rubbing

The word 'rubbing' is a straightforward English formation. Its core, the verb 'rub', entered Middle English from a Germanic source, carrying the concrete sense of moving an object against another with pressure. The addition of the Old English noun-forming suffix '-ing' creates an action noun, literally "the act of rubbing." This process directly yields the primary modern meaning. A specialized artistic and archaeological sense later emerged, where the action of rubbing a pencil over paper laid on a textured surface produces a copy or impression of that surface, giving us the second definition.

Structure: rub (to apply friction) + ing (noun suffix) 'rub' is a verb of uncertain origin, likely from Low German or a Scandinavian source (e.g., Danish 'rubbe'), meaning to scrape or apply friction. '-ing' is a suffix from Old English '-ung', '-ing', used to form nouns of action or result.
