Examples of "Ad hoc"
Examples of the use of this famous Latin phrase can be found in schools and in the modern workplace.
An unexpected situation may have arisen that required attention, so an unplanned impromptu 'Ad hoc' meeting might be organised for this specific purpose.
A team of people might be required to attend such a meeting and therefore their appointment to a meeting, or perhaps a committee, would also be unplanned or 'Ad hoc'.
This phrase is relevant to any event that is organised purely for an unexpected and specific purpose, rather than planned carefully in advance.
