Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with 'to search thoroughly' (обыскивать). The Russian 'трещать' (to crack, to chatter) is a false friend. The sense of 'defeat utterly' is stronger than просто победить (to beat).
Common Mistakes
- Using 'thrash' for a single, precise hit (use 'strike' or 'hit'). Confusing 'thrash' (violent beating) with 'trash' (discard, criticize). Incorrect preposition: 'thrash with an issue' instead of 'thrash out an issue'.
