French False Friends: 20 Words That Don't Mean What They Look Like
A false friend is a French word that looks like an English word but means something different — the classic false cognate. Around a third of English vocabulary arrived through French, so French speakers get thousands of words for free — plus a short, treacherous list of words that only look free. Here are the 20 that most often slip into French speakers' English drafts, each with the exact error it produces.

Why false friends survive grammar checkers
«I passed my exam and rested in Paris for three days.» — the writer took the exam (result unknown) and stayed in Paris — grammatical, and misleading twice. The sentence parses perfectly: every word is real English in a valid position, so a conventional grammar checker has nothing to flag. The mistake lives one level down, in meaning — the word-level face of what linguists call L1 interference.
That is why false friends are caught by knowledge, not by parsing. Diglot's grammar checker for French speakers reviews drafts against known French-to-English transfer patterns — including the meaning-level slips on this page — and explains each fix instead of silently rewriting you. And when the English word will not come at all, Diglot Weave for French lets you type the French word mid-sentence and pick the English translation right where you typed.
French false friends — questions
What is a false friend in French?
A French word that looks like an English word but means something different — for example, librairie looks like «library» but means bookshop. Linguists call these false cognates: the resemblance is accidental, or the shared ancestor drifted apart, so the English lookalike says something the writer never intended.
Why do grammar checkers miss false friends?
Because the sentence stays grammatical. «I passed my exam and rested in Paris for three days.» parses perfectly — every word is real English in a valid position — but the writer took the exam (result unknown) and stayed in Paris — grammatical, and misleading twice. The error lives at the meaning level, so a checker that only inspects syntax has nothing to flag. Catching it takes knowledge of which French words leak into English with the wrong meaning.
What are the most common French false friends?
The highest-frequency ones on this page are librairie (means bookshop, not «library»); actuellement (means currently, not «actually»); demander (means to ask, not «demand»); éventuellement (means possibly, not «eventually»); sensible (means sensitive, not «sensible»). All 20 entries above appear regularly in real French-speaker drafts.
How do I stop making false-friend mistakes in English?
Learn the short list — each language has only a few dozen high-frequency false friends, and the 20 on this page cover the ones that actually surface in French speakers' writing. Then review your English with a tool that knows French-to-English transfer patterns, not just grammar rules: false friends are meaning errors, and meaning-level review is what catches them.
