- Avoid direct calques like *'истечение'* for all contexts; for 'expiry date', use 'срок годности'. For contract expiry, 'окончание срока действия' is more accurate.
Common Mistakes
- Using 'expiry' as a verb (incorrect: 'The milk will expiry soon.' Correct: 'The milk will expire soon.').
- Confusing 'expiry' (the event) with 'expiration' (the event OR the act of breathing out).
