Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with 'измена', which can mean both 'betrayal' and 'infidelity' (sexual). 'Betrayal' is broader. The Russian word 'предательство' is a more direct equivalent.
- Avoid using 'betrayal' for minor let-downs; it is for serious breaches of trust.
Common Mistakes
- Incorrect: 'His lie was a betrayal for me.' Correct: 'His lie was a betrayal of me' or '...was a betrayal of my trust.'
- Incorrect spelling: 'betrayel', 'betrail'.
- Overuse for minor disappointments.

FAQ
Frequently Asked Questions
'Betrayal' is broader and focuses on the broken trust within a relationship. 'Treachery' is more formal/literary and emphasizes deliberate deception and danger, often in political/military contexts.
Typically, no. 'Betrayal' implies a conscious or negligent act that breaks trust. For an unintentional revelation, words like 'inadvertent disclosure' or 'slip' are better. However, one can *feel* betrayed by an unintentional act.
Yes. It carries significant negative emotional and moral weight. It is not used for minor disappointments like a friend being late.
The direct adjective is 'betrayed' (the victim's state: 'a betrayed friend'). For describing the act itself, 'betraying' is used ('a betraying glance'). The adjective 'treacherous' is a close synonym.
