Tano is often encountered in the anthropological literature referring to the ancestors of the Arizona Tewa before they relocated to Hopi territory.
Other historical names include Tamos, Tamones, Atmues, Tanos, Thanos, Tagnos, Janos.
The Hopi-Tewa are related to the Tewa communities living in the Rio Grande Valley, such as Santa Clara Pueblo and Ohkay Owingeh.
What is remarkable about this speech community is that the influence of the Hopi language on Hopi-Tewa is extremely small in terms of vocabulary.
Arizona Tewa speakers, although they are trilingual, maintain a strict separation of the languages (see also Code-switching: Example).
