Origin

This character combines a time marker (卯, which refers to the dawn hours in the traditional Chinese zodiac system) with a field (). The pairing suggests something fixed or anchored at a particular place or moment — the idea of halting motion or keeping something in place. Over time, the specific zodiac meaning faded, leaving only the sense of "detain" or "stop" that remains today. The visual structure of a marker sitting above a bounded space reinforces the notion of something being held or fastened in position.
