French Numbers 1 to 100: The Complete Guide with Rules and Pronunciation

Mastering numbers is an essential milestone in your French learning journey. From ordering deux baguettes at the local bakery to understanding train platform announcements or exchanging contact numbers, French numbers are part of daily communication.

While counting from 1 to 69 is remarkably straightforward, numbers from 70 to 99 carry a historical quirk that confuses many beginners. In this guide from my-french.com, you will learn how the system works, understand pronunciation secrets, and count with total confidence.

1. The Core Building Blocks: Numbers 1 to 19

Memorizing the first twenty numbers gives you the foundation for almost every number in the language.

1 to 10: The Unit Digits

  • 1 : un (masculine) / une (feminine)
  • 2 : deux
  • 3 : trois
  • 4 : quatre
  • 5 : cinq
  • 6 : six
  • 7 : sept (the "p" is completely silent)
  • 8 : huit
  • 9 : neuf
  • 10 : dix

    • 11 to 19: The Irregular Teens

  • 11 : onze
  • 12 : douze
  • 13 : treize
  • 14 : quatorze
  • 15 : quinze
  • 16 : seize

    • From 11 through 16, numbers end in the suffix -ze:

  • 17 : dix-sept
  • 18 : dix-huit
  • 19 : dix-neuf

    • From 17 to 19, French switches to a simple compound formula (10 + unit):

    2. Straightforward Logic: Numbers 20 to 69

This section works identically to English: you learn the tens word and attach the units.

  • 20 : vingt
  • 30 : trente
  • 40 : quarante
  • 50 : cinquante
  • 60 : soixante

    • The Rule of "et un"

  • 21 = vingt-et-un
  • 31 = trente-et-un
  • 41 = quarante-et-un
  • 51 = cinquante-et-un
  • 61 = soixante-et-un

    • When adding "1" to any of these tens, French inserts the word et (and):

  • 22 : vingt-deux
  • 37 : trente-sept
  • 54 : cinquante-quatre
  • 68 : soixante-huit

    • For units 2 through 9, simply connect the tens word and the unit with a hyphen:

    3. Demystifying 70 to 99 (The Vigesimal System)

Why does 80 translate literally to "four-twenties" (quatre-vingts)? In antiquity, the Celts and early French speakers counted by sets of twenty (base 20). Standard French preserved this structure for numbers above 69.

The 70s: Counting 60 + Teens

  • 70 : soixante-dix (60 + 10)
  • 71 : soixante-et-onze (60 + 11)
  • 72 : soixante-douze (60 + 12)
  • 75 : soixante-quinze (60 + 15)
  • 79 : soixante-dix-neuf (60 + 19)

    • Instead of a separate word for seventy, standard French continues counting upward from sixty:

    The 80s: Four Twenties

  • 80 : quatre-vingts (4 × 20). Note the plural s on vingts.
  • 81 : quatre-vingt-un (Notice: no "et", and the "s" is dropped).
  • 85 : quatre-vingt-cinq
  • 89 : quatre-vingt-neuf

    • The 90s: Four Twenties Plus Teens

  • 90 : quatre-vingt-dix ([4 × 20] + 10)
  • 91 : quatre-vingt-onze
  • 95 : quatre-vingt-quinze
  • 99 : quatre-vingt-dix-neuf

Finally, 100 is simply cent.

> Regional Tip: In Belgian and Swiss French, speakers use logical regular alternatives: septante (70) and nonante (90). In Switzerland, you will also hear huitante for 80.

4. Key Pronunciation & Liaison Rules

1. Variable Pronunciations (6, 8, 10):

  • Alone: Final consonant is audible (six [sis], dix [dis]).
  • Before consonants: Final consonant goes silent (six livres -> [si leevr]).
  • Before vowels (liaison): Changes to a [z] sound (dix enfants -> [deez-ahn-fahn]).

2. The silent "t" in vingt:

  • Alone, vingt is pronounced [vɛ̃] without the t.
  • From 21 to 29, the t wakes up: vingt-trois is pronounced [vɛ̃t-tʁwa].

By practicing the patterns in small blocks, counting from 1 to 100 in French will quickly become second nature!
