The word "co-sponsor" combines the prefix "co-" (from Latin "com-," meaning "together") with "sponsor" (from Latin "sponsor," meaning "guarantor" or "supporter"). The prefix "co-" emphasizes collaboration, while "sponsor" retains its original sense of providing support or backing. The term emerged in the mid-20th century, reflecting modern organizational and legislative practices where joint sponsorship is common.
