Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid direct translation with 'пятно' for every context; 'blotch' is specifically irregular and ugly. For a simple 'spot', use 'spot' or 'dot'. For a beautiful patch of colour, use 'patch' or 'splash'.
Common Mistakes
- Confusing 'blotch' (irregular) with 'blot' (often from liquid) or 'blob' (shapeless drop). Using it for small, neat spots. Incorrect adjective form: 'blotchful' (non-existent), correct is 'blotchy'.
