Calques are English structures you've carried into French. The words are right, but the grammar is English. The 30 below are the most common — every single one of them will make a French person silently switch to English. After 25 years of teaching, these are the patterns that never change.
What is a calque, exactly?
A calque is a structure you've borrowed from English. The words you choose are correct French words — that's what makes calques so hard to catch. The problem isn't vocabulary. It's grammar and structure.
When an English speaker says "Je suis 25 ans" instead of "J'ai 25 ans", the words je, suis, 25, ans are all correct French words. The structure is English. You've used the English verb "to be" the way you would in English — but French uses avoir for age. That's a calque.
It's not a mistake. It's a footprint of English left in your French. The fix isn't to learn more vocabulary. It's to unlearn the English structure — and replace it with the French one.
The verb that splits English and French in half
English uses "I am" for almost everything. French splits those uses between être and avoir. This is the single biggest source of calques.
Age: Je suis 25 ans ❌ → J'ai 25 ans ✓. Hunger: Je suis faim ❌ → J'ai faim ✓. Cold (the feeling): Je suis froid ❌ → J'ai froid ✓. Fear: Je suis peur ❌ → J'ai peur ✓. Sleepiness: Je suis sommeil ❌ → J'ai sommeil ✓.
The pattern is simple: in French, physical states and age use avoir, not être. If you memorize this one rule, you eliminate the most common calque in the language.
Politeness you can't translate literally
English says "I want a coffee." French says "Je voudrais un café." The first is technically correct, but the second is what French people say. The difference: the conditional.
When you ask a stranger for something — a coffee, the menu, a favour, directions — French uses the conditional (je voudrais, vous pourriez, auriez-vous) or the polite "vous pouvez...?" construction. Je veux sounds abrupt; it works between friends, but not with a waiter.
This isn't about being "fake polite". It's how the language is built. The conditional is built into French the way "would you mind...?" is built into English. Use it.
The most embarrassing calque (and how to avoid it)
In English, you say "I'm excited." If you translate that literally into French, you say "Je suis excité."
In French, excité means sexually aroused. Always. It is not a synonym for "excited" or "enthusiastic". This is the single most common — and most embarrassing — calque in the language. French people hear it constantly. Almost nobody corrects it. Don't be the next.
For "I'm excited" or "I'm enthusiastic", use je suis enthousiaste, je suis content, or simply ça me fait plaisir. For "I'm looking forward to it", use j'ai hâte — literally "I have haste" — which works in both English and French.
How to stop making calques
You don't stop making calques by reading more grammar. You stop by replacing the structure in your mouth. The calque "je suis 25 ans" is a habit of speech, not a gap in knowledge. You need to break the habit.
The Echo Bounce method works for this. Pick a calque you keep making. Listen to a native speaker say the correct form five times. Record yourself saying it. Play it back. Compare. Repeat five times. The calque starts to disappear in two to three weeks of daily practice.
