What are Aztec words that have z in them?

It's important to note that the Aztec language, Nahuatl, did not have a letter 'z' in its alphabet. The letter 'z' was introduced by Spanish colonizers and wasn't part of the original Nahuatl writing system.

While the Aztec language did have sounds that resemble 'z' in some contexts, they were represented by other letters or combinations of letters.

Therefore, you won't find any Aztec words written with the letter 'z'.

If you're interested in exploring the sounds of Nahuatl, it's best to consult resources that use the original Nahuatl orthography or phonetics.
