"he goes shining"
The name Tonatiuh is commonly a male name from the "Nahuatl" origin that means "he goes shining".
Tonatiuh is a Nahuatl name. Sixteenth-century Nahuatl texts compiled by Bernardino de Sahagun record tonatiuh as the word for the sun, and also as the name of the sun deity. Nahuatl dictionaries derive it from the verb tona, to shine or give off heat, with a directional suffix, giving a sense along the lines of "he goes shining" or "the sun."
The pronunciation of Tonatiuh is toh-nah-TEE-oo.
