捐献 is a formal verb meaning 'to donate'—especially in contexts involving life-saving or socially significant contributions, such as blood, organs, bone marrow, or money for public welfare. The character 捐 (juān) originally meant 'to contribute' or 'to give up voluntarily', while 献 (xiàn) means 'to present respectfully' or 'to offer'. Together, they emphasize both the voluntary nature and the respectful, often selfless intent behind the act.

This word is rarely used for everyday giving (e.g., handing a friend a book); instead, it appears in official announcements, medical settings, charity campaigns, and news reports. It carries a tone of solemnity and civic responsibility. You’ll commonly see it paired with nouns like 血 (blood), 器官 (organs), 骨髓 (bone marrow), or 善款 (donation funds). Unlike the more general 赠送 or 给, 捐献 implies altruism and institutional or social recognition.
