qui-tam
Preserved but no longer current.
A solicitor. He who, i.e., "he who, as much for himself as for the King," seeks a conviction, the penalty for which goes half to the informer and half to the Crown. The term would, therefore, with greater propriety, be applied to a spy than to a solicitor.
Era: ca. 1874 (Victorian)
