Expert writing Tips
Best practice
Always use the base form of the verb after the auxiliary verb "did". The correct form is "did not lead", not "did not led".
Common error
Avoid using the past participle form of the verb (led) after "did". "Did" already indicates past tense, so the base form (lead) is required.
