Common Pitfalls
Translation Traps (for Russian speakers)
- Не переводить как "перекладывать" (to shift/transfer).
- Не путать с "overlap" (перекрываться, частично совпадать). "Overlay" — именно наложение поверх, а не рядом.
- В IT контексте — это именно "оверлей", слой, а не "наложение" в смысле конфликта.
Common Mistakes
- Confusing 'overlay' (present) with 'overlaid' (past/past participle). (Incorrect: 'She overlay the image.' Correct: 'She overlaid the image.')
- Using 'overlay' as a noun when the verb is needed, and vice-versa.
- Misspelling as 'overly' (which means 'excessively').
