Common Pitfalls

Translation Traps (for Russian speakers)

  • False friend: 'безопасность' (bezopasnost') is closer to 'safety'. 'Security' often translates as 'безопасность', but also 'охрана' (protection service), 'гарантия' (guarantee), or 'ценная бумага' (financial instrument).

Common Mistakes

  • Using 'security' as a countable noun for the abstract concept (e.g., 'I need a security' instead of 'I need security').
  • Confusing 'security' (state/measures) with 'safety' (condition of being safe from accidental harm).
  • Misspelling as 'securty'.

Frequently Asked Questions
