- Avoid translating Russian 'активность' directly as 'activeness' – 'activity' is the standard noun. Do not confuse with 'event' (мероприятие) – 'activity' is broader.
Common Mistakes
- Using 'activity' as a countable noun without an article when specific (e.g., 'We did activity' instead of 'We did an activity'). Overusing plural for uncountable concepts (e.g., 'There was a lot of activities' instead of '...a lot of activity').
