French Numbers 70 to 99
The Complete Guide with Colour-Coded Breakdown

Updated 17 April 2026

Every French learner hits a wall at 69. The reason is that French switches from a base-10 counting system to a base-20 (vigesimal) one at 70. While Spanish has setenta (70), ochenta (80), noventa (90), French uses soixante-dix (sixty-ten), quatre-vingts (four-twenties), and quatre-vingt-dix (four-twenties-ten). You are not just reading a word - you are doing arithmetic.

This page covers the complete 70-99 range with audio, colour-coded breakdown showing the arithmetic, common mistakes, memory tricks, and a typed-answer drill. Belgium and Switzerland forms (septante, huitante, nonante) are shown alongside for comparison.

The Three Patterns

70-79

soixante (60) + dix/onze/douze... up to dix-neuf

70 = soixante-dix

71 = soixante-et-onze (note: -et- before onze)

75 = soixante-quinze

79 = soixante-dix-neuf

80-89

quatre-vingt (4x20) + un/deux... up to neuf

80 = quatre-vingts (with s alone)

81 = quatre-vingt-un (no s, no et)

85 = quatre-vingt-cinq

89 = quatre-vingt-neuf

90-99

quatre-vingt (4x20) + dix/onze... up to dix-neuf

90 = quatre-vingt-dix

91 = quatre-vingt-onze

95 = quatre-vingt-quinze

99 = quatre-vingt-dix-neuf

Common Mistakes

Wrong: Writing "quatre-vingt-et-un" for 81

Correct: quatre-vingt-un

The -et- connector is used after soixante (71 = soixante-et-onze) but NOT after quatre-vingt. 81 is quatre-vingt-un with no et.

Wrong: Writing "quatre-vingts-deux" for 82

Correct: quatre-vingt-deux

The s on quatre-vingts disappears as soon as any number follows. Only 80 standing alone keeps the s.

Wrong: Using septante in France

Correct: soixante-dix

Septante is the Belgian/Swiss form and is not used in France. Using it in Paris or Quebec will mark you as foreign, though people will understand.

Wrong: Writing "soixante-dix-et-un" for 71

Correct: soixante-et-onze

71 is not soixante-dix plus un. It is soixante (60) plus onze (11), making soixante-et-onze. The et goes before onze, not after dix.

Memory Tricks for 70-99

The key insight is to stop thinking of 70-99 as standalone words and start thinking of them as arithmetic. When you hear "quatre-vingt-dix-sept", do not try to memorise it as a 25-character word. Instead, think: "four-twenty = 80, plus seventeen = 97". The structure becomes transparent once you stop fighting it.

For the 70s: they are all soixante (60) plus the corresponding teen (10-19). You already know dix, onze, douze... up to dix-neuf. Just put soixante- in front: soixante-dix, soixante-onze... soixante-dix-neuf.

For 80-99: treat quatre-vingt as a single token meaning "the 80s". Then add the unit (1-9 for 81-89) or the teen (10-19 for 90-99). Practise hearing the "quatre-vingt" at the start and immediately thinking "80s".

Drill the 30 numbers below until they feel automatic. Research on language acquisition suggests that 70-99 takes about 50 successful recall repetitions to become automatic. The drill widget below tracks your progress.

Why Does French Count Like This?

The Celtic tribes who inhabited Gaul before Roman conquest counted in groups of twenty. When Latin arrived and replaced most Celtic vocabulary, the base-20 counting pattern survived in the 70-99 range. French is not unique in this - Welsh, Danish, and Basque also have vigesimal remnants - but it is unusual for a major modern language to retain them so prominently.

FAQ

How do you say 70 in French?

Soixante-dix (literally "sixty-ten"). It is pronounced approximately swah-sont-DEES. Belgium and Switzerland use septante (sep-TANT), which is much more logical but not used in France or Quebec.

How do you say 80 in French?

Quatre-vingts (literally "four-twenties", i.e. 4 x 20 = 80). Written with an s when it ends the number (quatre-vingts) but without s when another number follows (quatre-vingt-un, quatre-vingt-deux). Belgium uses the same form as France for 80.

How do you say 90 in French?

Quatre-vingt-dix (four-twenties-ten, 4 x 20 + 10 = 90). Belgium and Switzerland use nonante. Note: no s on quatre-vingt because dix follows.

Why is 71 "soixante-et-onze" but 81 is "quatre-vingt-un"?

The -et- connector is used for 71 (soixante-et-onze) because 71 = 60 + 11, and onze begins with a vowel requiring the connecting et. But 81 = quatre-vingt + un, and the base is a multiplication (quatre-vingt), not a simple addition from a round ten. The pattern: 21, 31, 41, 51, 61, 71 use -et-un or -et-onze. But 81 does not.

Why does French count in twenties above 69?

The Gauls (Celtic tribes in pre-Roman France) used a vigesimal (base-20) counting system. When Latin replaced Celtic vocabulary, the base-20 pattern survived in the 70-99 range. Belgium and Switzerland did not adopt France's 19th-century language standardisation, which retained the vigesimal forms, so they kept the simpler septante, huitante, nonante.

What is 97 in French?

Quatre-vingt-dix-sept. This breaks down as: quatre (4) + vingt (20) + dix (10) + sept (7) = 97. IPA: /katʁ.vɛ̃.dis.sɛt/. In Belgium and Switzerland: nonante-sept.

Is it "quatre-vingts euros" or "quatre-vingt euros"?

Quatre-vingts euros - with the s. The s appears when quatre-vingts is followed by a noun (euros, personnes, etc.) rather than another number. When a number follows, the s disappears: quatre-vingt-un, quatre-vingt-deux. This is the only exception to the "s drops before following numbers" rule.
