Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid direct calque from 'разматывать' for abstract contexts; 'uncoil' is more physical. For mental relaxation, use 'unwind' or 'relax'. Do not confuse with 'uncouple' (расцепить).
Common Mistakes
- Using 'uncoil' for untangling knotted string (use 'untangle').
- Using 'uncoil' as a noun ('an uncoil' is incorrect).
- Confusing 'uncoil' (smooth unwinding) with 'unroll' (flat surface).
