Understanding French Cardinal Numbers: "Cent, Mille, Million"

This lesson introduces key French cardinal numbers that express precise quantities. You will learn how to say and write the numbers 100 (cent), 1,000 (mille), 1,000,000 (million), and beyond. These basic numbers form an essential foundation for counting, shopping, telling dates, and much more in French.

Key Vocabulary and Usage

  • Cent means one hundred. Note that it takes an "s" in the plural form when standing alone (e.g., deux cents for 200) but loses the "s" when followed by another number (e.g., deux cent un for 201).
  • Mille means one thousand and is always invariable — it never takes an "s," regardless of quantity, unlike English where "thousands" is pluralized.
  • Million and milliard (billion) behave like regular nouns that take an "s" in the plural: deux millions (two millions) and deux milliards (two billion).

Practical Examples

You will see examples such as "J'ai compté deux cents pommes" (I counted two hundred apples) and "Nous avons mille euros" (We have one thousand euros). These examples demonstrate how cardinal numbers are used naturally in context.

Differences Between English and French Number Usage

One notable difference is the invariable nature of mille compared to English pluralization of "thousand." Also, while English uses "million" uniformly, French treats million and milliard as nouns that must agree in number. Additionally, the pluralization rules for cent are specific and must be carefully observed to ensure grammatical accuracy.

Useful Phrases

  • cent – one hundred
  • deux cents – two hundred
  • mille – one thousand
  • un million – one million
  • deux millions – two million
