Passé Composé conjugation of mourir

Every form in the table below comes from VerbFlow’s verified conjugation tables for mourir. The passé composé is a compound tense: être in the present + the past participle mort. The participle never changes in the table below — the tables give the masculine singular form, and agreement is explained in the formation section.

Present perfect (passé composé) — mourir

Person Form
je suis mort
tu es mort
il/elle est mort
nous sommes mort
vous êtes mort
ils/elles sont mort

The gerund of mourir is en mourant and the past participle is mort. You need the participle for the perfect tenses and the gerund for constructions with en.

How the passé composé of mourir is formed

Take the present tense of the auxiliary être and add the past participle mort: je → suis mort, tu → es mort, il/elle → est mort, nous → sommes mort, vous → êtes mort, ils/elles → sont mort. So mourir gives suis mort, es mort, est mort, sommes mort, êtes mort, sont mort. Because the auxiliary is être, the past participle agrees with the subject in gender and number: a feminine subject adds -e and a plural subject adds -s. The tables on this page give the masculine singular form mort, as in suis mort; in real sentences, adjust the ending to match the subject. A note on the participle: mort is the only past participle for mourir in the verified tables. Do not invent a second participle, and do not borrow the participle of a similar verb.

When to use the passé composé of mourir

1. A finished event in the past

Common mistakes with mourir in the passé composé

Mistake 1: Using the wrong auxiliary

Wrong: “J’ai mort de rire.”

Right: “Je suis mort de rire.”

With mourir the passé composé takes être, not avoir. The correct form is suis mort.

Mistake 2: Using the present for a finished past event

Wrong: “Je meurs de rire hier.”

Right: “Je suis mort de rire hier.”

Yesterday’s finished event needs the passé composé (suis mort), not the present.

Mistake 3: Using the imperfect for a single finished event

Wrong: “Je mourais de rire hier.” (for one finished event)

Right: “Je suis mort de rire hier.”

The imperfect describes background and habit. One finished event yesterday takes the passé composé.

Mistake 4: Forgetting participle agreement with être

Wrong: “Elle est mort.” (said of a woman)

Right: “Elle est morte.” — with être the participle agrees with the subject; the tables give the masculine singular mort.

With être the past participle agrees in gender and number with the subject.
