- Do not confuse with 'нашествие' which can imply a horde or swarm; 'invasion' is more strategic and organised.
- The metaphorical use ('invasion of privacy') directly translates as 'вторжение в частную жизнь'.
- Avoid using 'invasion' for peaceful mass arrivals (use 'influx').
Common Mistakes
- Using 'invasion' for a natural, peaceful migration of people (Incorrect: 'The invasion of tourists every summer.' Correct: 'The influx of tourists...').
- Confusing 'invasion' (the act of entering) with 'occupation' (the act of staying and controlling).
