IN THE MORNING: bonjour in the afternoon: bonjour / BON après-midi in the evening: bonsoir it's a easy as that NEVER: bon mattin when you are greeting s.o. Kind regards martine

good morning = bonjour (8h-12h am) ; good afternoon = bon/bonne après-midi, bonsoir (1pm-6pm) ; good evening = bonsoir (6pm- 12pm)

Si on se voit le matin - on dit : bon matin. Si on voit qn dans la journee - on lui dit - bonjour. Et si on rencontre qn le soir - on lui dit - bon soir . If you want to greet someone in the morning, you just say【 bonjour】. The only time you would use 【bon matin】is in the expression "de bon matin", which means "bright and early". 如果只是欢迎某人、和那人打声招呼，只需要说【bonjour】......另外，在法国，人们一般只说【bonjour】，而【Bon matin 】是错误的。
