Mourir is "to die," and it earns its place among the most irregular verbs in French. The present tense alone uses two stems: stressed meur- (je meurs, il meurt) and unstressed mour- (nous mourons, vous mourez) — a pattern called boot conjugation because the stressed forms (the four corners and the ils form) outline a boot shape on the standard paradigm grid. The futur and conditionnel add a third stem, meurr- with double-r, paralleling courir. The past participle is mort — and it agrees with the subject when mourir takes its auxiliary être: il est mort, elle est morte, ils sont morts, elles sont mortes.
This page covers every paradigm, the all-important auxiliary (être), the participle's agreement (which produces audibly distinct feminine forms), and the dense set of figurative uses — mourir de rire, mourir de faim, mourir d'envie, mourir d'ennui — that make mourir one of the most expressive verbs in colloquial French.
The conjugation pattern
The defining feature is the three-stem alternation:
- Stem 1: meur- — used in stressed positions (singular present, 3pl present, singular subjunctive, 3pl subjunctive, meurs imperative)
- Stem 2: mour- — used in unstressed positions (1pl/2pl present, all imparfait, infinitive, participles, passé simple)
- Stem 3: mourr- (double r, with o) — used in the futur and conditionnel
This three-way split is why mourir feels so unpredictable. Once you internalize "stressed forms have meur-, unstressed have mour-, futur/conditionnel have double-r mourr-," the paradigms snap into place.
Présent de l'indicatif — the boot pattern
| Person | Form | Stem | Pronunciation |
|---|---|---|---|
| je | meurs | meur- | /mœʁ/ |
| tu | meurs | meur- | /mœʁ/ |
| il / elle / on | meurt | meur- | /mœʁ/ |
| nous | mourons | mour- | /mu.ʁɔ̃/ |
| vous | mourez | mour- | /mu.ʁe/ |
| ils / elles | meurent | meur- | /mœʁ/ |
The eu / ou alternation reflects the historical stress pattern of French. In Old French, stressed o in an open syllable diphthongized into eu; unstressed o did not. The same pattern surfaces in pouvoir (peux / pouvons) and vouloir (veux / voulons) — three of the most-used boot-conjugated verbs in the language.
Je meurs de faim, on mange quand ?
I'm starving, when do we eat?
Il meurt à cinquante-trois ans, en pleine gloire.
He dies at fifty-three, at the height of his fame.
Les arbres meurent les uns après les autres à cause de la sécheresse.
The trees are dying one after another because of the drought.
Imparfait
The imparfait is built on the nous stem mour-, then takes regular endings throughout (no boot pattern in the imparfait — it uses one stem for all six forms).
| Person | Form |
|---|---|
| je | mourais |
| tu | mourais |
| il / elle / on | mourait |
| nous | mourions |
| vous | mouriez |
| ils / elles | mouraient |
Il mourait d'ennui dans cette réunion interminable.
He was dying of boredom in that endless meeting.
Les soldats mouraient par centaines à chaque assaut.
Soldiers were dying by the hundreds in each assault.
Passé simple (literary)
The passé simple uses the -us pattern (like courir, vivre, avoir).
| Person | Form |
|---|---|
| je | mourus |
| tu | mourus |
| il / elle / on | mourut |
| nous | mourûmes |
| vous | mourûtes |
| ils / elles | moururent |
Note the circumflex on mourûmes and mourûtes — required.
Il mourut sur le coup, sans souffrance.
He died instantly, without suffering. (literary)
Elle mourut en mille neuf cent vingt-trois, à l'âge de quatre-vingts ans.
She died in 1923, at the age of eighty. (literary / historical)
Futur simple — the double-r
The futur uses the third stem mourr- with double-r (note the o, not eu), plus the regular futur endings.
| Person | Form | Pronunciation |
|---|---|---|
| je | mourrai | /mu.ʁe/ |
| tu | mourras | /mu.ʁa/ |
| il / elle / on | mourra | /mu.ʁa/ |
| nous | mourrons | /mu.ʁɔ̃/ |
| vous | mourrez | /mu.ʁe/ |
| ils / elles | mourront | /mu.ʁɔ̃/ |
A note on the spelling: the futur and conditionnel of mourir use o, not eu — the form is mourrai /mu.ʁe/, parallel to courir → courrai. Don't be tempted to import the eu from the present je meurs; the futur stem reverts to mour- and then doubles the r.
On mourra tous un jour, autant en profiter maintenant.
We'll all die one day, might as well enjoy it now.
Si rien ne change, ces espèces mourront avant la fin du siècle.
If nothing changes, these species will die out before the end of the century.
Conditionnel présent
Same double-r stem mourr-, with the imparfait endings.
| Person | Form |
|---|---|
| je | mourrais |
| tu | mourrais |
| il / elle / on | mourrait |
| nous | mourrions |
| vous | mourriez |
| ils / elles | mourraient |
The conditional appears constantly in idiomatic exaggeration: je mourrais de honte (I'd die of shame), je mourrais pour un café (I'd die for a coffee).
Je mourrais pour un café là, tout de suite.
I'd kill for a coffee right now.
Sans toi, je mourrais d'ennui.
Without you, I'd die of boredom.
Subjonctif présent — the boot pattern returns
The subjunctive replicates the present boot pattern: stressed meur- in singular and 3pl, unstressed mour- in 1pl/2pl.
| Person | Form |
|---|---|
| (que) je | meure |
| (que) tu | meures |
| (qu')il / elle / on | meure |
| (que) nous | mourions |
| (que) vous | mouriez |
| (qu')ils / elles | meurent |
Je ne veux pas qu'il meure seul à l'hôpital.
I don't want him to die alone in the hospital.
Il faut qu'on meure tous, mais pas tout de suite.
We all have to die, but not right now.
Impératif
| Person | Form |
|---|---|
| (tu) | meurs |
| (nous) | mourons |
| (vous) | mourez |
The imperative of mourir is rare in literal use (you don't usually order someone to die), but appears in dramatic and rhetorical contexts.
« Meurs ! » crie le bandit dans le mauvais film.
\"Die!\" shouts the bandit in the bad film.
Participles and gérondif
- Participe passé: mort (with audible feminine: morte; plurals morts, mortes)
- Participe présent: mourant
- Gérondif: en mourant
The participle mort is special. It is one of the few French past participles where the feminine form is audibly different: mort /mɔʁ/ vs morte /mɔʁt/ — the final t is pronounced in the feminine. This makes participle agreement audible, unlike most participles where agreement is purely orthographic.
Elle est morte en mille neuf cent quatre-vingt-quinze.
She died in 1995.
Mes grands-parents sont morts à six mois d'intervalle.
My grandparents died six months apart.
Il est passé devant moi en mourant de rire.
He walked past me dying of laughter.
Mort is also a noun (la mort = death) and an adjective (un homme mort = a dead man). The triple categorization (participle, noun, adjective) sometimes blurs analysis, but the form is identical.
Compound tenses (with être)
Mourir takes être as its auxiliary. It is one of the maison d'être verbs because it marks a definitive change of state. Past participle mort agrees with the subject in gender and number.
Passé composé
être (présent) + mort(e)(s)
| Person | Form | Translation |
|---|---|---|
| je | suis mort(e) | I died |
| tu | es mort(e) | you died |
| il | est mort | he died |
| elle | est morte | she died |
| nous | sommes mort(e)s | we died |
| vous | êtes mort(e)(s) | you died |
| ils | sont morts | they died (m. or mixed) |
| elles | sont mortes | they died (f.) |

Trois personnes sont mortes dans l'accident.
Three people died in the accident.
Il est mort — past tense or adjective?
Crucial ambiguity: il est mort can mean either:
- He died (passé composé, the action) — Il est mort hier soir. = He died last night.
- He is dead (copula + adjective, the state) — Il est mort depuis dix ans. = He has been dead for ten years.
The two readings overlap because mort doubles as participle and adjective. Context disambiguates: a time-of-action adverb (hier, en 1923) signals reading 1; a duration adverb (depuis dix ans) signals reading 2. The same fusion exists in English ("he is dead" can describe a state or a recent event), but the grammatical analysis differs: French syncretism vs. English distinct lexical items (died vs dead).
Il est mort en 2010.
He died in 2010. (action)
Il est mort depuis longtemps maintenant.
He has been dead for a long time now. (state)

Comparison with English
Three friction points:
English has two words: die (action) and dead (state); French has one — mort. The fusion produces the il est mort ambiguity. Learn to read context: time-of-action adverbs signal "died"; duration adverbs signal "is dead."
English uses be dying to idiomatically; French uses mourir d'envie de, not mourir à. Je meurs à voir ce film is wrong. Je meurs d'envie de voir ce film.
The mourir de frame for figurative dying is far more productive in French than its English equivalent. English can say "dying of hunger / thirst / boredom" but quickly switches to other idioms ("I'm starving" rather than "I'm dying of hunger" in many contexts). In French, je meurs de faim is the default everyday phrasing.
Common Mistakes
Mistake 1: Using avoir in compound tenses.
❌ Il a mort hier soir.
Wrong — *mourir* takes *être*, and the participle is *mort* (not *mortu* either).
✅ Il est mort hier soir.
He died last night.
Mistake 2: Forgetting agreement on the participle.
❌ Elle est mort en 2010.
Wrong — with *être*, the participle agrees: feminine *morte*.
✅ Elle est morte en 2010.
She died in 2010.
Mistake 3: Single r in the futur or conditionnel.
❌ Je mourai sans regrets.
Wrong — *mourir* requires double-r in the futur.
✅ Je mourrai sans regrets.
I'll die without regrets.
Mistake 4: Wrong stem in nous / vous present.
❌ Nous meurons à petit feu.
Wrong — the *nous / vous* present uses *mour-*, not *meur-*.
✅ Nous mourons à petit feu.
We're dying a slow death.
Mistake 5: Using à instead of de for the dying-of construction.
❌ Je meurs à faim.
Wrong — the construction is *mourir DE* + cause.
✅ Je meurs de faim.
I'm starving.
Mistake 6: Using mourir for "kill" reflexively.
❌ Il s'est mouri.
Wrong — *mourir* is not pronominal. For 'kill oneself' use *se tuer* or *se suicider*.
✅ Il s'est tué dans un accident.
He died in an accident (literally: killed himself, used impersonally for accidents).
Key takeaways
Mourir is a 3e-groupe -ir verb meaning to die, with a famously irregular paradigm built on three stems: stressed meur- (je meurs, il meurt, ils meurent), unstressed mour- (nous mourons, mourais, mourant), and double-r mourr- (futur and conditionnel: je mourrai, je mourrais).
It takes être in compound tenses (il est mort, elle est morte, ils sont morts) — one of the maison d'être verbs. The past participle mort has audible feminine and plural agreement (mort / morte / morts / mortes), and doubles as a noun (la mort = death) and adjective.
The most productive idiomatic frame is mourir de + cause — mourir de faim, de rire, d'ennui, d'envie — used constantly in colloquial speech for figurative dying. The headline orthographic feature is the double-r in the futur and conditionnel (je mourrai, je mourrais), which it shares with courir and acquérir.
