Etymology
The word "rototiller" is a 20th-century American English compound, trademarked by the Rototiller Company in 1932 before becoming a generic term. It is formed from the colloquial clipping "roto," derived from "rotate" (itself from Latin rota, meaning "wheel"), combined with the verb "till," from Old English tilian, meaning "to cultivate land." The final "-er" agent suffix creates a noun for the machine itself. The term's logic is transparently descriptive: it names a machine (-er) that performs cultivation (till) via a rotating mechanism (roto), directly linking its functional components to its modern identity as a soil-turning device.
