Expert writing Tips
Best practice
Always use the correct past participle form of verbs. "Reply" is an action, and its correct past form is either "replied" as a verb or "reply" after a modal verb like "could not".
Common error
Avoid using the incorrect past participle form of "reply." Remember that after modal verbs like "could", "should", or "would", use the base form of the verb (e.g., "could not reply"), not the past participle (e.g., avoid "could not replied").
