(Apánagium, Apánamentum, and probably derived from panis, or panaggio, provision), lands or feudal superiorities assigned to the younger princes of a reigning family. The apanage descended to the lawful heirs-male; and in their default it reverted to the crown. It was customary for the sons of princes to derive their surnames from the apanage.—See Pasquier's *Recherches*, l. 2, c. 18; l. 8, c. 20. Henault's *Hist. de France*, anno 1283.
