- The adjective "deformed" is a direct translation of "деформированный" but is much stronger and more pejorative when applied to people.
Common Mistakes
- Using 'deformity' to describe a temporary or minor injury (use 'injury', 'sprain').
- Confusing 'deformity' (noun) with 'deformed' (adjective).
- Using in a casual, potentially offensive way about a person's appearance.
