ohayō
Did you know?
- In many Japanese workplaces, colleagues will say おはよう to one another even if it is actually afternoon or evening. This is because the phrase functions as a greeting for the first time you encounter someone during a workday, rather than a reference to the sunrise.
- The phrase おはよう is actually a frozen piece of grammar from the past. While most modern Japanese adverbs end in -ku, this expression uses a rare -u ending that has survived since the Muromachi period.
- The word 'early' is hidden inside this greeting. Historically, you were not just saying 'good morning', but were literally complimenting the listener on being 'early' or 'prompt'.
Examples in context
- おはよう。ohayou.Good morning.
- おはよう、今日も暑いね。ohayou, kyou mo atsui ne.Good morning, it is hot today too.
