Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid literal translation as 'открытый дом', which is not idiomatic for the event meaning. For a property viewing, use 'день открытых дверей' (although this also means open day) or 'показ недвижимости'. For a school event, 'день открытых дверей' is correct.
Common Mistakes
- Using 'open home' (common in NZ/AU, but not standard in UK/US). Confusing it with 'open bar' (free drinks) or 'open plan' (architecture). Incorrect preposition: 'open house of the school' instead of 'open house at the school'.
