捐

A phono-semantic compound composed of:

手 — semantic component meaning “hand; action”; 肙 — phonetic component indicating the sound (연 / juān). The original sense is to remove or give away something by hand, leading to meanings like discarding or offering.
Semantic development: - to discard or throw away; - to give up or relinquish; - to donate or contribute. The shift from “to discard” → “to donate” reflects the idea of giving something away voluntarily.

捐 is not frequently used in modern Korean vocabulary.

In modern Chinese, 捐 is strongly associated with charity, donations, and social contributions.
