I love Nahuatl!

The easy mistake most people make is throwing in hard K sounds. Those are usually written as Cs and Qs. X is "sh" and the ch is soft. "tl" has no actual English equivalent, but it's kind of like a welsh double L, only starting with the tongue against the roof of the mouth.
If there's one thing I want from 5e it's more Nahuatl.
In fact, maybe early next year I'll make a "Mayincatec" setting featuring more Nahuatl, Yucatan Maya, and Quechua than you can shake a conquistador at.
Because Tékumel was not enough, my friends.
