Tangut people
Tangutology or Tangut studies is the study of the culture, history, art and language of the ancient Tangut people, especially as seen through the study of contemporaneous documents written by the Tangut people themselves. As the Tangut language was written in a unique and complex script and the spoken language became extinct, the cornerstone of Tangut studies has been the study of the Tangut language and the decipherment of the Tangut script.
