In general usage, a thesaurus is a reference work that lists words grouped together according to similarity of meaning, in contrast to a dictionary, which provides definitions for words, and generally lists them in alphabetical order.The main purpose of such reference works is to help the user “to find the word, or words, by which [an] idea may be most fitly and aptly expressed” – to quote Peter Roget, architect of the best known thesaurus in the English language.
