The other day I stumbled across the meaning of the word "Mexico."
It comes from the Nahuatl language. The Nahuatl culture is also known as "Aztec." One of the foremost modern Nahuatl translators said that "Mexico" comes from 2 words in Nahuatl: "metatli" (moon) and "xictli" (navel). Put them together, and you get "navel of the moon."
There is a little disagreement over the first section of the word, and...instead of "moon" it may be "maguey plant" (from which tequila are mescal are made). So, depending on how you look at it I'm either living in the Navel of the Moon (nice and poetic) or the navel of the maguey cactus (sort of pre-alcoholic). I prefer the Moon.
