Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid using 'garantiya' for weak promises; English 'guarantee' is stronger and more formal.
- Do not confuse with 'warranty'—they are often interchangeable, but 'warranty' is more specific to products.
- The verb 'to guarantee' requires a direct object or clause; it is not used intransitively like some uses of 'гарантировать'.
Common Mistakes
- Incorrect: *'I guarantee you.' (Missing what is guaranteed) Correct: 'I guarantee success.' or 'I guarantee you success.'
- Incorrect: *'It's a guarantee for one year.' (Less common) Correct: 'It comes with a one-year guarantee.' or 'It's guaranteed for one year.'
- Incorrect spelling: *'gaurantee', *'garrantee'.
