About This Root

From Latin ūtī (to use), past participle ūsus. Variants ut-, uti-, util-. One of the most common roots in everyday English: use, useful, useless, usage, usable. The utility branch (from ūtilis) adds utilitarian and utilize. Reusable shows how modern English keeps building on this ancient root. Abuse and misuse add negative prefixes to the same base.
