fin. The Yiddish word finnif is probably the ancestor of our slang for a five-dollar bill. Finnif meant a five-pound note in mid-19th-century England. Shortened to fin in England, it became American underworld slang by the 1920s. The Yid- dish word, in turn, derives from the German funf, or “five.” The fin of a fish comes from the Old English finn meaning the same. |
