1.3 The “Irregular” Teens: 70–99

French uses a vigesimal (base-20) logic for 70–99:

  • 70 = soixante-dix (60 + 10)

  • 71 = soixante-et-onze (60 and 11)

  • 79 = soixante-dix-neuf (60 + 19)

  • 80 = quatre-vingts (4 × 20)

  • 81 = quatre-vingt-un (4×20 + 1)

  • 89 = quatre-vingt-neuf

  • 90 = quatre-vingt-dix (4×20 + 10)

  • 99 = quatre-vingt-dix-neuf

Mnemonic: Think of 80 as “four twenties,” and build 70/90 by adding ten to 60 or 80 respectively.

1.4 Hundreds, Thousands, and Beyond

  • 100 – cent (pl. cents when alone or round)

  • 200 – deux cents

  • 201 – deux cent un (no “s” on cent when followed by another number)

  • 1,000 – mille (never pluralized)

  • 2,000 – deux mille

For larger numbers, French follows the international system:

  • 1,000,000 – un million

  • 1,000,000,000 – un milliard

2. Ordinal Numbers: First, Second, Third…

French ordinals are formed by adding “-ième” to the cardinal, with a few exceptions:

EnglishCardinalOrdinalNotes

2nddeuxdeuxième 
3rdtroistroisième 
4thquatrequatrième 
5thcinqcinquième 
9thneufneuvième“f” → “v” before “ième”
20thvingtvingtième 
100thcentcentième 

Usage: Ordinals are essential for dates (le 1er mai, le 2 septembre), floors in a building (le troisième étage), and ranking (la quatrième place).


3. Practical Usage Tips

3.1 Telling Time

  • Il est deux heures et quart. (It’s 2:15.)

  • Il est trois heures moins dix. (It’s 2:50 / ten minutes to 3.)

Use “et quart” (+15), “et demie” (+30), and “moins” (minus) for minutes before the hour.

3.2 Dates

French dates follow day-month-year:

  • le 14 juillet 1789 (Bastille Day)

  • Months are lowercase: janvier, février, etc.

  • For the first day: le 1er mai (May 1st)

3.3 Prices and Shopping

  • Combien ça coûte ? (How much does it cost?)

  • C’est vingt-neuf euros cinquante. (€29.50)

  • Decimals use a comma (29,50 €).

3.4 Phone Numbers

French phone numbers are grouped in pairs:

  • 01 23 45 67 89

  • The first two digits often indicate the region (01 = Île-de-France).


4. Pronunciation and Mnemonics

  • Nasal vowels (e.g., “un,” “vingt”) are typical in French. Practice by lightly closing the back of your throat.

  • Liaison: In “vingt et un,” the final “t” of “vingt” is pronounced because of the following vowel sound.

  • Memory trick for 80: Picture four “vingt” coins stacking into the shape of “80.”
