Word origin
16th century, borrowed from Latin thēsaurus, from Ancient Greek θησαυρός (thēsaurós, “storehouse, treasure”); its current English usage/meaning was established soon after the publication of Peter Roget's Thesaurus of English Words and Phrases in 1852. Doublet of treasure.
Used in a sentence
“"Roget" is the leading brand name for a print English thesaurus that lists words under general concepts rather than just close synonyms.”
“As reference books go, the thesaurus has had a somewhat checkered history, in fact, and has probably occasioned as much bad writing as good.”
