Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid direct calque 'секретный' for all adjective uses; 'secret meeting' is fine, but 'secret admirer' is 'тайный поклонник', not 'секретный'.
- The noun 'секрет' can also mean 'secret ingredient' or 'gland secretion' in Russian – ensure context is clear.
- Do not overuse 'secret' for 'mystery' (тайна). A secret is knowingly concealed; a mystery may be unexplained but not necessarily hidden.
Common Mistakes
- *'He secreted the documents' (correct as verb 'to hide', but advanced) vs. '*He did it in secret way' (incorrect: 'in a secret way' or 'secretly').
- Confusing 'secret' (adj/noun) with 'discrete' (adj, meaning separate).
