Nahuatl language in the context of "Tepanec"

The Purépecha Empire, also known by the term Iréchikwa, was a polity in pre-Columbian Mexico. Its territory roughly covered the geographic area of the present-day Mexican state of Michoacán, as well as parts of Guanajuato, Guerrero, and Jalisco. At the time of the Spanish conquest, it was the second-largest state in Mesoamerica. The state is also known as the Tarascan Empire.

The empire was founded in the early 14th century and lost its independence to the Spanish in 1530. In 1543 it officially became the governorship of Michoacán, from the Nahuatl exonym for the Purépecha Empire, Michuacān from mich- ("fish"), -ua ("possessor of"), and -cān ("place of") and means "place of fishers."

The Toltec culture (/ˈtɒltɛk/) was a pre-Columbian Mesoamerican culture that ruled a state centered in Tula, Hidalgo, Mexico, during the Epiclassic and the early Post-Classic period of Mesoamerican chronology, reaching prominence from 950 to 1150 CE. The later Aztec culture considered the Toltec to be their intellectual and cultural predecessors and described Toltec culture emanating from Tōllān [ˈtoːlːãːn̥] (Nahuatl for Tula) as the epitome of civilization. In the Nahuatl language the word Tōltēkatl [toːɬˈteːkat͡ɬ] (singular) or Tōltēkah [toːɬˈteːkaḁ] (plural) came to take on the meaning "artisan". The Aztec oral and pictographic tradition also described the history of the Toltec Empire, giving lists of rulers and their exploits.

Modern scholars debate whether the Aztec narratives of Toltec history should be given credence as descriptions of actual historical events. While all scholars acknowledge that there is a large mythological part of the narrative, some maintain that, by using a critical comparative method, some level of historicity can be salvaged from the sources. Others maintain that continued analysis of the narratives as sources of factual history is futile and hinders access to learning about the culture of Tula.

The Isthmus of Tehuantepec (Spanish pronunciation: [tewanteˈpek]) is an isthmus in Mexico. It represents the shortest distance between the Gulf of Mexico and the Pacific Ocean. Before the opening of the Panama Canal, it was a major overland transport route known simply as the Tehuantepec Route. The name is taken from the town of Santo Domingo Tehuantepec in the state of Oaxaca; this was derived from the Nahuatl term Tēcuāntepēc ("jaguar mountain").

Nuevo Reino de Galicia (New Kingdom of Galicia; Galician: Reino de Nova Galicia) or simply Nueva Galicia (New Galicia, Nova Galicia), known in Nahuatl as Chimalhuacán (‘the land of shield bearers’), was an autonomous kingdom of the Viceroyalty of New Spain. It was named after Galicia in Spain. Nueva Galicia's territory consisted of the present-day Mexican states of Aguascalientes, Guanajuato, Colima, Jalisco, Nayarit and Zacatecas.

The Mixtecs (/ˈmɪstɛks, ˈmɪʃ-/ MIS-teks, MISH-) or Mixtecos (Spanish pronunciation: [misˈtekos] – from Nahuatl mixtēcatl [miʃteːkatɬ]; Mixtec: ñuudzahui 'people of Dzahui') are Indigenous Mesoamerican peoples of Mexico inhabiting the region known as La Mixteca of Oaxaca and Puebla as well as La Montaña Region and Costa Chica Regions of the state of Guerrero. The Mixtec culture was the main Mixtec civilization, which lasted from around 1500 BCE until being conquered by the Spanish in 1523.

The Mixtec region is generally divided into three subregions based on geography: the Mixteca Alta (Upper Mixtec or Ñuu Savi Sukun), the Mixteca Baja (Lower Mixtec or Ñuu I'ni), and the Mixteca Costa (Coastal Mixtec or Ñuu Andivi). The Alta is drier with higher elevations, while the Baja is lower in elevation, hot but dry, and the Costa is also low in elevation but much more humid and tropical. The Alta has seen the most study by archaeologists, with evidence for human settlement going back to the Archaic and Early Formative periods. The first urbanized sites emerged here. Long considered to be part of the larger Mixteca region, groups living in the Baja were probably more culturally related to neighboring peoples in Eastern Guerrero than they were to the Mixtecs of the Alta. They even had their own hieroglyphic writing system called ñuiñe. The Costa only came under control of the Mixtecs during the military campaigns of the Mixtec cultural hero Eight Deer Jaguar Claw. Originally from Tilantongo in the Alta, Eight Deer and his armies conquered several major and minor kingdoms on their way to the coast, establishing the capital of Tututepec in the Lower Río Verde valley. Previously, the Costa had been primarily occupied by the Chatinos.

The Popolocan languages are a subfamily of the Oto-Manguean language family of Mexico, spoken mainly in the state of Puebla.

The Popolocan languages should not be confused with the languages called Popoluca spoken in the state of Veracruz, which belong to the unrelated Mixe–Zoquean language family. The term comes from the Nahuatl language and means to speak unintelligibly, which is why Nahuatl speakers called several different unrelated languages "Popolōca". The Nahuatl term was later adopted by the Spanish. The convention now is that the Oto-Manguean languages are referred to as "Popoloca" and the Mixe–Zoquean languages are referred to as "Popoluca", although the latter term is falling into disuse.

Whorf's law is a sound law in Uto-Aztecan linguistics proposed by the linguist Benjamin Lee Whorf. It explains the origin in the Nahuan languages of the phoneme /tɬ/, which is not found in any of the other languages of the Uto-Aztecan family. The existence of /tɬ/ in Nahuatl had puzzled previous linguists, and caused Edward Sapir to reconstruct a /tɬ/ phoneme for Proto-Uto-Aztecan – based only on evidence from Aztecan. In a 1937 paper published in the journal American Anthropologist, Whorf argued that the phoneme was a result of some of the Nahuan or Aztecan languages having undergone a sound change changing the original */t/ to [tɬ] in the position before */a/. The sound law was labeled "Whorf's law" by Manaster Ramer and is still widely – though not universally – considered valid, although a more detailed understanding of the precise conditions under which it took place has been developed.

The situation had been obscured by the fact that often the */a/ had then subsequently been lost or changed to another vowel, making it difficult to realize what had conditioned the change. Because some Nahuan languages have /t/ and others have /tɬ/, Whorf thought that the law had been limited to certain dialects and that the dialects that had /t/ were more conservative. In 1978, Lyle Campbell and Ronald Langacker showed that, in fact, Whorf's law had affected all of the Nahuan languages and that some dialects had subsequently changed /tɬ/ to /l/ or back to /t/, but it remains evident that the language went through a /tɬ/ stage.

Xitle (Nahuatl pronunciation: [ʃitɬe] Nahuatl, "navel") is a monogenetic volcano in the Ajusco range in Cumbres del Ajusco National Park. It is located in the Tlalpan borough in the southwestern part of Mexico City. It is an ash cone volcano with a conical form, round base, altitude of approximately 300m, and a slope between 30° and 40°.

Xitle erupted during the period AD 245-315, according to the results of radiocarbon dating. Among the consequences of this eruption were the formation of the Pedregal de San Ángel lava fields, to the south of the Mexican Federal District. Cuicuilco, one of the most refined cities of Mesoamerica, was destroyed and covered by lava. The subsequent diaspora of the Cuicuilcans, and the attendant diffusion of their culture across most of central Mexico, influenced important cultural changes in the nearby power center of Teotihuacan.
