The Chambers Thesaurus sells more copies, and contains more synonyms, than any other English thesaurus. This 5th edition, new for 2015, retains the much-loved features of The Chambers Thesaurus, but also includes a brand new two-colour Word Lover's Ramble at the back, showing how English words and definitions have changed in recent years. The Chambers Thesaurus is now the UK's number 1 selling hardback thesaurus. It is regarded as the thesaurus of choice for crossword setters and solvers, and is popular with players of wordgames such as Scrabble(R) and Words With Friends(R). It is famous for its Scottish heritage, its thorough coverage of obscure words and its unique personality. "Chambers stands out like a baroque mansion in a city of faceless concrete." Melvyn Bragg
