Thomson and Martinet's classic grammar is the most widely used book of its kind.
It is popular because its explanations are clear and because it deals thoroughly
with the topics which students find most difficult. It is intended for
intermediate and post-intermediate learners, but is also a useful source of
reference for more advanced students and for teachers. A Practical English
Grammar has now been revised and reissued in a fourth edition. The text has been
rewritten in many places to bring it up to date. Some material has been
rearranged to make it simpler for the reader to compare related topics. There is
fresh or fuller treatment of many subjects, notably in the chapters on nouns,
adjectives, adverbs, prepositions, conjunctions, auxiliary verbs, the infinitive
and the passive. A new index contains many more entries and now includes
references to every important structural word. These changes, and an improved
design, make A Practical English Grammar more informative and easier to consult
than ever.
