留

Phono-semantic compound:

田 (밭 전, “field”) — semantic, indicating a place where one remains to cultivate or work.

卯 (토끼 묘, “rabbit, fourth earthly branch”) — phonetic, providing the sound 류 (liú).

The original sense is “to remain in a field,” implying settling down and staying to cultivate, which extended metaphorically to “stay,” “remain,” or “detain.”

The form 畄 was once proposed as a second-round simplified form in mainland China but later abolished.
