Mexico City is the capital and largest city of Mexico, and the most populous city in North America. Mexico City is one of the most important cultural and financial centers in the world. It is located in the Valley of Mexico within the high Mexican central plateau, at an altitude of 2,240 meters (7,350 ft). The city has 16 boroughs or demarcaciones territoriales, which are in turn divided into neighborhoods or colonias.

Otomi is an Oto-Pamean language spoken by approximately 240,000 indigenous Otomi people in the central altiplano region of Mexico. Otomi consists of several closely related languages, many of which are not mutually intelligible. The word Hñähñu has been proposed as an endonym, but since it represents the usage of a single dialect, it has not gained wide currency. Linguists have classified the modern dialects into three dialect areas: the Northwestern dialects are spoken in Querétaro, Hidalgo and Guanajuato; the Southwestern dialects are spoken in the State of Mexico; and the Eastern dialects are spoken in the highlands of Veracruz, Puebla, and eastern Hidalgo and villages in Tlaxcala and Mexico states.
