Expert writing Tips

Best practice

Always use the base form of a verb after the auxiliary verb "did". The correct phrasing is "did not fail".

Common error

Avoid using the past participle form ("failed") after "did not". The auxiliary verb "did" already indicates the past tense, so the main verb should be in its base form ("fail").
