Origin

This character combines a roof radical at the top, suggesting an indoor gathering place, with a sound component below that hints at the pronunciation "en." The roof component evokes the idea of people gathering together under shelter, which naturally connects to the meaning of a banquet or feast—a social gathering held indoors. Over time, the character came to represent the festive occasion itself rather than just the physical space, giving it the full meaning of a celebratory party or banquet.
