This book is a guide to the most important structures of Hungarian. It is a practical reference grammar intended to help the reader/learner in individual or group study, and can be used at all levels (beginner, intermediate, advanced). As the multitude of word forms presents perhaps the most serious challenge to those who study Hungarian, the focus of the book is the way in which words are built up from stems and affixes including inflection and derivation (word formation). In addition to a comprehensive treatment of the regularities and irregularities of word structure, the book covers pronunciation, letter-to-sound correspondences, the essential characteristics of larger structures (such as phrases, clauses and sentences), and gives detailed information on usage. As an especially user-friendly feature, the book contains an index of words which cross-references all the words discussed in the grammar which are irregular or behave in a special/notable way in some, respect. The book also has a subject index and an index of derivational affixes.
