格雷羅那瓦特爾語

Guerrero Nahuatl is a Central Nahuan language of the Uto-Aztecan family, spoken by around 150,000 people in the Sierra Norte/La Montaña region of Guerrero state, Mexico. Linguistically, it is one of the major Modern Nahuatl varieties alongside the Huasteca varieties (nch/nhw/nhe), with distinct phonological features such as the "saltillo" glottal stop in places where Classical Nahuatl had a /h/ or /ʔ/. Guerrero Nahuatl is part of the broader Modern Nahuatl dialect continuum descended from the Postclassic Aztec lingua franca, but with significant divergence from the Central Mexican varieties. The Guerrero region was a major Aztec frontier zone where the Triple Alliance encountered the Mixtec, Tlapanec, and Amuzgo peoples, contributing to lexical and phonological diversity in modern Guerrero Nahuatl.
