Numbers in French follow a unique vigesimal (base-20) system combined with decimal elements, making it distinct among European languages. Spoken by about 80 million native speakers mainly in France, Belgium, Switzerland, and Canada, French's counting system reflects its Celtic heritage. The language's structure influences how compound numbers are formed, especially from sixty-one onwards. Understanding the numbers in French reveals a fascinating blend of decimal and vigesimal patterns, with special rules for numbers like 71 (soixante et onze) and 80 (quatre-vingts). This system makes French counting both intriguing and complex for learners and linguists alike.

Mixed vigesimal-decimal system
Vigesimal (base-20) combined with decimal (base-10)

French counting primarily uses a vigesimal system from sixty-one onward, where 70 is 'soixante-dix' (60+10), and 80 is 'quatre-vingts' (4*20). For example, 6 is 'six', 7 is 'sept', and 8 is 'huit'. Numbers 17-19 are formed by combining 'dix' (10) with units: dix-sept (17), dix-huit (18), dix-neuf (19). Tens like 30 ('trente') and 40 ('quarante') are straightforward, but from 60, the pattern shifts: 60 is 'soixante', 70 is 'soixante-dix' (60+10), and 90 is 'quatre-vingt-dix' (4*20+10). Compound numbers like 42 are 'quarante-deux' (40+2), and 78 is 'quatre-vingt-dix-huit' (80+10+8). The hyphen joins tens and units, with 'et' used for numbers like 21 ('vingt et un').
