VAVASOR

A vavasor is a historical term used in Law Latin to refer to a vassal or tenant of a baron. They were individuals who held land under a baron and also had subtenants. The term can also be spelled as vavasour.

• John was a vavasor who held land under the baron and also had subtenants who paid him rent.
• The vavasor owed military service to the baron in exchange for the land he held.
