Translation Traps (for Russian speakers)
- Avoid direct translation from 'стимул' in all contexts. 'Stimulus' is more clinical/specific. For general 'motivation' or 'incentive', use those words instead.
Common Mistakes
- Using 'stimulant' interchangeably ('stimulant' is usually a drug). Confusing plural ('stimuluses' is incorrect, use 'stimuli'). Overusing in casual speech where 'reason', 'push', or 'motivation' is more natural.
