Middle English: from Old French traitour, from Latin traditor, from tradere 'hand over'.

  • tradition from Late Middle English:

    A tradition is something passed on and comes from Latin from tradere ‘deliver’ formed from trans- ‘across’ and dare ‘give’. The abbreviation trad dates from the 1950s, usually in the context of jazz. Traitor (Middle English), someone who hands over things to the enemy, and treason (Middle English) the act of handing over, are from the same root.
