FAQ: French Numbers
It’s a common question — especially when you reach numbers like quatre-vingt-dix-huit (98).
We explain the whole logic behind it in this section.
Hint: blame the old base-20 system that the French still use today.
French numbers are usually written as either:
- one word (onze, quarante), or
- hyphenated combinations (vingt-deux, soixante-quinze).
Some tips:
- For numbers like 21, 31, 41 — use et: vingt-et-un, trente-et-un.
- In writing, commas are used instead of decimal points (e.g. 2,5 = two and a half).
- Big numbers often use spaces instead of commas: 1 000 (not 1,000).
French phone numbers are grouped in pairs of digits:
- Example: 06 12 34 56 78
This format is standard across France and helps with clear pronunciation when speaking.
French pronunciation can be tricky at first — especially with nasal vowels and linked sounds (liaison).
For example:
- dix-huit → [dee-zweet]
- vingt-et-un → [vɛ̃-t‿e-œ̃]

Numbers themselves don’t have gender.
But the words they describe do:
- un garçon (a boy) — masculine
- une fille (a girl) — feminine
So the number agrees with the noun, not the other way around.
Yes — in France, children are taught the same math-like system (soixante-dix, quatre-vingts, etc).
However, in Belgium and Switzerland, they often learn simpler alternatives like septante (70) and nonante (90).
A mix of practice methods works best:
- Repetition and listening (especially for tricky 70–99)
- Quizzes to test recognition
- Saying numbers in context (age, money, dates)
Try shadowing with native speakers — it helps lock in the rhythm naturally.
