English has also absorbed words of Nahuatl origin, including avocado, chayote, chili, chipotle, chocolate, atlatl, coyote, peyote, axolotl and tomato. These words have since been adopted into dozens of languages around the world.[15][16] The names of several countries, Mexico, Guatemala, and Nicaragua, derive from Nahuatl.
