Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid direct translation with 'атрий' (extremely rare/archaic in modern Russian). For architecture, use 'атриум' (loanword) or 'внутренний двор/пространство'. For anatomy, use 'предсердие'.
Common Mistakes
- Confusing 'atrium' (upper heart chamber) with 'ventricle' (lower heart chamber). Using 'atrium' to refer to any large room instead of a specific central, often multi-storey, skylit space.
