Master French Numbers: A Quick Guide to Counting and Writing in French
Learning to count in French feels intimidating at first glance, yet the payoff is immediate and practical.
Mastering the system unlocks everyday tasks like shopping, scheduling, and reading addresses without mental translation.
The Cardinal Foundation: 0-20 and Why They Matter
Zero to ten are the daily currency of conversations. zéro, un, deux, trois, quatre, cinq, six, sept, huit, neuf, dix roll off the tongue once muscle memory sets in.
Eleven to sixteen follow a unique pattern: onze, douze, treize, quatorze, quinze, seize. Each ends in -ze, making them rhyme as a group.
Seventeen to nineteen switch to a “ten-plus” logic: dix-sept, dix-huit, dix-neuf. Hearing dix-sept literally “ten-seven” cements the additive mindset early.
Memory Hooks for 0-20
Pair trois with the shape of the numeral 3 turned sideways; both mimic the letter m. Quatre sounds like “cat” with an extra r; picture four cats.
For seize, remember that 16 is the legal driving age in France, making the word unforgettable for teens.
21-69: The Tens and Units Game
From twenty onward, French counts in base-ten packets glued by hyphens. vingt et un is the lone exception at 21, inserting et to break monotony.
Twenty-two becomes vingt-deux, thirty-one trente et un, and so forth. The hyphen stays except when et appears.
Listen for liaison: the t in vingt links into the next vowel, so vingt-huit sounds like vin-tuit.
Listening Drill

70-99: The Quirky French Math
Rather than invent new words, French multiplies and adds. Seventy is soixante-dix, literally “sixty-ten”.
Seventy-one becomes soixante et onze, keeping the et tradition. Eighty flips to quatre-vingts, “four twenties”.
Eighty-one drops the final s: quatre-vingt-un. Ninety continues the math: quatre-vingt-dix, then quatre-vingt-onze up to 99.
Belgian and Swiss Variations
In Belgium, septante and nonante replace the math-heavy forms. Switzerland follows suit, sparing learners mental gymnastics.
When traveling, switch vocabulary accordingly to avoid blank stares.
Writing Rules: Hyphens, Plurals, and Silent Letters
Hyphens connect every element except after et. vingt-trois has one; trente et un has none after et.
Plural s appears only on round tens when followed by another number. quatre-vingts gains the s, but quatre-vingt-un loses it.
Silent letters trip spell-checkers: the f in neuf becomes voiced v in neuve when feminine, yet stays silent in masculine neuf.
Ordinal Numbers: Position and Agreement
Ordinals indicate rank. premier, deuxième, troisième are the first three. Note premier becomes première before a feminine noun.
After deuxième, add -ième to the cardinal root. vingt-et-unième shows the hyphen marathon continues.
Abbreviate with superscript e or ème in writing: 1er, 2e, 21e.
Practical Usage
Write au 3e étage on envelopes to specify floor three. Landlords and delivery drivers expect this format.
Large Numbers: Thousands, Millions, and Beyond
One thousand is mille, never pluralized. deux mille keeps the same form.
One million becomes un million, and the noun that follows is introduced by de: un million de personnes.
Billion is un milliard, differing from the English “billion”. Misreading contracts is costly.
Spacing Conventions
Use thin spaces every three digits: 1 000 000. Word processors auto-format, but handwriting must respect this rule.
Decimal and Currency Format
France swaps the comma and period roles. 3,14 equals 3.14 in English contexts.
Euros and cents use the comma: 12,50 €. Prices are read douze euros cinquante without et.
Handwritten checks require the amount spelled out: deux mille trois cent vingt et un euros et quarante-cinq centimes.
Phone Numbers and Postal Codes
French phone numbers are recited in pairs: 06 12 34 56 78 becomes zéro six, douze, trente-quatre, cinquante-six, soixante-dix-huit.
Postal codes stay numeric; 75008 Paris is “sept-cinq-zéro-zéro-huit”. Saying each digit avoids confusion with soixante-quinze.
Dictation Exercise
Have a friend read random ten-digit numbers; transcribe them as spoken pairs. Accuracy improves within a week.
Date and Time Expressions
The first day uses premier; the rest are cardinals. le 1er mai, le 2 mai.
Years are read as full numbers: 1999 is mille neuf cent quatre-vingt-dix-neuf.
Time past the half-hour subtracts from the next hour: 4 h 40 becomes cinq heures moins vingt.
Quick Conversion Trick
Subtract the minutes from 60 and prepend moins. Thirty-five past becomes twenty-five to the next hour.
Weights, Measures, and Everyday Quantities
Half-kilo is un demi-kilo. Quarter-liter is un quart de litre. These fractions appear on market labels.
Recipes demand precision: 250 g de farine reads deux cent cinquante grammes de farine. Saying the de after the number prevents awkward pauses.
Speed limits: 130 km/h is cent trente kilomètres-heure. Note the plural s on both kilomètres and heure.
Idiomatic Uses of Numbers
Faire les quatre cents coups means raising hell, not literally four hundred blows. Se mettre sur son trente et un translates to dressing to the nines.
The expression le 36e dessous refers to the absolute worst place, derived from historic Parisian basement numbering.
Learning such phrases anchors numbers in memory through vivid imagery.
Audio Mimicry and Shadowing Techniques
Choose a French news podcast with clear articulation. Pause after each number and repeat aloud within one second.
Focus on nasal vowels in vingt, cinq, un; exaggerate the nasality to match native resonance.
Record yourself counting from 70-99; play back and compare against native clips. Mispronounced liaison stands out immediately.
Common Pitfalls and How to Dodge Them
Misplacing hyphens creates spelling errors. Always write vingt-cinq, never vingt cinq in formal contexts.
Forgetting silent letters alters meaning. Quatre and quatre-vingt differ by context alone.
Over-anglicizing cent as “sent” confuses listeners. Aim for a crisp sahn without the trailing t.
Progressive Practice Schedule
Day 1: master 0-20 flashcards with audio. Day 2: add 21-69 in tens. Day 3: tackle 70-99 with math visualization.
Weekend: integrate dates and times. Write out tomorrow’s schedule entirely in French.
By day 10, conduct a mock market transaction aloud, negotiating prices from 1 € to 99 €.
