捐出 is a verb meaning 'to donate' or 'to give up (something valuable) for a good cause.' It combines 捐 (juān), which means 'to donate' or 'to contribute,' and 出 (chū), which adds the sense of 'out' or 'forth' — together conveying the idea of actively handing something over to others, especially for charitable, medical, or public benefit. Unlike the more general 给 (gěi, 'to give'), 捐出 implies intentionality, selflessness, and often a formal or socially meaningful context.

This word is commonly used with concrete nouns like money, blood, organs, or property — for example, donating blood before surgery or giving away old books to a school. It carries a positive, respectful connotation and appears frequently in news reports, public service announcements, and health education materials. It is not used for casual or everyday giving (e.g., lending a pen), nor does it imply loss or coercion — the donor acts voluntarily and altruistically.
