crime-fighting

The compound "crime-fighting" is a modern English formation that transparently combines two native concepts. The first element, "crime," has a long journey from Latin crīmen, which originally meant a judicial decision or charge, before specializing to mean the offense itself. The second element, "fighting," derives from the robust Old English verb feohtan, meaning to combat or struggle. When combined in the 20th century, the term creates a vivid, literal image of engaging in combat against criminal activity. This compounds the abstract notion of illegal acts with the active, physical metaphor of battle, reflecting a societal view of law enforcement as a proactive struggle.
