Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid direct translation of 'уменьшать' for all contexts; 'diminish' is for gradual reduction of abstract/non-physical things more than physical objects. For 'make physically smaller', 'reduce' or 'shrink' is often better.
- Do not confuse with 'минимизировать' (to minimise), which implies reducing to the smallest possible amount.
Common Mistakes
- Using 'diminish' with a person as a direct object to mean 'belittle' is correct but formal/dated (e.g., 'He diminished her achievements'). In modern speech, 'belittle' or 'downplay' is more common.
- Incorrect: 'The population was diminished by half.' (Better: 'reduced by half')
