The Story

Nahuatl is the language of the Aztecs — or, as they called themselves, the Mexica. But the Nahuatl-speaking peoples arrived in central Mexico long before the Aztec Empire. The Uto-Aztecan language family originated in the deserts of what is now the southwestern United States, and Nahuatl speakers migrated southward over centuries, reaching the Valley of Mexico around 600 CE. The great city of Teotihuacan may have had Nahuatl speakers; the Toltec civilization certainly did.

When the Aztec Empire rose to dominance in the 15th century, Nahuatl became the lingua franca of Mesoamerica — spoken from the deserts of northern Mexico to the jungles of Central America. The Aztec capital Tenochtitlan (on the site of modern Mexico City) was one of the largest cities in the world, with 200,000–300,000 inhabitants. Nahuatl was the language of administration, poetry, philosophy, and a sophisticated intellectual tradition that the Spanish found astonishing.

The Spanish conquest of 1521 devastated the Aztec world, but it did not kill Nahuatl. Spanish missionaries actually promoted the language, using it to convert indigenous peoples across Mexico. They created grammars, dictionaries, and vast archives of Nahuatl literature. For decades, Nahuatl was the administrative language of colonial Mexico alongside Spanish. Thousands of Nahuatl words entered Spanish, and through Spanish, they entered every European language.

Today, 1.7 million people still speak Nahuatl in Mexico — making it the most widely spoken indigenous language in North America. But its global legacy is in the words: chocolate (xocolātl), tomato (tomatl), avocado (āhuacatl), coyote (coyōtl), chipotle (chīlpoctli), guacamole (āhuacamōlli). These words are so deeply integrated into English that most speakers have no idea they come from an indigenous American language.
