If it's morning, say "Good day"...

In the Romance languages, morning runs until around noon, just like English. But you wouldn't know it from the greetings. People just say, "Good day." Here, then, the words for morning, but with a suggested greeting you already know. The words, by the way, come from the Latin mane - morning - and matutinus - of the morning.

French and Italian liked the adjective form; Spanish preferred the noun. Ready?

mane becomes Spanish mañana (ma-nya-na).

matutinus becomes Italian mattina (mat-teenah).

matutinus becomes French matin (mah-taihn - the second syllable has an "a" like cat but pronounced nasally).

But "Good morning" is Buenos días, Buongiorno, Bonjour in the order Sp./It./Fr.

Incidentally, the Spanish and Italian words are feminine (like "night"). The French is masculine (like "day"). But there is a feminine French form meaning "all morning long" - matinée. It used to be that watching the early show was a good way to fill up your morning. When they moved the early shows to the afternoon they kept the name.
