Betrayal is the act of breaking someone’s trust in a serious way, especially by helping an enemy or revealing secrets. It often causes deep emotional pain and a sense of being abandoned.
Formed from the verb “betray” with the noun-forming ending “-al.” “Betray” itself comes from Latin “trādere,” meaning “to hand over” or “to deliver.”
Betrayal hurts more than a normal mistake because it attacks the invisible contract of trust between people. That’s why stories in every culture have powerful betrayal scenes—our brains are wired to fear them.
