91 to 99 in French

Famously the hardest range in French to count out loud. Every number is quatre-vingt + a teen. Belgium and Switzerland skip the puzzle with nonante.

The two-step memory hack

  1. Start with quatre-vingt.
  2. Add the teen (11 = onze, 12 = douze, 13 = treize, 14 = quatorze, 15 = quinze, 16 = seize, 17 = dix-sept, 18 = dix-huit, 19 = dix-neuf).

The hyphens hold the morphemes together. No s on vingt because units follow. No et connector ever.

Frequently asked

Why is 91 quatre-vingt-onze and not quatre-vingt-dix-un?

Because French treats 90 to 99 as the teens of the 80-base block. 90 = 80 + 10 = quatre-vingt-dix. 91 = 80 + 11 = quatre-vingt-onze. The teen words (onze, douze ... dix-neuf) substitute for what would otherwise be dix-un, dix-deux. The whole second half of the vigesimal cycle reuses the 11 to 19 vocabulary.

What is 97 in French?

Quatre-vingt-dix-sept. Breaks down as 4 x 20 + 17. IPA /katʁ.vɛ̃.dis.sɛt/. Belgium and Switzerland: nonante-sept.

What is the trick to remembering 91 to 99?

Two-step it. Step one: every number is quatre-vingt plus a teen. Step two: pick the right teen (onze 11, douze 12, treize 13, quatorze 14, quinze 15, seize 16, dix-sept 17, dix-huit 18, dix-neuf 19). If you can recite the teens you can build any number from 91 to 99 by prefixing quatre-vingt-.

Do Belgians say quatre-vingt-onze?

No. Belgian French uses nonante-un (91), nonante-deux (92), all the way to nonante-neuf (99). Same in Swiss French (nonante in all cantons). If you hear quatre-vingt-onze you are listening to standard French from France or Quebec.
