Translation Traps (for Russian speakers)
- Do not confuse with 'предатель' which is a direct equivalent. Beware of false friend 'тракторист' (tractor driver). The Russian emotional weight is similar, but the English term may be used more broadly beyond political contexts.
Common Mistakes
- Misspelling as 'trader' or 'traitour' (archaic). Confusing 'traitor' (person) with 'treason' (the act). Incorrect preposition: 'traitor of' is less common than 'traitor to'.
