Origin

This character combines a heart radical on the left, which marks it as relating to emotions and inner feelings, with the character 感 on the right that serves as a sound hint for pronunciation. The heart radical signals that this is about an emotional state, while 感, which means "feeling" or "sensation," both hints at the sound "kan" and reinforces the emotional nature of the character. Together they form a character meaning regret or remorse—a painful feeling held in the heart.
