If you’re trying to achieve a good command of fluency-relevant vocabulary, a conventional thesaurus won’t be of much help — no matter how helpful it may be for other purposes. This is so whether it’s a Roget-style thesaurus or a dictionary-style thesaurus.

To achieve a good command of fluency-relevant vocabulary, you need dedicated fluency-oriented vocabulary building books — books that focus on fluency-building vocabulary.

And the Core Fluency Thesaurus is a dedicated fluency-oriented vocabulary building book — and the first thesaurus of its kind. From none other than Prof. Kev Nair, the world’s foremost authority on fluency building. And it groups together, under headwords, word groups that express meanings similar to, or somewhat similar to, its important meanings. These are groups of words that individual words tend to form with other words, with a more-than-chance frequency: Phrases, collocations, phrasal verbs, idioms and other multi-word items that have the property of adding to your fluency. The author has marked how relatively frequent/important (for fluency training) a headword is with the indicators ‘AAA’, ‘AA’ and ‘A’. Headwords marked ‘AAA’ are more frequent/important than those marked ‘AA’ and ‘A’. And headwords marked ‘AA’ are more frequent/important than those marked ‘A’.

If you’re an advanced user of English – someone who has to make heavy use of fluent English in his/her everyday life – you need this book.
