English has one word for “people”; French spreads the job across three — and picks them by COUNTING. Les gens can’t be counted, personnes exists to be counted, and du monde measures the crowd. Here’s the sorting machine.
The quick version — the full lesson is below. More shorts →
Plural-only, never with a number: Les gens sont sympas ici. (People are nice here.) Beaucoup de gens pensent que… Vague quantities are fine (beaucoup de, peu de, la plupart des gens) — precise numbers are not.
The moment a number appears, switch: une table pour quatre personnes, trois personnes attendent. « Trois gens » is the error that instantly flags a learner — numbers demand personnes. (Bonus: personne alone, with ne, means NOBODY: Je ne vois personne.)
To say how busy a place is, French measures “world”: Il y a du monde ! (It’s crowded!) Il y avait beaucoup de monde au marché. And of course tout le monde = everyone — grammatically singular, as covered in the tout lesson.
| You want to say | Use | Example |
|---|---|---|
| people in general | les gens | Les gens adorent ce café. |
| N people | N personnes | Nous sommes cinq personnes. |
| a crowd / “busy” | du monde | Il y a trop de monde. |
| everyone | tout le monde | Tout le monde est là. |
| people = “one/you” | on | En France, on dîne tard. |
No — that’s the whole division of labour: gens is the uncountable mass, personnes the countable unit. Des milliers de gens works (vague thousands); « mille gens » doesn’t.
Un peuple = a people, a nation (le peuple français). Using it for “people around town” sounds like a political speech.
Always: Paul est une personne intéressante. Grammatical gender ≠ real-world gender — same as une victime, une star. More in noun gender.
The last row of the table deserves its own lesson: on, the most French pronoun of all.
