A standing ovation is a form of applause where members of a seated audience stand up while applauding after extraordinary performances of particularly high acclaim. In Ancient Rome returning military commanders (such as Marcus Licinius Crassus after his defeat of Spartacus) whose victories did not quite meet the requirements of a triumph but which were still praiseworthy were celebrated with an ovation instead, from the Latin ovo, "I rejoice". The word's use in English to refer to sustained applause dates from at least 1831.
