Expert writing Tips

Best practice

Always use the base form of the verb after "did not". The correct form is "did not confirm", "did not deny", etc.

Common error

Avoid using the past participle form (e.g., "confirmed") after the auxiliary verb "did". "Did" already indicates past tense; therefore, the base form of the verb should follow. Instead of saying "did not confirmed", you should say "did not confirm".

Linguistic Context

The primary grammatical function is that of a negated past tense verb phrase. Although Ludwig AI flagged it as incorrect, the phrase attempts to express the action of not affirming or validating something in the past.

Are there other ways to express that something wasn't confirmed?

Yes, you can use alternatives like "failed to confirm", "could not confirm", or "did not verify" depending on the nuance you want to convey.

What's the difference between "did not confirm" and "denied"?
