Nahuatl

Where it’s spoken

Nahuatl is spoken across central and southern Mexico, with major dialect clusters in Puebla, Veracruz, Hidalgo, San Luis Potosí, Guerrero, and Morelos. About 1.7 million speak it, making it the most widely spoken Indigenous language of Mexico. It is one of 68 officially recognized national languages of Mexico under the 2003 General Law of Linguistic Rights.

What it sounds like

Nahuatl has four vowels (a, e, i, o) with phonemic length and 15–16 consonants depending on variety. Distinctive features include the lateral affricate tl (where Nahuatl gets its iconic sound and its name) and aspirated stops in some dialects. The language is non-tonal. Words can be very long because of agglutination.

How it’s written

Nahuatl was written in pre-Columbian pictographic codices before the Spanish conquest. Spanish missionaries adapted the Latin alphabet in the 16th century, producing extensive Classical Nahuatl literature. Modern orthographies are still being negotiated — variants debate how to mark glottal stops, vowel length, and the spelling of tl.

History

Classical Nahuatl (Mexica) was the imperial language of the Aztec Triple Alliance. Bernardino de Sahagún’s 16th-century Florentine Codex preserved much pre-Columbian knowledge in Nahuatl with parallel Spanish. Modern Mexico has revitalization programs through the INALI.
