thesaurus originally, a dictionary or encyclopedia; after the publication of Roget's Thesaurus, the meaning narrowed to its current sense of a book that lists words in groups of synonyms and related concepts. Recorded in English from the late 16th century, the word comes via Latin from Greek thēsauros ‘storehouse, treasure’.
