Cowcatcher → The word is formed from "cow" (from Old English "cu", meaning the domesticated animal) and "catcher" (from the verb "catch", meaning to seize or capture). A cowcatcher is a device on the front of a train designed to catch and clear obstacles, particularly cattle, from the tracks.
Think of a device that 'catches' ('catcher') cows ('cow') to keep trains safe from obstacles.
