An archaic feudal or legal term, possibly referring to a tax, right, or claim; historical meaning is uncertain and usage is extremely rare.
Possibly related to have with the suffix -age (which often indicates a right, duty, or payment), or a variant of havage, though historical documentation is minimal.
Haveage appears so rarely in medieval documents that scholars still don't agree on what it meant—it might have been a regional term that died out before anyone wrote down a clear definition!
