good morning = sa wadee thon chao
good afternoon = sa wadee krab/kha
Note:
actuallly don't really say "good afternoo" we will simply say, sa wadee ( which is can use for 24 hours)
morning = thon chao , chao
noon= thon tiang, tiang
afternoon= thon bai, bai
everning= thon yen, yen.
so, if you put them after" sawadee"........ is okay okay too.
good afternoon= sa wad dee thon bai krab/kha.
