Today is Thesaurus Day.
A thesaurus is a “a storehouse, repository, or treasury” (see Dictionary.com) or more specifically a dictionary of synonyms and antonyms. For people like us, it’s word porn. There is, of course, an online thesaurus at Thesaurus.com that includes synonyms for “thesaurus” like “lexicon” and “onomasticon” and “dictionary of words,” all of which lead to other terms . . . it’s the TV Tropes of words.
Happy (Jubilant) Thesaurus (Onomasticon) Day (Diurnal Course)!
