Original sentence: Classical Otomi is the name used for the Otomi spoken at the eve of the spanish Conquest
Edited sentence: A high degree of intermarriage and mixing between Otomian and Nahuan groups took place and some of the most powerful city-states of the 10th to 13th centuries are thought to have been bilingual in Otomi and Nahuatl, for example Azcapotzalco.After the fall of Teotihuacan the Nahua peoples began to arrive in central Mexico displacing Oto-Manguean peoples and rapidly becoming the dominant group in the area.At first Xaltocan was superior, but as Cuautitlan allied with Tezozomoc of Azcapotzalco Xaltocan was conquered and razed and the majority of its population fled to the powerful Otomi seignority of Metztitlan in Eastern Hidalgo, while others were allowed to settle in the lands of Texcoco at the place thenceforth called Otumba (from the Nahuatl Otōmpan "place of the Otomi"), and in Tlaxcala, where Otomi is still spoken to this day.Classical Otomi is the name used for the Otomi spoken at the eve of the spanish Conquest and in the first centuries of colonial rule.For example the Nahuatl placename Tenochtitlān "place of Opuntia cactus" was rendered as ɔnbondo in Otomi, with the same meaning.Founded in the twelth century the Otomi citystate of Xaltocan held a dominant position in the basin of Mexico.In the late fourteenth century Xaltocan undertook a prolonged war against the Nahua state of Cuautitlan.Some even speculate that the Acolhua people and their most famous king Nezahualcoyotl, may have had Otomi as their first language.The Otomi often translated names of places or rulers into Otomi rather than using the Nahuatl names.The Precolumbian Otomi did not have a proper writing system, but the largely ideographic Aztec writing could be read in Otomi as well as Nahuatl.The main argument for this hypothesis being that most of central Mexico is known to have been inhabited by speakers of the Oto-Pamean languages before the arrival of Nahuatl speakers
