A Dictionary of Stylistics (Studies in Language and Linguistics)

I bought this book as a supplemental reference for the Open University course E301 The Art of English. However I also found it very useful for U211 Exploring the English Language.

It contains plenty of otherwise hard-to-find entries that are well-worded and explained. This dictionary is just the thing if you want a handy and comprehensive reference to key terms and concepts of stylistics.

Expensive, but worth the money.
