What does instantiate mean?
Instantiate means to make something real, concrete, or operational. In ordinary and legal writing, it can describe a situation that gives practical effect to an abstract rule, principle, or claim: a case may instantiate a broader theory of justice. In computing, it has a precise technical meaning: to create a concrete instance of a class, object, or other defined structure. The verb is useful when the contrast between a possibility or description and an actual, functioning example matters. It is more formal than simpler alternatives such as “create” or “put into practice,” but it can also convey the specific idea of turning an abstract model into a tangible realization. Related terms include the noun “instantiation,” meaning the process of creating an instance, and the adjective “instantiated,” describing something that has been made concrete.

Latin “instans,” the source of related English words such as “instant,” “instance,” and “instantaneous,” carried the idea of something being present or occurring at a particular time.
