Origin

This character combines a person (the left component) with dawn or daybreak (the right component). The idea is that a person at dawn represents a moment of clarity or truthfulness—just as dawn breaks through darkness to reveal what's real, the character came to mean "however" or "but," marking a point where truth or reality interrupts or contrasts with what was said before. Over time, the meaning shifted to express the logical turning point that "but" represents in speech.
