Practical English Usage has sold over 2 million copies worldwide. Now revised and updated for the fourth edition, it answers the questions that teachers and learners ask about English grammar and vocabulary with clear, corpus-informed explanations and examples.

With this dictionary students learn the most important collocations they need to know. The dictionary also guides them to the right word combination for their context. The CD-ROM includes the complete dictionary and practice exercises.

The word combinations are based on analysis of the Oxford English Corpus, a collection of three billion words of text from the English-speaking world that show the words that really do go together.
