Questions & Answers about J’ai perdu mon portefeuille.

Why is it J’ai and not Je ai?

Because of elision. In French, je becomes j’ before a word that starts with a vowel sound or mute h. ai (from avoir) starts with a vowel sound, so je ai contracts to j’ai.

What tense is ai perdu, and how does it compare to English?

It’s the passé composé: present of avoir + past participle (perdu). It refers to a completed past event. In English it often corresponds to both “I lost” and “I have lost,” depending on context. For background or habitual past, you’d use the imparfait: je perdais.

Why use avoir and not être as the auxiliary?

Most verbs, especially those that take a direct object, use avoir in the passé composé. Perdre is transitive (you lose something), so it uses avoir. Être is mainly for intransitive movement verbs (aller, venir, etc.) and all reflexive verbs. Related note: se perdre means “to get lost”: Je me suis perdu(e).

Does the past participle perdu agree with mon portefeuille?

Not here. With avoir, the past participle agrees only if a direct object comes before it. In J’ai perdu mon portefeuille, the object comes after, so no agreement. But:

• Je l’ai perdu (wallet, masculine singular) → perdu
• Je l’ai perdue (key, feminine singular) → perdue
• Je les ai perdus/perdues (masc./fem. plural) → agreement with what les refers to

Can I replace mon portefeuille with a pronoun? Where does it go?

Yes. Use a direct object pronoun before the auxiliary:

• Je l’ai perdu. = I lost it. (masculine singular)
• Je l’ai perdue. = I lost it. (feminine singular) Place the pronoun before ai; time adverbs go after the participle: Je l’ai perdu hier.

How do I make it negative?

Wrap the auxiliary with ne...pas:

• Je n’ai pas perdu mon portefeuille. Notes:
• ne becomes n’ before a vowel sound.
• Other negatives work the same way: Je n’ai jamais perdu mon portefeuille.

How do I turn it into a question?

Three common ways:

• Rising intonation: J’ai perdu mon portefeuille ?
• With est-ce que: Est-ce que j’ai perdu mon portefeuille ?
• Inversion (more formal): Ai-je perdu mon portefeuille ?

Why is it mon and not ma? What gender is portefeuille?

Portefeuille is masculine, so use mon: mon portefeuille. It’s un portefeuille / le portefeuille. Reminder: for feminine nouns that begin with a vowel or mute h, you also use mon for euphony (e.g., mon amie), but that doesn’t apply here.

Are there other common words for “wallet,” and do they mean the same thing?

• Un portefeuille: a wallet for bills/cards; also “investment portfolio” in finance.
• Un porte-monnaie / portemonnaie: usually a coin purse; in some regions (e.g., Switzerland), used for any wallet. If you’re unsure, portefeuille is a safe choice in France and Canada.

What are the pronunciation tips for the whole sentence?

• IPA: [ʒe pɛʁdy mɔʁtəfœj]
• Approximation: zhay pair-dy por-tuh-foy Key sounds:
• J’ai: [ʒe] (zh sound + ay).
• French r [ʁ] in perdu and portefeuille is uvular (back of the throat).

Can I say Je perds mon portefeuille instead?

Could I use a different determiner than mon? What’s the difference between mon, le, and un here?

• Mon portefeuille: my wallet (possession).

What’s the difference between perdre and verbs like manquer, tomber, or égarer?

• égarer: to misplace (softer, temporary): J’ai égaré mon portefeuille.
• tomber / faire tomber / laisser tomber: to drop: J’ai fait tomber mon portefeuille.
