Common Pitfalls
Translation Traps (for Russian speakers)
- Не путать с 'приманка' (bait) в чисто рыболовном смысле. 'Decoy' всегда подразумевает стратегический обман, а не просто наживку. Также не является прямым эквивалентом 'ловушка' (trap).
Common Mistakes
- Using 'decoy' as a synonym for any 'trap' (a decoy is part of a trap, not the trap itself).
- Misspelling as 'decoi' or 'deccoy'.
- Incorrect verb pattern: 'They decoyed him to go' instead of 'They decoyed him into going'.
