How to Say I'm Tired in French: Je Suis Fatigué

It's 11 p.m., you've been sightseeing since dawn, and your French host asks if you want one more glass of wine. You want to say "I'm tired" and head to bed, but "Je suis tired" won't get you far. Here's how to say I'm tired in French, naturally and politely.

Why "I'm Tired" Needs More Than One Phrase

English gets by with one word: tired. French has several, and they change with how tired you are and who you're talking to. Saying "I'm tired" in French can mean you're sleepy, worn out, or fed up, and each has its own phrase.

That matters on a trip or in a chat with a French friend. Say the wrong one and you might sound like you're ill, or like you're bored. This guide gives you the standard way to say I'm tired in French, the casual slang, and the polite phrases for ending an evening gracefully.

The Standard Way: Je Suis Fatigué(e)

The everyday answer is "Je suis fatigué" (I'm tired). Unlike j'ai faim, this one does use être (to be), so the English logic works for once. The word is an adjective, so it agrees with the person speaking.

Key Phrases

• Je suis fatigué (zhuh swee fah-tee-gay) — I'm tired (said by a man)
• Je suis fatiguée (zhuh swee fah-tee-gay) — I'm tired (said by a woman)
• Je suis épuisé(e) (zhuh swee zay-pwee-zay) — I'm exhausted
• Je suis crevé(e) (zhuh swee kruh-vay) — I'm wiped out (casual slang)
• J'ai sommeil (zhay soh-may) — I'm sleepy
• Je tombe de sommeil (zhuh tohm duh soh-may) — I'm falling asleep on my feet

Grammar Note

Fatigué ends in -é for a man and adds an extra -e for a woman: fatiguée. Both sound identical, so this only matters when you write. In the plural, add -s: nous sommes fatigués.

• Mistake: J'ai fatigué — this is not a French sentence. Use je suis fatigué.
• Mistake: Je suis fatigué de + noun when you mean "tired from": say fatigué par the trip, or fatigué après the trip.

Tired vs. Sleepy: Fatigué or Sommeil?

This is the distinction that trips up most learners. Être fatigué describes your general energy: you've worked hard, walked all day, or slept badly. Avoir sommeil means you actually want to sleep right now, and like avoir faim, it uses avoir (to have) because French says you "have sleepiness."

• Je suis fatigué mais je n'ai pas sommeil. (I'm tired but I'm not sleepy.)
• Les enfants ont sommeil. (The kids are sleepy.)
• Tu as l'air fatigué. (You look tired.)

French people often blame le décalage horaire (jet lag) or la fatigue de la semaine (the week's tiredness) when they turn down an invitation. It's a perfectly accepted excuse, and no one will push you to stay out.

Stronger and Slangier Ways to Say It

When fatigué isn't enough, French has a full ladder of options. Pick the rung that matches your mood and your audience.

• Je suis claqué(e) (zhuh swee klah-kay) — I'm shattered (casual)
• Je suis lessivé(e) (zhuh swee leh-see-vay) — I'm washed out, literally "laundered"
• Je n'en peux plus (zhuh nahn puh plew) — I can't take any more
• Je suis mort(e) de fatigue (zhuh swee mor duh fah-teeg) — I'm dead tired

Use crevé, claqué and lessivé with friends and family. With a boss or a host you've just met, stay with fatigué or épuisé. The phrase je suis mort de fatigue sounds dramatic, but French speakers use it all the time without anyone worrying.

Polite Ways to Call It a Night

Sometimes you don't just want to say you're tired, you want to leave. French has gentle ways to do that.

• Je vais me coucher. (I'm going to bed.)
• Je vais aller dormir. (I'm going to go sleep.)
• Je commence à fatiguer. (I'm starting to flag.)
• Je suis désolé, je suis un peu fatigué ce soir. (I'm sorry, I'm a bit tired tonight.)

Adding un peu (a bit) and ce soir (tonight) softens the message, so it sounds like a fact about your evening rather than a complaint about the company. Finish with bonne nuit and you've exited like a local.

Practical Application

Here's a short exchange you might really have after a long day of travel:

• Step 1: Your host asks Tu veux un dessert ? (Do you want a dessert?)
• Step 2: Answer Non merci, je suis un peu fatigué ce soir. (No thanks, I'm a bit tired tonight.)
• Step 3: Add Je vais aller me coucher. (I'm going to bed.)
• Step 4: Close with Bonne nuit, à demain ! (Good night, see you tomorrow!)

Practice Exercises

• Translate into French (you are a woman): I'm tired.
• Fill in the blank: Les enfants ___ sommeil. (avoir, present tense)
• Multiple choice: Which means "I'm exhausted"? (a) Je suis épuisé (b) J'ai épuisé (c) Je fais épuisé
• Translate into French: I'm tired but I'm not sleepy.
• Which is slang: je suis crevé or je suis fatigué ?

Answer Key

• Je suis fatiguée.
• ont (les enfants ont sommeil)
• (a) Je suis épuisé.
• Je suis fatigué(e) mais je n'ai pas sommeil.
• Je suis crevé is the slang one.

Conclusion and Next Steps

Key takeaways:

• Use je suis fatigué(e) for "I'm tired", and add an extra -e if you're a woman.
• Use avoir sommeil (not être) when you mean sleepy.
• Keep crevé, claqué and lessivé for friends, and soften goodbyes with un peu and ce soir.
