2️⃣ Cardinal Numbers – General Rules

Cardinal numbers (nombres cardinaux) are used to count and indicate quantities. With the exception of un and une, they are generally invariable in gender.

📌 Usage Notes

  • 1️⃣ Units (0–9) – These are the basic building blocks of all numbers. Examples: • trois → three • sept → seven • neuf → nine
  • 2️⃣ Tens (10, 20, 30…) – Tens combine with units using a hyphen, and et is used before “un” (except for 81 and 91 in standard French). Examples: • vingt-trois → twenty-three • trente et un → thirty-one • soixante-dix → seventy • quatre-vingt-dix-neuf → ninety-nine
  • 3️⃣ Hundreds – Formed by adding the number before cent. • Cent takes an “s” when multiplied and not followed by another number. Examples: • deux cents → two hundred • trois cent dix → three hundred ten • quatre cent soixante → four hundred sixty • cinq cent quatre-vingt-dix-sept → five hundred ninety-seven
  • 4️⃣ Thousands – The word mille is invariable (no “s” in plural). Examples: • deux mille → two thousand • dix mille → ten thousand • soixante-quinze mille → seventy-five thousand • deux mille vingt-cinq → two thousand twenty-five • trois mille quinze → three thousand fifteen
  • 5️⃣ Millions – Million takes an “s” in the plural. Examples: • un million → one million • cinq millions → five million • dix-huit millions deux cent mille → eighteen million two hundred thousand • soixante millions trois cent vingt et un → sixty million three hundred twenty-one
  • 6️⃣ Billions – Milliard (billion) also takes an “s” in the plural. Examples: • un milliard → one billion • trois milliards cinquante → three billion fifty • vingt-cinq milliards cent mille → twenty-five billion one hundred thousand • quarante milliards deux cent vingt-trois mille cinq cents → forty billion two hundred twenty-three thousand five hundred

3️⃣ Cardinal Numbers – Key Spelling Rules

French cardinal numbers follow specific spelling and agreement rules. Understanding these rules will help you avoid common mistakes when writing or speaking large numbers.

📌 Trait d’union dans les nombres

📌 Particularités Belgique & Suisse

✅ Remember: The hyphen rule from the 1990 reform is now widely taught in schools, but older texts may not always use it. When in doubt, use a hyphen between all parts of a number except before "et un".

4️⃣ Ordinal Numbers – General Rules

Ordinal numbers indicate the position or rank of something in a sequence (first, second, third, etc.). In French, they agree in gender and number with the noun they modify.

ℹ️ Note on Suffixes

✅ Unlike in English, ordinal numbers in French always agree in gender and number with the noun they describe. For example: FR: la troisième fois → EN: the third time FR: les quatrièmes places → EN: the fourth places

5️⃣ Irregular Ordinals & Special Cases

While most ordinal numbers in French follow regular rules, there are several exceptions and special cases worth remembering.

📌 Premier / Première

📌 Second / Seconde vs. Deuxième

📌 Dernier / Dernière

📌 Centième, Millième, and Beyond

📌 Large Ordinals

✅ Remember: All these forms agree in gender and number with the noun they qualify. FR: la millième personne → EN: the thousandth person (feminine)

6️⃣ Usage of Ordinal Numbers in Dates and Ranking

Ordinal numbers in French are commonly used in two main contexts: to express dates and to indicate ranking or position in a competition or sequence.

📅 Ordinals in Dates

⚠️ Note: In spoken French, people often use cardinals for all dates, but in writing, only the first day uses an ordinal (1er / 1re).
