What is the difference between Oyasumi and Oyasuminasai?


Why are these 2 words different? Google Translate says they mean the same
thing. When would each be used?




Both mean _good night_ , but the shorter one is less polite.

You must use おやすみなさい, the longer one, when you say good night to your guest,
teacher, boss, etc. To your family, whichever is fine. Kids are generally
taught to use おやすみなさい first, and then they start to use おやすみ somewhere in
their childhood.
