Vavasor

n. [Also written varasour, varassor, varassour, valvasor, valvassor, and valvassour.] [O. Fr. varasseur, varassor, vasseur, Fr. vasvassor, valvassor, It. varvassore, barbassoro, L. Lat. vavassor, vavassorius, valvassor, vasvassor, probably contracted from vassus vassorum, vassal of the vassals. See VALET and VASSAL.] (Feudal Law.) The vassal or tenant of a baron; one who held under a baron, and who also had tenants under him; one in dignity next to a baron.

The term varasor first came into use in England after the Conquest, being another form of valvasor, which was employed in the feudal law of the continent. Burrill. “Vasorours subdivide again to vassals, exchanging land and cattle, human or otherwise, against fealty; and so the iron chain of a military hierarchy, forged of mutually interdependent links, is stretched over each little province.” Motley.
