Latin Numbers
Latin numbers are used to express quantity, count objects, and form the foundation for many modern number systems in European languages.
Latin was the language of ancient Rome and has influenced many modern languages including Spanish, French, Italian, Portuguese, and Romanian. Learning Latin numbers can help you recognize patterns in these languages and understand many historical texts.
Latin numbers are also closely related to Roman numerals, which are still used today in books, clocks, outlines, and formal numbering systems.
This page explains how Latin numbers work and provides links to charts and practice tools to help you learn and practice.
