Etymology

Origin of scrub¹

First recorded in 1300–50; of uncertain origin; Middle English verb scrobben, shrubben, borrowed from or related to Middle Dutch, Middle Low German schrobben “to scrub, scrape”

Origin of scrub²

First recorded in 1350–1400; Middle English shrub(be), shrob(be), Old English scrybb; see shrub ¹

Explanation

When you scrub something, you wash it forcefully. You might scrub your dirty bathtub with a brush and some bleach, for example. When you scrub your floor, you use elbow grease — in other words, you work hard to get the floor clean. You might need to scrub your fingernails after a morning working on your car's engine, rubbing with a nail brush to get the grease off. Word experts think that scrub comes from the Middle Low German word schrubben, which also means "to scrub."
