Expert writing Tips

Best practice

Always use the base form of the verb after the auxiliary verb "did". For example, use "did not fix" instead of "did not fixed".

Common error

Avoid using the past participle form of the verb (e.g., "fixed", "resolved") after "did". The correct structure is "did + not + base form of the verb" (e.g., "did not fix", "did not resolve").
