不亦乐乎
- Literal
- is it not also a joy?
- Figurative
- Originally "isn't it a joy?"; today, after 得, it means "like crazy": 忙得不亦乐乎 is to be run off your feet, said half-jokingly.
Where does 不亦乐乎 come from?
These are the opening words of the Analects of Confucius: "To learn and practice in due time what one has learned, is that not also a pleasure? To have friends come from afar, is that not also a joy?" Outside that quotation, still a stock welcome for friends from afar, the phrase changed its job: today it follows 得 as a complement of degree and means "extremely, flat out," with a humorous ring that comes from the contrast with the solemn original. So 忙得不亦乐乎 is not enjoying your work but being swamped, while 玩得不亦乐乎 is having a great time.
