CON'GE, n.¹ [con'jee; Fr. congé, leave, permission, discharge, contracted from conged; verb, congedier, to dismiss; It. congedo, leave, permission; congedare, to give lease; Arm. congea. The verb is a compound of con and ged; W. gadaw, to quit, to leave, to permit; gad, leave. Gadaw, is the Celtic form of the L. cedo. Conged is therefore concedo.]

1. Leave; farewell; parting ceremony. – Spenser.
2. The act of respect performed at the parting of friends. Hence, the customary act of civility, on other occasions; a bow or a courtesy. The captain salutes you with conge profound. – Swift.
