Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid direct translation with 'оператор' for all contexts. In IT, 'software operator' is incorrect; use 'user' or 'administrator.' In business, 'operator' is the company providing the service, not just an employee.
Common Mistakes
- Using 'operator' for a person who simply uses a computer app (use 'user'). Confusing 'operator' (company) with 'employee' in service contexts.
