Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid confusing with 'лжец' (neutral term) and 'врун' (more colloquial, less severe). 'Liar' carries the weight of 'лжец'.
- Do not translate 'liar' as 'обманщик' in all contexts. 'Обманщик' can imply a broader 'cheater' or 'swindler', while 'liar' is specifically about verbal falsehoods.
Common Mistakes
- Incorrect: 'He is a liar person.' (Correct: 'He is a liar.' or 'He is a lying person.')
- Incorrect plural: 'liers' (Correct: 'liars').
