ahuatl (Mdz21v)
This element has been carved from the compound glyph for the place name, Ahuatepec. It shows an oak tree with three branches, each with green foliage at the ends. Emerging from the green foliage we see turquoise-colored water (atl). So, this is an element from a compound glyph, but it still has two elements, with a downward reading order. This recurs across other examples of the sign for ahuatl, oak tree.

This visual of water (atl) coming out of the branches of the tree is a phonetic clue that we are not seeing just any tree (cuahuitl), but a tree beginning with the sound "a." Wiktionary has an entry for ahuatl. Some Nahuas today also have the last name Ahuatl.
