l'annulaire

fourth finger, ring finger

oliverbeer's mnemonic about annulling a marriage might be the easiest way to remember it, but actually, this comes from a word meaning "ring" (Latin "anulus"), just like the English name for this finger. There are some English words that come from the same root, though none of them are terribly common: for example, "annular" means "having to do with rings". by TL-qrs
