Etymology

The word "wiper" derives from the verb "wipe" (Old English wīpian, meaning "to rub lightly") combined with the agentive suffix "-er," which indicates a person or tool performing an action. The term originally referred to a person who wipes, but by the 19th century, it evolved to describe mechanical devices (e.g., windshield wipers) that perform the wiping action automatically. The logic is straightforward: "wipe" + "-er" = "something that wipes."
