Each year, UNESCO issues an atlas of the world’s endangered languages. Surprising as it may seem, in the United States, there are 75 languages that are considered “critically endangered,” including 40 that are spoken by fewer than 11 people. Among them are Kiksht, the only surviving language of the Chinookan family, spoken by seven elders on the Warm Spring Reservation of north-central Oregon and two on the Yakama Reservation in eastern Washington; Lushootseed, spoken by, at most, five elders near Marysville, Washington; and Yuchi, spoken by five people in northeastern Oklahoma.
