Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with "disability" (инвалидность). "Debility" is general weakness, not a specific condition. Avoid translating as "слабоумие" (which is dementia/mental deficiency). Closer to "слабость, немощь, дряхлость".
Common Mistakes
- Incorrect: 'He felt a debility in his arm.' (Use 'weakness' or 'numbness' for localized sensation). Correct: 'The fever left him in a state of debility.'
- Incorrect: 'mental debility' as a direct synonym for learning disability or intellectual impairment (it's too vague and outdated for this).
