Bonjour Cheryl ! Let's take this negative statement in Le Passé Composé: "Tu n'as pas mangé aujourd'hui." (You haven't eaten today.) In an inverted question, it will become: "N'as-tu pas mangé aujourd'hui ?" Also have a look at our lesson on inverted questions in Le Passé Composé: https://progress.lawlessfrench.com/revision/grammar/how-to-form-inverted-questions-in-le-passe-compose-conversational-past I hope that's helpful! À bientôt !
