Santiago de Querétaro, most commonly known as Querétaro, is the capital and largest city of the state of Querétaro, located in central Mexico. It is part of the macroregion of Bajío. It is 213 kilometers (132 mi) northwest of Mexico City, 63 kilometers (39 mi) southeast of San Miguel de Allende and 200 kilometers (120 mi) south of San Luis Potosí. It is also the seat of the municipality of Querétaro, divided into seven boroughs. In 1996, the historic center of Querétaro was declared a World Heritage Site by UNESCO.

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.
