This book is primarily intended for B.A. students in Hungarian higher education training to become teachers of English. It includes much less theory - i.e. much less "linguistics" - than a standard university textbook would, and much more practical material, thought to be helpful for the future teacher. As a practical textbook for Hungarian teacher trainees, it gives linguistic arguments only as background when necessary. It does not contain much of the phonological argumentation that is normally required at university level. The treatment is selective: it concentrates on the difficulties of Hungarian learners, while it often ignores things that are not important from a Hungarian point of view.
