His Nahuatl names () mean "Runs Swiftly with a Shield" and "Rising Eagle", respectively, and he claimed descent from the lords of Tenango-Amecameca-Chalco.

Classical Nahuatl, also known simply as Aztec or Codical Nahuatl (if it refers to the variants employed in the Mesoamerican Codices through the medium of Aztec Hieroglyphs) and Colonial Nahuatl (if written in Post-conquest documents in the Latin Alphabet), is a set of variants of Nahuatl spoken in the Valley of Mexico and central Mexico as a lingua franca at the time of the 16th-century Spanish conquest of the Aztec Empire. During the subsequent centuries, it was largely displaced by Spanish and evolved into some of the modern Nahuan languages in use (other modern dialects descend more directly from other 16th-century variants). Although classified as an extinct language, Classical Nahuatl has survived through a multitude of written sources transcribed by Nahua peoples and Spaniards in the Latin script.
