Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid direct cognate 'импостор' – it doesn't exist. Correct translations are 'самозванец' (pretender to a position) or 'мошенник' (swindler) depending on context. For 'impostor syndrome', use 'синдром самозванца'.
Common Mistakes
- Misspelling as 'imposter' (acceptable but less standard). Confusing 'impostor' (person) with 'impost' (tax). Using it for inanimate objects incorrectly (e.g., 'the fake painting was an impostor').
