Sabonner
Sabonner is a French verb in the infinitive form. It designates the act of applying soap or lather to someone or something, i.e., to wash with soap. The term is rare in contemporary French and is generally considered archaic or regional; in standard modern usage the verb savonner is used for the same sense.
Origin and scope: Sabonner derives from savon, soap, with a suffix pattern related to other -onner verbs.
Important distinction: Sabonner should not be confused with s'abonner (to subscribe) or abonner (to subscribe someone).
