  • Avoid direct calque 'перебронировать' (which implies re-booking). Use 'принять бронь сверх вместимости' or 'забронировать слишком много мест'.

Common Mistakes

  • Using 'overbooked' as an adjective for a person ('I am overbooked' is informal; 'my schedule is overbooked' is better). Confusing with 'overlook'.
