Se Demander Conjugation in French: The Complete Guide & Charts

The reflexive verb se demander is one of the most frequently used verbs in everyday French. Translating directly into English as "to wonder" (literally "to ask oneself"), it belongs to the regular first conjugation group (-er verbs).

While its regular endings make it predictable, learners often stumble upon its reflexive pronouns and the subtle rules of past participle agreement. In this guide, our French linguistic experts break down every major tense with clear charts, real-life examples, and pro tips.

1. Present Tense (Présent de l'indicatif)

Use the present tense to express spontaneous inner thoughts, doubts, or questions occurring right now.

Example: Je me demande où sont mes clés. (I wonder where my keys are.)

2. Passé Composé: Auxiliary & Agreement Rules

Like all French reflexive verbs, se demander requires the auxiliary verb être in compound tenses.

💡 Expert Grammar Insight: The Past Participle Agreement

Notice that the past participle does not take an extra -e or -s in standard usage. Why? In French grammar, demander takes an indirect object for the person being asked (demander quelque chose à quelqu'un). Because the reflexive pronoun se stands for à soi-même (to oneself), se is an indirect object (COI).

Past participles with être in reflexive verbs only agree with a preceding direct object (COD). In 99% of spoken and written cases, se demander is followed by a subordinate clause (e.g., Elle s'est demandé pourquoi...), meaning there is no preceding COD. Therefore, demandé remains invariable.

Correct: Elle s'est demandé si elle devait venir. (NOT demandée)

3. Imperfect (Imparfait)

The imperfect describes continuous, habitual, or background wondering in the past.

Example: Nous nous demandions si tu allais appeler. (We were wondering if you were going to call.)

4. Simple Future (Futur Simple)

Example: Plus tard, tu te demanderas pourquoi tu as hésité. (Later on, you will wonder why you hesitated.)

5. Conditional (Conditionnel Présent)

Use the conditional for hypothetical wondering or polite internal queries.

Example: Je me demanderais deux fois avant d'accepter. (I would wonder twice before accepting.)

6. Present Subjunctive (Subjonctif Présent)

Triggered by expressions of necessity, emotion, or uncertainty (il faut que, bien que).

Example: Il est compréhensible que vous vous demandiez cela. (It is understandable that you wonder about that.)

7. Imperative Mood (Impératif)

Used when prompting someone to self-reflect or ask themselves a question:

• Demande-toi (Ask yourself – singular/informal)
• Demandons-nous (Let's ask ourselves)
• Demandez-vous (Ask yourself/yourselves – plural/formal)

Example: Demande-toi ce qui compte vraiment pour toi. (Ask yourself what really matters to you.)
