concepts is not intended nor does the book include all nuances, every view, development and reaction. This is primarily a reference book for every learner, teacher and researcher in ELT. Related terms are clubbed together thematically so the reader can be made aware and widen his/her understanding of the developments in the field.
