Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with 'admit' only in the sense of 'confess a crime' ('признаваться'). 'Acknowledge' is broader.
- It is not a direct equivalent of 'подтверждать' in all contexts (use 'confirm' for factual verification).
- Be careful with 'to acknowledge someone' as 'to greet' – it's a specific use.
Common Mistakes
- Incorrect: 'I acknowledge to make a mistake.' Correct: 'I acknowledge making a mistake.' or 'I acknowledge that I made a mistake.'
- Overusing in informal contexts where 'admit' or 'say' is more natural.
- Confusing spelling: 'acknowledge' not 'acknowlege'.
