Faux amis (false friends with English)

Summary

Faux amis look like English words but mean something different, or even the opposite — actuellement means "currently", not "actually"; librairie means "bookshop", not "library".

Explanation

A faux ami ("false friend") is a word that looks or sounds like an English word — often because both descend from the same Latin root — but has drifted to a different meaning in one or both languages. False friends are dangerous precisely because they don't feel like new vocabulary: the word looks familiar, so learners import the English meaning by reflex and produce a sentence that is grammatically perfect but means something else, or nothing at all, to a French listener.

The trap runs in both directions. Sometimes the French word covers a narrower or shifted sense of a shared root (actuellement = "currently, at present", not "actually"; éventuellement = "possibly, if need be", not "eventually"). Sometimes it is a near-total swap, so the two words are almost opposites in practice: décevoir looks like "to deceive" but means "to disappoint"; to actually deceive someone in French is tromper. And sometimes the French word simply denotes a different real-world thing: une librairie is a bookshop (you buy books there), while a lending library is une bibliothèque.

Ten worth drilling: actuellement = currently (not "actually", which is en fait); éventuellement = possibly (not "eventually", which is finalement); rester = to stay/remain (not "to rest", which is se reposer); attendre = to wait for (not "to attend", which is assister à); librairie = bookshop (not "library", which is bibliothèque); monnaie = change/coins (not "money" in general, which is argent); sensible = sensitive (not "sensible", which is raisonnable or sensé); prétendre = to claim (not "to pretend", which is faire semblant); décevoir = to disappoint (not "to deceive", which is tromper); demander = to ask (not "to demand", which is exiger). A closely related pair: passer un examen means to TAKE an exam (sit it), while réussir un examen means to PASS it — passer alone says nothing about the result.

Each of these produces a distinctive, recognisable error. "Je vais attendre la réunion" sounds to a French ear like "I am going to wait for the meeting" — fine if that's the intent, but wrong if the learner meant "attend" in the sense of "be present at", which needs assister à la réunion. "Il est très sensible à la critique" does not mean he is a sensible, level-headed person about criticism; it means he is emotionally sensitive to it — thin-skinned, easily hurt. "J'ai passé mon examen hier" only tells you the exam happened yesterday, not whether the speaker passed; that requires j'ai réussi mon examen.

Rule of thumb: when a French word looks suspiciously like an easy English cognate, treat that as a warning sign rather than reassurance, and check it — especially with common, high-frequency verbs like rester, attendre, demander, and adjectives like sensible. Genuine cognates exist too (nation, télévision, université behave as expected), so the goal is not to distrust every look-alike, but to specifically double-check the handful of famous faux amis, since a single wrong one can flip the meaning of a sentence.

A useful habit is to learn faux amis in pairs: the French word with its real meaning, alongside the French word that actually expresses the English sense you were reaching for (décevoir/tromper, rester/se reposer, attendre/assister à, librairie/bibliothèque, monnaie/argent, sensible/raisonnable-sensé, prétendre/faire semblant, demander/exiger, actuellement/en fait, éventuellement/finalement). Reviewing the pair together, rather than each word in isolation, is what keeps the two meanings from blurring back together.

Examples

Actuellement, elle habite à Lyon. — Currently, she lives in Lyon. (actuellement = currently, not "actually" (en fait).)

Il faut réserver, mais on peut éventuellement annuler. — You have to book, but you can possibly cancel. (éventuellement = possibly, not "eventually" (finalement).)

Je vais rester à la maison ce soir. — I'm going to stay home tonight. (rester = to stay, not "to rest" (se reposer).)

Tu peux m'attendre devant la librairie ? — Can you wait for me in front of the bookshop? (attendre = to wait for; librairie = bookshop, not "library" (bibliothèque).)

Il est très sensible à la critique, même quand elle est raisonnable. — He is very sensitive to criticism, even when it is sensible. (sensible = sensitive; "sensible" (level-headed) = raisonnable/sensé.)

Elle a passé son examen hier, mais je ne sais pas si elle l'a réussi. — She took her exam yesterday, but I don't know if she passed it. (passer un examen = to take it; réussir un examen = to pass it.)
