Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with 'нарушитель' in all contexts; 'нарушитель' is broader (e.g., нарушитель правил = rule-breaker). 'Intruder' is specifically about entering/being present. 'Вор' (thief) is not always correct unless theft occurs. Closest is 'злоумышленник, проникший внутрь' or 'незваный гость'.
Common Mistakes
- Using 'invader' interchangeably (invader implies larger scale/military). Confusing 'intruder' (person) with 'intrusion' (act). Incorrect preposition: 'intruder at the house' (less common) vs. 'intruder in the house'.
