Word of the Day
postliminy
  • In Roman antiquity, the return of a person who had been banished, or taken prisoner by an enemy, to his old condition and former privileges.
  • In international law, that right by virtue of which persons and things taken by an enemy in war are restored to their former status when coming again under the power of the nation to which they belonged.
The word 'postliminy' comes from a Latin word meaning 'threshold'.
