To call together; to convene or summon an assembly or gathering (archaic or formal).
From Latin convocare (to call together), from com- (with) and vocare (to call). The verb form preserves the direct Latin sense.
Convocate is the forgotten verb form that gave rise to 'convocation'—most modern English speakers would use 'convene' instead, but convocate is still technically correct and you'll find it in historical religious and academic texts.
