Tengos

Tengos (tengos xut [tʰeɳ̩gos xɯt] lit. ‘word sky’) or Tengosic is an extinct language isolate spoken by the ancient Xunten, who probably constituted part of the Kangju federation by the ancient oasis of Tashkent in Central Asia. Tengos has no demonstrable relatives and is generally classified a language isolate. Using an adapted version of Akkadian cuneiform, Xunten writers have left over 300 lengthy inscriptions, which has allowed the understanding of a significant amount of the language.
