Sense: verb/1

All four words describe moving a hand or tool across a surface, but they differ in pressure, purpose, and tool. 'Rub' is the most general — you can rub your eyes, rub a surface clean, or rub in lotion. 'Massage' is gentler and slower, done deliberately on the body to relax muscles or relieve pain, often with oil. 'Scour' involves much harder pressure with an abrasive material (a scouring pad, sandpaper) to remove tough dirt. 'Wipe' is the lightest — a quick pass with a cloth to remove dust or liquid, without much pressing. 'Polish' focuses on the outcome: rubbing with a special cloth or substance to make a surface smooth and shiny. Compare: you wipe a spill off the counter, rub the surface dry, scour a burnt pan with steel wool, and polish silver until it gleams. Each word picks a different part of the rubbing spectrum.

Etymology

GermanicMiddle EnglishEnglish

The word 'rub' comes from Middle English 'rubben', which may have come from Old English 'rubian' (to rub) or from Old French 'rubiner' (to bore or scrape). It is related to similar words in other Germanic languages, such as Danish 'rubbe' (to scrub) and Swedish 'rubba' (to move or shift). The noun meaning 'a difficulty or obstacle' (sense 3) comes from a famous line in Shakespeare's play Hamlet (around 1600): 'To sleep, perchance to dream — ay, there's the rub.'
