XXI - Ket
Ket is a critically endangered language spoken by the Ket people along the Yenisei River in Siberia, Russia. With fewer than 100 fluent speakers, mostly older adults, Ket is the last surviving member of the Yeniseian language family, making it a linguistic isolate with no known relatives outside its extinct counterparts. Interestingly, some researchers have hypothesized a distant connection between Ket and the Na-Dene languages of North America, though this remains a subject of debate. Efforts to document and revitalize Ket are ongoing, aiming to preserve its unique linguistic and cultural heritage.
