Idioms and Phrases with ad hoc

ad hoc

For the special purpose or end at hand; also, by extension, improvised or impromptu. The term, Latin for “to this,” is most often used for committees established for a specific purpose, as in The committee was formed ad hoc to address health insurance problems. The term is also used as an adjective (An ad hoc committee was formed), and has given rise to the noun adhocism for the tendency to use temporary, provisional, or improvised methods to deal with a particular problem.
