Treason entered English in the Middle English period and comes from the same root as tradition and traitor: Latin tradere, “to deliver” or “hand over,” formed from trans-, “across,” and dare, “to give.” Its underlying sense is the act of handing over.
Etymology
From Middle English tresoun, treison, from Anglo-Norman treson, from Old French traïson (“treason”), from trair, or from Latin trāditiō (“a giving up, handing over, surrender, delivery, tradition”), from trādō (“give up, hand over, deliver over, betray”, verb), from trāns- (“over, across”) + dō (“give”). Doublet of tradition.
