25 French–English False Friends That Will Embarrass You
préservatif ≠ preservative, excité ≠ excited, librairie ≠ library. 25 French words that look like English, mean something else entirely — including five that will genuinely make you blush.
You're mid-sentence, feeling good. The French word is right there, it looks exactly like the English one, so you reach for it without thinking—and that's the moment it betrays you. You meant to say you were excited. You just told the room you were something else entirely.
These are faux amis—"false friends." The name isn't a metaphor a teacher invented; it's the actual term two linguists coined back in 1928 for words that look like a bridge between two languages and turn out to be a trapdoor[1]. And here's why they're stickier than ordinary vocabulary: a word you've never seen makes your brain slow down and check. A word that looks familiar makes it speed up and skip the check[2]. That confidence is exactly what gets you.
Below are 25 of the ones most likely to trip you—starting with the five that will actually make you blush.
The five that will actually embarrass you
— Looks like preservative. Means condom. Ask a French waiter whether the jam contains any préservatifs and you've asked something very different from what you intended. (Preservative = un conservateur.)
— Looks like excited. Means aroused, or at best over-worked-up. Je suis excité pour le concert does not say "I can't wait for the concert"—for that, use j'ai hâte or je suis impatient.
— As a noun, un baiser is a sweet, innocent kiss. As a verb, baiser is extremely vulgar slang for having sex. To say you kissed someone, use embrasser. This one word has ended more first dates than any grammar mistake ever could.
— Avoir envie de means to want / to fancy something. Harmless with a coffee: j'ai envie d'un café. Considerably less harmless with a person: j'ai envie de toi means "I want you." Choose your objects carefully.
— Looks like introduce. Means to insert / to bring in. You do not introduire your friend to your parents—you présenter them. Say je voudrais vous introduire and you've suggested something anatomical.
The everyday confusions
These won't get you in trouble—just quietly misunderstood.
— arm. (A bra is un soutien-gorge.)
— bread, not suffering. J'adore le pain is a love of carbs, not agony.
— corner. The coin in your pocket is une pièce.
— loose change / coins. Money in general is l'argent. Ask for monnaie and you'll get shrapnel, not a salary.
— a bookshop, where you buy books. A library you borrow from is une bibliothèque.
— a day (the span of one). A journey is un voyage or un trajet.
— a jacket. A vest is un gilet (or un maillot de corps for the undershirt).
— for a person, it means tall, not impressive. Un homme grand is a tall man; un grand homme is a great one. Word order flips the meaning.
The sneaky verbs
Verbs are the worst offenders, because you're usually moving fast when you use them.
— to attend (a meeting, a concert), not to assist. J'ai assisté à la réunion = I was there, not that I helped run it.
— to wait for. Je t'attends = I'm waiting for you, not attending to you.
— to ask, not to demand. It's polite. To actually demand something is exiger.
— to stay / remain. Je reste à la maison = I'm staying home, not resting. To rest is se reposer.
— to claim / assert. Il prétend être médecin = he claims to be a doctor. To pretend (playact) is faire semblant.
— to wound / hurt, not to bless. Tu m'as blessé = you hurt me. To bless is bénir.
— to sit / take an exam. It says nothing about whether you did well. To pass it is réussir un examen—so "j'ai passé l'examen" from a nervous student means only that they showed up.
The Latin-looking words that lie
The abstract, sophisticated-sounding words feel the most trustworthy. Don't trust them.
— currently, right now. Not "actually." (Actually = en fait, en réalité.)
— possibly, if need be. Not "eventually." (Eventually = finalement, à terme, tôt ou tard.) This pair reverses a whole plan: "on le fera éventuellement" means "we might do it," not "we'll get around to it."
— sensitive, emotionally or physically. A personne sensible cries at films. Someone level-headed is raisonnable or sensé.
(sympa) — nice, likeable. Calling someone sympa says they're pleasant, not that they feel sorry for you. Sympathetic = compatissant.
— disappointment, not deception. Quelle déception = what a letdown. Deception (a lie) is une tromperie.
Why "just memorize them" never quite works
Here's the frustrating part: you can read this list, nod along, feel like you've got it—and still say je suis excité three weeks from now in the exact moment it matters. False friends aren't a knowledge problem. You already know the right answer. They're a reflex problem: under the pressure of real conversation, your brain grabs the word that looks safest, and the look-alike wins[2].
Reflexes don't respond to lists. They respond to repetition in context—seeing actuellement in a real sentence enough times that "currently," not "actually," is the meaning that fires first.
That's where the Flashcards (SRS) system in Français Flow does the quiet work. Add each false friend as its own card—excité → aroused, not excited—and the spaced-repetition schedule brings it back exactly as often as you need: rarely once it's solid, relentlessly while it isn't. The correction stops being something you know and becomes something that just fires.
And there's one mode built for words like these. Practice Hard pulls the cards with your worst accuracy—and false friends live there almost by definition, because they're the ones your brain keeps confidently getting wrong. Sort Weakest first, run that deck for ten minutes, and you're drilling precisely the traps that are still catching you, not the words you already own.
Quick gut check—no peeking:
Did it stick?
A few quick questions — no pressure.
1Dinner's ready and you want to say you're excited to eat. What actually works?
2You need directions to a place to buy a novel. Where do you ask for?
3A nervous student says « j'ai passé l'examen ». What did they actually tell you?
4Is sympathique safe for telling a French friend they're lovely and kind?
5You want to ask whether the jam contains preservatives. Which word do you need?
