Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid direct translation with 'интеллект', which is broader and can mean 'IQ' or general intelligence. English 'intellect' is more specifically about rational, analytical capacity.
- Do not confuse with 'intellectual' (adjective/noun). 'Intellect' is the faculty; an 'intellectual' is a person.
Common Mistakes
- Using 'intellect' as a synonym for 'intelligence' in casual contexts (too formal).
- Incorrect pluralisation when referring to the faculty (e.g., 'He has strong intellects' -> 'He has a strong intellect').
