Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid direct translation with 'святыня' (shrine/relic) for secular contexts. For a private room, 'убежище' (refuge) or 'кабинет' (study) might be closer.
Common Mistakes
- Using it as a synonym for any 'room'. Confusing it with 'sanction'. Incorrect plural: 'sanctums' is correct, 'sancta' is rare and hyper-formal.
