Look: "Bom dia!" in Portuguese means "Good morning!"; "Buenos días!" or "Buen día" (this latter being less used) is Spanish, having the same meaning; now "Bos dias!" is in Galician and means the same.
"bon" mean "good" and partir mean "to leave"
a sweet
Bon appetit!
"Pas bon" = "Not good"
"Pas bon" = "Not good"
I don't think "dias" is a Latin word. "Dies" means "day", and "Deus" means God, but as far as I know "dias" doesn't mean anything.
"Cuatro dias" means four days in English.
Buenos dias Alberto mean "Good Morning Alberto"
c'est bon = that's good
"bon voyage" means "farewell"
'bon' means 'good'.
bon = good jour = day bon jour = good day
