Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid direct translation like 'безопасный депозитный ящик'. The standard Russian equivalent is 'банковская ячейка' or 'сейфовая ячейка'.
- Do not confuse with 'сейф' (a standalone safe). A safe-deposit box is specifically inside a bank vault.
Common Mistakes
- Misspelling as 'safety deposit box'.
- Using it as a verb, e.g., 'I will safe-deposit-box my jewels.' (Incorrect).
- Omitting the hyphen in formal writing (though acceptable in some styles).
