 Nahuatl "tlaxcalli" is derived from the verb "(i)xca" "to bake" with the help of the prefix "tla"- and two common suffixes -"l"- and -"li" ( As such, this wheat flour flatbread tortilla is not to be confused with the Spanish omelette or any other egg based one.The corn tortilla, with many variants, has been a staple food in North American and Mesoamerican cultures since pre-Columbian times.It predates the alternative wheat flour version of the tortilla ("tortilla de harina" or "tortilla de trigo") in all such cultures, as wheat was not grown in the Americas prior to European contact.
