Understanding French Numbers: Grammar Rules You Need to Know

Learning French numbers can be a challenge, especially when faced with their unique counting system. Whether you're a beginner or brushing up your skills, mastering French numbers is essential for daily conversations, travel, or even conducting business in French-speaking regions. In this article, we’ll break down the essential grammar rules and provide tips to help you confidently understand and use French numbers.

1. The Basics of French Numbers: 0 to 20

The foundation of French numbers starts with 0 to 20. These numbers are essential because they form the building blocks for larger numbers. Here’s a quick overview:

  • 0: zéro

  • 1: un

  • 2: deux

  • 3: trois

  • 4: quatre

  • 5: cinq

  • 6: six

  • 7: sept

  • 8: huit

  • 9: neuf

  • 10: dix

  • 11: onze

  • 12: douze

  • 13: treize

  • 14: quatorze

  • 15: quinze

  • 16: seize

  • 17: dix-sept

  • 18: dix-huit

  • 19: dix-neuf

  • 20: vingt

2. Counting Beyond 20: Rules to Remember

21, 31, 41, etc.: The Insertion of "et"

For numbers like 21, 31, 41, and so on, the word "et" (meaning "and") is inserted:

  • 21: vingt et un

  • 31: trente et un

However, this rule applies only to numbers ending in 1. For other numbers, the conjunction "et" is omitted:

  • 22: vingt-deux

  • 32: trente-deux

Numbers 70-99: A Unique Pattern

French numbers from 70 to 99 can seem tricky due to their reliance on addition and multiplication:

  • 70-79: Start with "soixante" (60) and add 10 to 19:

    • 70: soixante-dix (60 + 10)

    • 71: soixante-onze (60 + 11)

  • 80-99: Begin with "quatre-vingts" (literally "four twenties") and add:

    • 80: quatre-vingts

    • 81: quatre-vingt-un

    • 91: quatre-vingt-onze

3. Plurals with French Numbers

The plural rule applies to "vingt" and "cent" but only under certain conditions:

  • Vingt and cent take an "s" when multiplied but not followed by another number:

    • 80: quatre-vingts (with an "s")

    • 81: quatre-vingt-un (no "s")

  • Mille (thousand) never takes an "s," regardless of context:

    • 2,000: deux mille

4. Ordinal Numbers

Ordinal numbers (first, second, third, etc.) are used to indicate order. In French, they are formed by adding -ième to the cardinal number, with a few exceptions:

  • 1st: premier/première

  • 2nd: deuxième (or second/seconde)

  • 3rd: troisième

For numbers ending in -e, such as quatre (4), the final -e is dropped before adding -ième:

  • 4th: quatrième

5. Common Uses of Numbers in French

Telling Time

French uses the 24-hour clock for formal settings, but the 12-hour clock is common in casual conversations. Don’t forget to use "heure(s)" after the hour:

  • 3:00: trois heures

  • 15:00: quinze heures

Dates

French dates follow the day-month-year format, and ordinal numbers are only used for the first day of the month:

  • 1st of January: le premier janvier

  • 5th of March: le 5 mars

Prices and Currency

When stating prices, the currency symbol follows the number:

  • €10: dix euros

  • €4.50: quatre euros cinquante

6. Tips to Master French Numbers

  1. Practice Daily: Incorporate numbers into your routine by reading prices, dates, or times aloud.

  2. Use Flashcards: Create flashcards to test yourself on tricky numbers, especially those between 70 and 99.

  3. Listen and Repeat: Watch French videos or listen to audio that includes numbers to familiarize yourself with their pronunciation.

    Conclusion

Understanding French numbers requires a mix of memorization and practice, but with the right approach, you'll master them in no time. Focus on the rules outlined here, and don’t hesitate to immerse yourself in real-world scenarios where numbers are used.
