Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with 'упрямство' (stubbornness). Obtuseness is about dull comprehension, not refusal. The closer concept is 'тупость' or 'недогадливость'.
- Avoid using 'тупость' in formal contexts where 'obtuseness' would be appropriate; 'тупость' is coarser.
Common Mistakes
- Confusing it with 'obscurity' (which is about being unclear) or 'obstinacy' (stubbornness).
- Misspelling as 'obtusness' (missing the 'e').
- Using it in casual conversation where it sounds unnatural.
