French numbers, and why 97 is “four-twenty-seventeen”

French numbers are regular from 0 to 69. Then they switch to counting in twenties, a habit inherited from older languages of the region: 70 is “sixty-ten”, 80 is “four-twenties”, 90 is “four-twenty-ten”. Once you see the arithmetic, every number to a million follows.

97 = 4 × 20 + 17 20 20 20 20 + 17 = 97 quatre-vingtfour twenties dix-septten-seven kah-truh-va(n)-dee-SET
French speakers do not do the sum when they speak, any more than you think “forty” is “four tens”. Learn 70, 80 and 90 as words and the rest is adding on.

Short answer: learn 0–16 by heart; 17–19 are “ten-seven” to “ten-nine”. Tens to 60 work like English. 70 = soixante-dix, 80 = quatre-vingts, 90 = quatre-vingt-dix. 100 = cent, 1,000 = mille. French writes 1 000,50 where English writes 1,000.50.

0 to 20

These are the building blocks. From 17, French builds by adding: dix-sept is literally “ten-seven”. Press any number to hear it.

21 to 69: tens plus units

Say the ten, then the unit, joined by a hyphen: vingt-deux (22), trente-cinq (35). The one exception is 1: each ten adds et un, “and one”, without a hyphen: vingt et un (21), quarante et un (41).

TenWord… and one… and two
20 vingt et un (21) vingt-deux (22)
30 trente et un (31) trente-deux (32)
40 quarante et un (41) quarante-deux (42)
50 cinquante et un (51) cinquante-deux (52)
60 soixante et un (61) soixante-deux (62)

70 to 99: counting in twenties

Above 69, France counts on from sixty and then from eighty, so the units run from 10 to 19. Choose a number to see how it is built.

From 70, France keeps counting past 60 and then in twenties, a trace of an older counting system. Belgium and Switzerland use septante and nonante instead; see regional French.

71 keeps “et”soixante et onze, sixty and eleven. But 81 and 91 drop it: quatre-vingt-un, quatre-vingt-onze.
80 has an s, 81 does notquatre-vingts ends in s because it is “four twenties”. The s goes as soon as another number follows: quatre-vingt-deux.
Belgium and Switzerland70 is septante, 90 is nonante, and in much of Switzerland 80 is huitante. Everyone in France understands them. Where each is used is on the French hub.

100 and above

Cent (100) and mille (1,000) never take un in front: “hundred”, not “one hundred”. Large numbers are grouped in threes with a space, and the decimal point is a comma.

Numbers that change sound

Several numbers end in a consonant that behaves like other silent letters: said alone, dropped before a consonant, linked before a vowel. This matters most for prices and times.

5 · cinq
6 · six
8 · huit
10 · dix

Prices, phone numbers, ages and dates

Four places you will hear numbers every day. Every word has its English meaning underneath.

A price
Çathatfaitmakesquatre-vingt-dix-neuf99euroseuroscinquante.50
sah feh kah-truh-va(n)-deez-NUF uh-ROH sa(n)-KAH(N)T “That’s €99.50.” Why: Ça fait, “that makes”, is how shops give the total. Cents follow euros without a word for “and”. Written 99,50 €.

First, second, third: ordinal numbers

An ordinal number gives a position in a row: first, second, tenth. French adds -ième to the number, dropping a final e first: quatre → quatrième. Only “first” is different: premier, or première with a feminine noun. Ordinals are written 1er, 2e, 3e. Floors, arrondissements of Paris and centuries use them; dates do not, except the first of the month.
