I have said nothing of the proper names in this paragraph. They are remarkable for the fact that three out of the four are unquestionably Nahuatl or Aztec, and hence they have given occasion for considerable theorizing in favor of the "Toltec" origin of the Maya civilization, and also of the Nahuatl descent of the princely family of the Tutulxiu. Their name is the only one in the paragraph with a distinctively Maya physiognomy. It is a compound of _xiu_, the generic term for herb or plant, and _tutul_, a reduplicated form of _tul_, an abundance, an excess, as in the verb _tutulancil_, to overflow, etc. (_Diccionario de Ticul_, MS.). It would appear therefore to be a local name, and to signify a place where there was an abundance of herbage. The surname is Xiu only, and as such is still in use in Yucatan. But it may also be claimed that even this is a Nahuatl name; for also in that tongue _xiuitl_ means a plant, as well as a turquoise, a comet, a year, and in composition a greenish or bluish color; while _tototl_ is a bird or fowl. The Maya _xiu_ and the Nahuatl _xiuitl_ (in which _itl_ is a termination lost in composition) are undoubtedly the same word. Which nation borrowed it from the other? It is certainly a loan-word, for these two languages have no common origin, while, as we might expect from neighbors, each does have a number of loan-words from the other. I answer that the Maya _xiu_ is unquestionably a loan from the Nahuatl, and my reason for the opinion is that while in Maya the root _xiu_ is sterile and has no relations to other words (unless perhaps to _xiitil_, to open like a flower, to brood as a bird, to augment, to grow), in Nahuatl it is a very fertile root, and nearly thirty compounds of it can be found in the dictionaries (See Molina, _Vocabulario de la Lengua Mexicana_, fol. 159, verso). But the composition of the name follows the Maya and not the Nahuatl analogy.
