This is a clear and user-friendly guide to Persian grammar, both of the written and spoken languages, especially useful for those in the early stages of studying the Persian language. It serves as a revision and reference book that can be used to support any Persian course book. The script is taught step-by-step. It uses the official reformed spelling, and gives attention to handwriting, educated standard and educated colloquial pronunciation, and the important polite forms. The grammar is explained in lay terms with copious examples, all shown both in Persian script and in Roman transliteration. The grammatical themes are grouped logically, and there are cross-references, appendices and a subject index to facilitate the search for the right form.
