chúc ngủ ngon is the usual way to wish someone good night. To be polite, Vietnamese speakers put a kinship term or pronoun for the person inside the phrase rather than saying it bare.
What does it mean word for word?
chúc means to wish, ngủ means sleep and ngon means good, so the phrase literally means wish sleep good.
Which one should you use?
ngủ ngon is a shorter, more direct way to say sleep well. Adding nhé to the end, as in ngủ ngon nhé, makes it softer and more affectionate.
How does it change in a sentence?
Place the word for the person between chúc and ngủ ngon, for example a word for mom, dad or child.
What mistakes should you avoid?
Do not just say chúc ngủ ngon to a person on its own. Include the pronoun or kinship term that fits them.
