Practical English Usage Fourth Edition, Michael Swan Oxford University Press, 978-0-19-420243-5
Most English language teachers have checked tricky grammar points in this well-known book, which is both a usage guide and a learner’s grammar. The key change in this fourth edition is the replacement of the alphabetical organisation by a thematic arrangement. So, grammatical entries are grouped into 28 sections; this topic-by-topic organisation works well. Vocabulary problems are dealt with in a further three sections. Entries contain an explanation of a problem, corpus-informed examples of correct usage and where appropriate, examples of student mistakes. With fascinating entries on newspaper headlines, language change and varieties of English, this comprehensive book remains indispensable.
