- (music) "for two", indicating both musicians or sections play together
- → Norwegian Bokmål: a due
Borrowed from Italian a due (“for two”), first part from Italian a (“in, at, to”), in most cases from Latin ad (“to, towards, up to, at”), from Proto-Italic *ad (“toward, to, on, up to, for”), from Proto-Indo-European *h₂éd (“to, at”), in certain cases, from Latin a (“from, away from, out of”), from ab (“from, away from, out of, down from”), from Proto-Italic *ab, from Proto-Indo-European *h₂epó (“off, away”). Last part from Latin duae, feminine plural of duo (“two”), from Proto-Italic *duō (“two”), from Proto-Indo-European *dwóh₁ (“two”).
