Vilho is a Finnish given name, functioning as a diminutive of Vilhelm, the Scandinavian and Finnish form of William. While originally a short form, Vilho has gained widespread use in Finland as an independent name for boys, reflecting a common Nordic pattern where diminutives evolve into standalone given names.EtymologyThe name traces its roots through the Germanic name Willehelm, composed of the elements willo meaning "will, desire" and helm meaning "helmet, protection," collectively interpreted as "will helmet." This name was popularized across Europe by the Normans and entered Finland through Swedish influence during the era of Swedish rule, where Vilhelm was adapted into Finnish as Vilho, alongside variants like Vili, Viljo, and Ville.Notable BearersSeveral notable Finnish individuals have borne the name Vilho.
