Origin

This character combines a roof radical at the top, which points toward the meaning of a dwelling or enclosed space, with the component for "uncle" at the bottom, which serves as a sound hint for how the character is pronounced. The idea of being alone or isolated in a quiet place — perhaps a solitary dwelling or a monk's quiet cell — led to the character developing meanings around loneliness, quietness, and the peaceful withdrawal associated with Buddhist monasticism. Over time, these senses of isolation and quiet maturity broadened to include the mellow, worn quality of things that have aged in seclusion.
