The Latin phrase \emph{ad hoc} translates as ``toward this'', and is used in mathematics to describe anything that has been made up specifically for one particular purpose.

\subsubsection*{Examples}
\begin{enumerate}
\item an ad hoc definition is a temporary definition that might
be useful for the discussion at hand. For instance, let a \emph{nice set} 
be a closed set with smooth boundary. 
\item If a proof makes use of an ad hoc construction,  the proof
(typically) does not make use of a general theory for the problem. 
\end{enumerate}
