An archaic legal term meaning to establish the boundaries or limits of land or property; to determine or settle.
From Medieval Latin 'atterminare,' combining 'ad-' (to) and 'terminare' (to limit/determine from 'terminus'). Used in Middle English legal documents.
Medieval lawyers used 'attermine' when they literally walked property boundaries to mark where one person's land ended and another's began—the verb's purpose was making things definite.
