What does betrayed mean?
Betrayed is the past tense and past participle of the verb betray, meaning to have been disloyal or unfaithful to a person, cause, or country — most commonly by breaking trust, revealing secrets, or abandoning someone who relied on you. It can also describe the unintentional exposure of feelings or information, as when a trembling voice betrays nervousness. The word carries powerful emotional weight in everyday use: to say 'I felt betrayed' implies deep personal hurt from someone expected to be loyal. Its derivatives include betrayal (the noun) and betrayer (the person responsible). Betrayed ultimately derives from the Latin tradere, meaning to hand over or deliver up, the same root that gives us traitor, treason, and tradition. It appears frequently in discussions of friendship, politics, romance, and espionage, making it one of the more evocative words in English for describing broken faith and misplaced confidence.

Etymology of betrayed
Betrayed comes from the verb betray, which entered English in Middle English via Old French trair, itself from the Latin tradere, meaning to hand over or deliver up. This Latin root also produced traitor, treason, and tradition, all sharing the core idea of handing something across or passing it on. The word has carried its sense of treacherous disloyalty since its early adoption into English, reflecting the gravity of handing over a person or secret to an adversary.
