おやすみ
oyasumi
In Japanese, the way to say goodnight to your girlfriend is おやすみ (oyasumi).
This is a casual expression used to wish a romantic partner a good night's sleep.
Which one should you use?
While おやすみ is casual and suitable for a girlfriend, the form おやすみなさい is more formal and would sound slightly stiff in a close romantic relationship. There is also an even more casual, shortened form: おやす.
How do you pronounce it?
oyasumi
Did you know?
- If a boyfriend uses the formal おやすみなさい with his girlfriend without any irony, it can actually create a sense of 'distance' (kyori) that might make her feel he is being cold or overly polite.
- The word おやすみ originates from the verb やすむ, meaning 'to rest'. By adding the polite prefix お, you are essentially saying 'Please have a rest'.
- In many romantic Japanese-language songs, a character might avoid the standard おやすみ and instead use more poetic descriptions of the moon or the stars to imply a 'goodnight' to their lover.
