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

This lesson focuses on French cardinal numbers, specifically the expressions for hundred (cent), thousand (mille), and million (million). These numbers represent exact quantities and are essential for everyday counting, telling prices, dates, and much more.

Key Numbers Covered

  • 100Cent
  • 200Deux cents
  • 201Deux cent un
  • 1 000Mille
  • 2 000Deux mille
  • 1 000 000Un million
  • 2 000 000Deux millions
  • 1 000 000 000Un milliard
  • 2 000 000 000Deux milliards

Important Grammar Highlights

  • Pluralization of "cent": The word cent takes an "s" in the plural only when it is not followed by another number. For example, deux cents (200) but deux cent un (201) without the "s".
  • Invariable "mille": The term mille (thousand) never changes and never takes an "s" in its plural form. For example, mille (1,000) and deux mille (2,000) both remain unchanged.
  • Pluralization of "million": The word million takes an "s" in the plural: deux millions (2 million).

Useful Expressions and Notes

French cardinal numbers combine with other numbers and nouns in specific ways. For example:

  • J'ai compté deux cents pommes dans le panier. (I counted two hundred apples in the basket.)
  • Nous avons mille euros pour acheter les matériaux. (We have a thousand euros to buy the materials.)
  • Elle a gagné un million d'euros à la loterie. (She won one million euros in the lottery.)

Comparing French and English

Unlike English, where numbers like "hundreds," "thousands," and "millions" are always pluralized with an "s," French follows specific rules depending on the number and what follows:

  • Cent adds an "s" only when it stands alone or ends the number, but not before another number.
  • Mille is always invariable and never takes an "s," even when referring to multiple thousands.
  • Million behaves similarly to English and adds an "s" in the plural.

Familiarity with these rules will help you construct numbers correctly and sound natural in French.

Quick Tip

Remember: cent (hundred) vs. cents (hundreds), mille (thousand) always without "s", and millions (millions) with "s" when plural.
