Origin

This character combines wood (the left component) with a sound hint on the right. Wood naturally decays and rots over time when exposed to moisture and age, so the wood radical directly expresses the core meaning. The right component serves as a phonetic guide to how the character should be pronounced rather than adding meaning. Together, the character depicts the concept of wood deteriorating—whether through literal rotting or, by extension, the secluded decline that comes with age.
