- Avoid directly translating as 'экспертиза' (which primarily means 'examination' or 'forensic analysis' in Russian). Better equivalents: 'квалификация', 'опыт', 'знания', 'компетенция'.
Common Mistakes
- Using it as a countable noun without a modifier (*'He has an expertise.'), though 'an expertise in...' is acceptable. Confusing it with 'experience' (expertise implies a higher, specialized level).
