Did You Know?
In Latin, ad hoc literally means "for this." That historical meaning is clearly reflected in contemporary English uses of ad hoc—anything that is ad hoc 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 case at hand apart from other applications," as in "a commission created ad hoc." The adverb is older: it has been used in English since the mid-17th century, whereas the adjective did not become part of the language until about the mid-19th century.

"Possible art projects … include a new mural, a music festival or concert series and a sculpture made from a dead tree in Montezuma Park.
