French Idioms and Expressions: 25 Sayings French People Actually Use

French idioms and expressions are the fastest shortcut to understanding real spoken French because they appear constantly in everyday conversation, headlines, and movie dialogue, and their meaning is often not literal. Below you will learn 25 idioms French people actually use, with English-friendly pronunciations, natural examples, and cultural notes so you can recognize them instantly and use them without sounding forced.

Why French idioms matter (especially for movies and TV)

French is spoken by hundreds of millions of people worldwide. The Organisation internationale de la Francophonie estimates around 321 million French speakers, across 50-plus countries and territories where French is used to varying degrees in public life and education (OIF, 2022).

Ethnologue also lists French as one of the world’s major languages by total speakers, with wide geographic spread (Ethnologue, 2024). That spread matters because idioms travel well, but their vibe can shift between France, Belgium, Switzerland, and francophone Africa.

Idioms are also “high compression” language. One short phrase can carry attitude, humor, and social positioning, which is exactly what scriptwriters rely on.

"Idioms are cultural fossils: they preserve old images and social habits, even when speakers no longer notice them."

Professor Anna Wierzbicka, linguist and author of Cross-Cultural Pragmatics (2003)

If you learn idioms through short scenes, you also learn timing. That is why Wordy focuses on real clips: you hear the idiom in a believable situation, not as a vocabulary list.

If you are building your basics first, pair this with how to say hello in French so you can open conversations naturally before you start dropping idioms.

Pick 5 idioms that match your life. Use them for one week in messages or self-talk, then rotate.

Keep the grammar around the idiom simple. The idiom is already doing the heavy lifting, so do not add fancy structures on top.

25 French idioms and expressions (with pronunciation and real usage)

avoir le cafard

Pronunciation: "ah-VWAHR luh kah-FAR"

Meaning: to feel down, blue, or gloomy. Literally it is “to have the cockroach,” which sounds odd in English but feels normal in French.

Example: "Depuis hier, j’ai le cafard." Translation: "Since yesterday, I’ve been feeling down."

Cultural note: This is common in films when a character is quietly spiraling. It is more “sad and heavy” than “stressed.”

en avoir marre

Pronunciation: "ahn ah-VWAHR MAR"

Meaning: to be fed up. It is blunt and very common.

Example: "J’en ai marre de ce boulot." Translation: "I’m fed up with this job."

Register: casual to slang depending on tone. In a formal setting, soften it with "Je suis fatigué(e) de..." (pronounced "zhuh swee fah-tee-GAY").

coûter les yeux de la tête

Pronunciation: "koo-TAY lay zyuh duh lah TET"

Meaning: to cost a fortune, literally “to cost the eyes of the head.”

Example: "À Paris, les loyers coûtent les yeux de la tête." Translation: "In Paris, rent costs a fortune."

Cultural note: You will hear this in consumer conversations: rent, tickets, groceries, repairs. It fits France’s strong “complaining as bonding” culture.

tomber dans les pommes

Pronunciation: "tohn-BAY dahn lay POM"

Meaning: to faint, literally “to fall into the apples.”

Example: "Elle est tombée dans les pommes." Translation: "She fainted."

Usage tip: It is common, but do not use it in medical contexts. In a hospital scene, characters often switch to "s’évanouir" (pronounced "say-vah-NWEER").

avoir la flemme

Pronunciation: "ah-VWAHR lah FLEM"

Meaning: to not feel like doing something, to be lazy in the moment.

Example: "J’ai la flemme de sortir." Translation: "I can’t be bothered to go out."

Cultural note: This is peak everyday French. It is relatable, slightly self-mocking, and very common among friends.

poser un lapin

Pronunciation: "poh-ZAY uhn lah-PAN"

Meaning: to stand someone up, literally “to put down a rabbit.”

Example: "Il m’a posé un lapin." Translation: "He stood me up."

Dating context: This shows up constantly in rom-coms. It is more specific than “cancel,” it implies you waited and they did not show.

avoir un coup de foudre

Pronunciation: "ah-VWAHR uhn koo duh FOODR"

Meaning: love at first sight, literally “a lightning strike.”

Example: "Ça a été le coup de foudre." Translation: "It was love at first sight."

If you want romantic language beyond idioms, combine this with how to say I love you in French to match the relationship stage.

être au bout du rouleau

Pronunciation: "ETR oh boo doo roo-LOH"

Meaning: to be exhausted, at the end of your rope.

Example: "Je suis au bout du rouleau." Translation: "I’m completely worn out."

Cultural note: This is common in workplace dramas. It signals burnout, not just “tired.”

avoir la pêche

Pronunciation: "ah-VWAHR lah PESH"

Meaning: to feel great, full of energy. Literally “to have the peach.”

Meaning: it’s doing my head in, it’s annoying or stressing me out.

Meaning: to be very lazy, literally “to have a hair in the hand.”

Example: "Attends, j’ai un chat dans la gorge." Translation: "Wait, I have a frog in my throat."

Meaning: to have a lot to do, literally “bread on the board.”

Example: "Cette semaine, j’ai du pain sur la planche." Translation: "This week, I’ve got a lot on my plate."

Example: "Le film est sympa, mais ça ne casse pas trois pattes à un canard." Translation: "The movie is nice, but it’s nothing special."

Usage tip: Long idioms like this are great for listening practice. In real speech, French speakers often say it quickly as one chunk.

tenir au courant

Pronunciation: "tuh-NEER oh koo-RAHN"

Meaning: to keep someone posted, keep them informed.

Example: "Je te tiens au courant." Translation: "I’ll keep you posted."

Register: polite-neutral, safe in professional settings. The Académie française often recommends clear, precise French in public communication, and this is a clean, standard option (Académie française, "Dire, ne pas dire").

Patterns you will start noticing (and why they help)

Food metaphors are everywhere

You saw "pétrin," "pâte," "pain," and "assiette." Food idioms are common because they are concrete and shared culturally.

France also has strong regional food identities, so food imagery feels natural and emotionally “close,” even in abstract situations.

Animals show up, but not always as insults

"Chat dans la gorge" is neutral. "Canard" in the duck idiom is playful.

When animals become insults, the register shifts fast. If you are curious about stronger language boundaries, read our guide to French swear words so you know what not to repeat from edgy scenes.

Many idioms are “fixed chunks”

You cannot freely swap words. For example, it is "poser un lapin," not "poser un chien."

This is why learning from clips works: you memorize the chunk with rhythm, not as a grammar exercise.

How to learn idioms with movie and TV clips (a practical routine)

1. Watch the clip with subtitles once. Focus on the situation and emotion.

2. Replay and shadow the idiom line. Copy the speed and melody, not just the words.

3. Save the idiom with one example sentence. Keep it short and personal.

4. Use it within 24 hours. A message to a friend is enough: "J’ai la flemme ce soir."

If you also want natural openings and endings for scenes, pair idioms with how to say goodbye in French. That combination makes your French sound “complete,” not like isolated phrases.

Common mistakes learners make (and how to avoid them)

Translating idioms word-for-word into English

If you say "I have the cockroach" in English, it will confuse people. Treat idioms as separate vocabulary items.

Use a dictionary resource like CNRTL to verify meaning and usage notes when an idiom feels unclear (CNRTL, accessed 2026).

Using slang idioms too early

Slang can sound performative if your pronunciation and timing are not solid yet. Start with neutral idioms like "tenir au courant," "ne pas être dans son assiette," and "avoir du pain sur la planche."

Overusing idioms in formal situations

Idioms are powerful, but too many can sound theatrical. In professional French, one idiom per conversation is plenty.

If you want to polish your overall sound, bookmark our French pronunciation guide and practice the nasal vowels in words like "courant" (koo-RAHN) and "pain" (PAN).

A compact cheat sheet (neutral vs casual)

Keep going: build an idiom habit

Idioms are not a “finish line,” they are a signal that you are listening like a native speaker. Once you recognize them, French dialogue becomes less mysterious and more predictable.

For a fun next step, learn greetings that pair naturally with idioms in real scenes, starting with how to say hello in French. Then explore the sharper edge of informal French with our French swear words guide, but treat it as comprehension-first, not a script to copy.
