A '''thesaurus''' lists [[synonym]]s and [[antonym]]s of index words.  Peter Mark Roget published the first thesaurus, ''Thesaurus of English Words and Phrases'' in the 1850's, and current editions have become known simply as ''Roget's'' or ''Roget's Thesaurus'' <ref>http://www.beyondbooks.com/law81/1j.asp</ref>.  Most thesauruses (or thesauri) list index words alphabetically like a [[dictionary]], but Roget organized the words topically.

The word thesaurus comes from the greek θησαυρός, which means "treasury." Contrary to popular belief, the use of the -σαυρός suffix here is coincidental and unrelated to lizards.
