Origin

This character is a simple picture of a mouth. The square shape represents the opening of the mouth, and the character has kept this straightforward visual form since ancient times. Because mouths are essential for eating, speaking, and breathing, this pictograph came to mean "mouth" in general, and it's now also used as a classifier in more complex characters to indicate meanings related to mouths, speech, or openings.
