Did you know?

In Latin ad hoc literally means "for this," and in English it describes anything that can be thought of as existing "for this purpose only." For example, an ad hoc committee is generally authorized to look into a single matter of limited scope, not to pursue any issue of interest. Ad hoc can also be used as an adverb meaning "for the particular end or case at hand without consideration of wider application," as in "decisions were made ad hoc."
