Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid translating the revenge sense as 'платить назад' (literal, incorrect). Use 'отомстить' or 'расплатиться'. For the financial sense, 'вернуть деньги' or 'погасить долг' are appropriate.
Common Mistakes
- Incorrect word order: 'I will pay to you back' (correct: 'I will pay you back').
- Using 'pay back' for returning a physical object (use 'give back').
- Confusing 'pay back' with 'pay off' (the latter implies final settlement).
