French is often considered the language of love, elegance, and cuisine—but it’s also full of oddities, history, and fun facts that might surprise even fluent speakers. From words that don’t exist in English to tongue-twisting pronunciations and grammatical peculiarities, the French language is a fascinating labyrinth. Whether you’re a language learner, a Francophile, or just curious, here are some fun and strange facts about the French language that will make you say, “Oh là là!”
1. French Was the Official Language of England (Yes, Really!)
It might sound strange, but after William the Conqueror invaded England in 1066, French became the language of the English court, government, and upper classes for about 300 years. This period, known as the Norman rule, significantly influenced the English language. That’s why modern English has so many French-derived words like court, justice, judge, army, and ballet.
2. There’s No Word for “Eighty” (Sort Of)
The French language takes an unusual approach to numbers, particularly in the 70s, 80s, and 90s. While most languages use a logical base-10 system (like soixante = 60, septante = 70), French sticks to a form of math in its numbers. For example:
- 70 = soixante-dix (60 + 10)
- 80 = quatre-vingts (4 x 20)
- 90 = quatre-vingt-dix (4 x 20 + 10)
Imagine doing math every time you say a number. Belgium and Switzerland do it differently, using septante, octante, and nonante, which makes a lot more sense—but isn’t standard in France.
3. The Longest Word Has 25 Letters
The longest word in the French dictionary is “anticonstitutionnellement”, which means “in an unconstitutional manner.” It has 25 letters and 11 syllables. While it may not pop up in casual conversation, it’s a favorite of French teachers everywhere trying to impress (or intimidate) students.
4. French Has Gendered Nouns (And It’s Not Always Logical)
One of the first challenges French learners face is that all nouns have a gender—masculine or feminine. But why is a chair (chaise) feminine and a pencil (crayon) masculine? There’s often no logic, and it’s a headache for learners. Even worse, adjectives and articles have to agree with the noun’s gender, making grammar much more complex than in English.
5. You Can Say “Yes” and “No” at the Same Time
The French word “Si” is used when responding “yes” to a negative question—something English doesn’t do. For example:
- Tu n’aimes pas le chocolat ? (Don’t you like chocolate?)
- Si ! J’adore ça. (Yes [I do]! I love it.)
It’s a very specific word with no direct translation in English, and it’s a perfect example of the subtlety and nuance in French conversation.
6. The French Academy Regulates the Language
The Académie Française (French Academy), founded in 1635, is responsible for guarding the purity of the French language. This institution decides what words are officially recognized and works to prevent foreign words—especially English ones—from entering the language. They even propose French alternatives to tech terms like:
- Email → courriel
- Smartphone → téléphone intelligent
- Hashtag → mot-dièse
Still, many people ignore these rules and use English words anyway while learn French in France .
7. French Used to Have More Letters
Old French had several letters that no longer exist, like the long s (ſ) and various ligatures. Even today, you might see the ligature œ in words like sœur (sister) or cœur (heart). It’s a holdover from Latin and adds to French’s old-world charm—and spelling challenges.
8. There Are Words That Only Exist in French
Some French words describe feelings or concepts so specific they have no exact English equivalent. For example:
- Dépaysement – the feeling of being out of your country or cultural element.
- Retrouvailles – the joy of reuniting with someone after a long time.
- Flâner – to stroll aimlessly, soaking in the atmosphere.
These words reflect the French love of subtle emotion and poetry in everyday life.
9. It’s One of the Most Spoken Languages Worldwide
French is spoken on five continents and is an official language in 29 countries. It’s one of the working languages of the UN, the EU, the African Union, NATO, and the International Olympic Committee. French isn’t just for Parisians sipping espresso—it’s a global language with over 300 million speakers.
10. There’s a Tongue-Twister Involving a Hedgehog
French has some great tongue-twisters, and one of the most delightful is:
“Un chasseur sachant chasser sait chasser sans son chien.”
(A hunter who knows how to hunt knows how to hunt without his dog.)
Another fun one:
“Si mon tonton tond ton tonton, ton tonton sera tondu.”
(If my uncle shaves your uncle, your uncle will be shaved.)
Practicing these can help with pronunciation—and cause laughter-induced hiccups.
