Expert writing Tips

Best practice

Always use the correct form "did not leave" instead of "did not left". The auxiliary verb "did" requires the base form of the main verb.

Common error

Avoid using the past tense form of the verb (left) after the auxiliary verb "did". The correct structure is "did + not + base form of verb" (e.g., did not leave).
