The Indigenous languages of the Americas are the languages that were used by the Indigenous peoples of the Americas before the arrival of non-Indigenous peoples. Over a thousand of these languages are still used today, while many more are now extinct. The Indigenous languages of the Americas are not all related to each other, instead they are classified into a hundred or so language families, as well as a number of extinct languages that are unclassified due to the lack of information on them.
The Ohlone, formerly known as Costanoans, are a Native American people of the Northern California coast. When Spanish explorers and missionaries arrived in the late 18th century, the Ohlone inhabited the area along the coast from San Francisco Bay through Monterey Bay to the lower Salinas Valley. At that time they spoke a variety of related languages. The Ohlone languages make up a sub-family of the Utian language family. Older proposals place Utian within the Penutian language phylum, while newer proposals group it as Yok-Utian.
The Hokan language family is a hypothetical grouping of a dozen small language families spoken mainly in California, Arizona, and Baja California.
The Wintun are members of several related Native American peoples of Northern California, including the Wintu (northern), Nomlaki (central), and Patwin (southern). Their range is from approximately present-day Lake Shasta to San Francisco Bay, along the western side of the Sacramento River to the Coast Range. Each of these tribes speak one of the Wintuan languages. Linguistic and archaeological evidence suggests that the Wintun people probably entered the California area around 500 AD from what is now southern Oregon, introducing bow and arrow technology to the region.
Amerind is a hypothetical higher-level language family proposed by Joseph Greenberg in 1960 and elaborated by his student Merritt Ruhlen. Greenberg proposed that all of the indigenous languages of the Americas belong to one of three language families, the previously established Eskimo–Aleut and Na–Dene, and with everything else—otherwise classified by specialists as belonging to dozens of independent families—as Amerind. Due to a large number of methodological flaws in the 1987 book Language in the Americas, the relationships he proposed between these languages have been rejected by the majority of historical linguists as spurious.
Alsea or Alsean was two closely related speech varieties spoken along the central Oregon coast until the early 1950s. They are sometimes taken to be different languages, but it is difficult to be sure given the poor state of attestation; Mithun believes they were probably dialects of a single language.
Yokuts, formerly known as Mariposa, is an endangered language spoken in the interior of Northern and Central California in and around the San Joaquin Valley by the Yokuts people. The speakers of Yokuts were severely affected by disease, missionaries, and the Gold Rush. While descendants of Yokuts speakers currently number in the thousands, all constituent dialects except for Valley Yokuts are now extinct.
Utian is a family of Indigenous languages spoken in Northern California, United States. The Miwok and Ohlone peoples both spoke languages of the Utian language family. It has recently been argued that the Utian languages and Yokuts languages are sub-families of the Yok-Utian language family. Utian and Yokutsan have traditionally been considered part of the Penutian language phylum.
Plateau Penutian is a family of languages spoken in northern California, reaching through central-western Oregon to northern Washington and central-northern Idaho.
Wintuan is a family of languages spoken in the Sacramento Valley of central Northern California.
Kalapuyan is a small extinct language family that was spoken in the Willamette Valley of Western Oregon, United States. It consists of three languages.
The Tsimshianic languages are a family of languages spoken in northwestern British Columbia and in Southeast Alaska on Annette Island and Ketchikan. All Tsimshianic languages are endangered, some with only around 400 speakers. Only around 2,170 people of the ethnic Tsimshian population in Canada still speak a Tsimshian language; about 50 of the 1,300 Tsimshian people living in Alaska still speak Coast Tsimshian. Tsimshianic languages are considered by most linguists to be an independent language family, with four main languages: Coast Tsimshian, Southern Tsimshian, Nisg̱a’a, and Gitksan.
Takelma is the language that was spoken by the Latgawa and Takelma peoples and the Cow Creek band of Upper Umpqua, in Oregon, USA. The language was extensively described by the German-American linguist Edward Sapir in his graduate thesis, The Takelma Language of Southwestern Oregon (1912). Sapir’s grammar together with his Takelma Texts (1909) are the main sources of information on the language. Both are based on work carried out in 1906 with language consultant Frances Johnson, who lived on to become the last surviving fluent speaker. In 1934, with her death at the age of 99, the language became extinct. An English-Takelma dictionary is currently being created on the basis of printed sources with the aim of reviving the language.
Yok-Utian is a proposed language family of California. It consists of the Yokuts language and the Utian language family.
Klamath, also Klamath–Modoc and historically Lutuamian, is a Native American language spoken around Klamath Lake in what is now southern Oregon and northern California. It is the traditional language of the Klamath and Modoc peoples, each of whom spoke a dialect of the language. By 1998, only one native speaker remained, and by 2003, this last fluent Klamath speaker who was living in Chiloquin, Oregon, was 92 years old. As of 2006 there were no fluent native speakers of either the Klamath or Modoc dialects; however, as of 2019, revitalization efforts are underway with the goal of creating new speakers.
The Ohlone languages, also known as Costanoan, form a small Indigenous language family historically spoken in Northern California, both in the southern San Francisco Bay Area and northern Monterey Bay area, by the Ohlone people. Along with the Miwok languages, they are members of the Utian language family. The most recent work suggests that Ohlone, Miwok, and Yokuts are branches of a Yok-Utian language family.
Marie-Lucie Tarpent is a French-born Canadian linguist, formerly an associate professor of linguistics and French at Mount Saint Vincent University [MSVU], Halifax, Nova Scotia, Canada. She is known for her descriptive work on the Nisga'a language, a member of the Tsimshianic language family, and for her proof of the affiliation of the Tsimshianic languages to the Penutian language group.
Victor Golla (1939–2021) was a linguist and a leading expert on the indigenous languages of California and Oregon, especially the Pacific Coast Athabaskan subgroup of the Athabaskan language family and the languages of the region that belong to the Penutian phylum. He was emeritus professor of anthropology at Humboldt State University and lived in Trinidad, California.
Hometwoli was a dialect of Buena Vista Yokuts spoken in the southern portion of the Tulare Basin of California near Kern Lake.
The Takelma–Kalapuyan languages are a proposed small language family that comprises the Kalapuyan languages and Takelma, which were formerly spoken in the Willamette Valley and the Rogue Valley in Oregon.
