What is the Meaning of 樂於 (lè yú)?
The phrase 樂於 (lè yú) literally translates to “to be happy to” or “to take pleasure in” doing something. It conveys a positive attitude or willingness towards an action or task. 樂 (lè) means “joy” or “happiness,” while 於 (yú) functions as a preposition meaning “in,” “at,” or “towards.” When combined, 樂於 expresses the idea of feeling joyful or willing about an action.
In usage, 樂於 is typically followed by a verb to indicate the specific activity one is glad or willing to engage in. It highlights a proactive and positive emotional stance rather than mere obligation or neutrality.
Nuances of 樂於 Compared to Similar Expressions
- 喜歡 (xǐ huān) — simply “to like”; more neutral and general liking or preference.
- 願意 (yuàn yì) — “to be willing,” focusing on willingness but less on joy or pleasure.
- 樂於 (lè yú)

Thus, 樂於 often carries a stronger, more heartfelt enthusiasm than just “willing to.”
