Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with 'дефектор' (nonexistent) or 'дефектный' (defective). The Russian equivalent is typically 'перебежчик' (often for military/political) or 'отступник' (more ideological/religious). 'Дезертир' is more specific to military desertion.
Common Mistakes
- Mispronunciation: /ˈdiːfɛktə/ (incorrect). Incorrect use for someone who simply resigns or retires without joining an opposition. Confusing spelling with 'detector'.
