Etymology

It is borrowed from Ancient Greek εὖ (eû, “well”), the Greek adverb used as an exclamation.[2][3][1][4]

Earliest recorded meaning

It is found first in Plautus, as a cry of approval or joy, “fine!”, “well done!”.[2][3][5]

Semantic evolution

It belongs to the language of comedy: Plautus and Terence use it often, sometimes ironically, and Plautus combines it with oaths in eu hercle and eu edepol.[2][3][5] Horace uses it once, in the Ars Poetica,[3][6] and Köbler also records it on inscriptions.[4]
