Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid direct translation with 'глупость' in all contexts. 'Foolishness' often implies a more blameworthy or significant error, whereas 'глупость' can be softer, even endearing. For a simple mistake, 'silly thing' might be closer. Do not confuse with 'stupidity' (тупость), which is stronger and implies lack of intelligence, not just poor judgement.
Common Mistakes
- Using 'foolness' (non-existent word). Correct: foolishness. | Incorrect preposition: 'foolishness about that plan'. Correct: 'foolishness of that plan'.
