Origin

This character combines the idea of the mouth (口) with a shell or treasure (貝). In ancient times, shells were precious and valuable, and the combination suggests something precious that comes from the mouth — a song or beautiful vocal expression. The shell component likely evokes the idea of something refined and treasured, while the mouth clearly indicates sound and speech. Together they form a character representing the special kind of sound that is a song, something vocally beautiful and worth treasuring.
