Why is the French number system based on twenties after the number sixty?

The French number system is famously unique, especially after sixty, where it starts using a base-twenty (vigesimal) counting method. If you have ever wondered why seventy is “soixante-dix” (sixty-ten), eighty is “quatre-vingts” (four twenties), and ninety is “quatre-vingt-dix” (four twenties ten), you are not alone! This linguistic curiosity often intrigues French learners and sometimes confuses them. In this article, we will explore the fascinating history and logic behind the French numbers, and how understanding this can help you master French more effectively with resources like Talkpal AI.

The Structure of French Numbers: An Overview

French numbers from one to sixty follow a predictable pattern based on the decimal (base-10) system, much like English. However, once you reach seventy, things start to change. Instead of a direct word for seventy, French uses “soixante-dix” (sixty-ten), for eighty it’s “quatre-vingts” (four twenties), and for ninety it’s “quatre-vingt-dix” (four twenties ten). This mix of decimal and vigesimal (base-20) logic is a linguistic feature that sets French apart from many other European languages.

Historical Origins of the Vigesimal System

To understand why French uses a base-twenty system after sixty, we need to look back at its history. The vigesimal system has ancient roots, likely stemming from the Celtic and possibly even the Basque languages spoken in the region before Latin and modern French took hold. Many ancient societies, including the Celts, used base-20 for counting, possibly related to counting both fingers and toes for totals of twenty.

During the Middle Ages, Old French was influenced by these pre-Roman languages, and the vigesimal system became ingrained in certain numbers. While Latin, the language of the Romans, used a pure decimal system, the local traditions persisted and eventually merged into the French language we know today.

Why After Sixty?

Sixty marks a turning point in French numerals because of historical counting methods and linguistic evolution. In some regions, people counted in twenties for larger numbers. For example, instead of saying seventy, they would say “sixty-ten,” and for eighty, “four twenties.” Over time, this system became standardized in French, especially in the north of France and in Paris, the cultural and administrative center. This is why modern standard French, as used in France, follows this vigesimal pattern after sixty.

Interestingly, in some French-speaking regions like Belgium and Switzerland, a more decimal approach is still used. For example, in Belgium, seventy is “septante” and ninety is “nonante,” reflecting a simpler decimal structure. However, in France and most French-speaking regions, the traditional system prevails.

The Vigesimal System in Practice

Here is how the French numbers are constructed after sixty:

This system may seem complicated at first, but with practice and exposure, such as through interactive platforms like Talkpal, learners quickly adapt.
