Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with 'изолировать' in the sense of 'to isolate a patient or prisoner' which is more about quarantine/separation. 'Insulate' focuses on protective separation, often with a material. Use 'утеплять', 'изолировать (от тепла/холода/звука)'.
Common Mistakes
- Confusing 'insulate' (protect with barrier) with 'isolate' (set apart). Incorrect: 'The doctor insulated the contagious patient.' Correct: 'isolated'.
- Incorrect preposition: 'insulate of' instead of 'insulate from/against'.
