I’ve long wondered about the word for today in various languages. Even within the Romance group, they seem so different: hoy, oggi, and aujourd’hui in Spanish, Italian, and French respectively. IIRC hodie is the Latin word, and it doesn’t take a huge leap of imagination to suppose that hoy comes from that word. But what about Oggi and especially aujourd’hui?
And as an aside, did the German word heute (today) also come into the language from Latin, via early Roman-German contact?
