Old English þeah (þe) is well attested as a concessive conditional and concessive connective. Two occurrences in the Anglo-Saxon law-codes, however, not only fulfill all the logical criteria of a conditional marker but also clearly parallel the if-then strategy characteristics of pre-Conquest legislation. It is suggested that OE þeah (þe) represents a stage of polysemy in the process of semantic change from conditional to concessive conditional and concessive meaning.
