requisit

Requisit is a scarcely used English form that is generally considered an archaic or nonstandard variant of requisite. In modern English, the standard term for something needed or required is requisite, used both as a noun (a requisite) and as an adjective (requisite conditions). The spelling requisit is seen only in historical texts or in regional or idiosyncratic spellings, and is not recommended for contemporary writing.

Etymology and related forms: Requisit derives from Latin requisitus, meaning “sought or required,” passing into English through older forms such as requisite. Related words include requisition, which has a different sense and usage. Requisition refers to a formal demand or request for goods, services, or personnel, or the act of making such a demand.

Usage guidance: Do not use requisit in place of requisite in modern prose. If you mean a thing that is necessary, prefer requisite (singular) or requisites/prerequisites for the plural. If you intend the sense of a formal demand, use requisition (not requisit). The word requisit is typically confined to historical texts or discussions of spelling variants and is not a standard term in current dictionaries.
