This article is about the Latin phrase. For other uses, see Ad hoc (disambiguation).

Ad hoc is a Latin phrase meaning "for this". In English, it generally signifies a solution designed for a specific problem or task, non-generalizable, and not intended to be able to be adapted to other purposes (compare with a priori).

Common examples are ad hoc organizations, committees, and commissions created at the national or international level for a specific task. In other fields, the term could refer, for example, to a military unit created under special circumstances, a tailor-made suit, a handcrafted network protocol (e.g. ad hoc network), a temporary banding together of geographically-linked franchise locations (of a given national brand) to issue advertising coupons, or a purpose-specific equation.

Ad hoc can also be an adjective describing the temporary, provisional, or improvised methods to deal with a particular problem, the tendency of which has given rise to the noun Adhocism.[1] It also could mean shifting contexts to create new meanings or inadequate planning. [2]


According to The Chicago Manual of Style, familiar Latin phrases that are listed in Merriam-Webster, such as "ad hoc", should not be italicized.[3][4]

In the military, ad hoc units are created during unpredictable situations, when the cooperation between different units is suddenly needed for fast action, or from remnants of previous units which have been overrun or otherwise decimated.
