betray: betray: [13] Betray is an English formation based on the Old French verb traïr ‘betray’, which came from Latin tradere ‘hand over, deliver up’ (originally a compound formed from trans- ‘across’ and dāre ‘give’). The noun formed from tradere was trāditiō, from which English gets, directly, tradition, and indirectly, via Old French and Anglo-Norman, the appropriate treason.
