Background / Comments
It came into English from Latin, but the word traces back to Greek; specifically from antonomazein (to call by a new name), which has as its base onoma (name). In sports, the second part of the definition is pretty common: “The Refrigerator” or “The Great One” are some of them. The first part would be more like calling someone a “Beau Brummell” or something along those lines.
