Agni-Kuchi languages

The Arshi-Kuchi or Arśi-Kuči languages, often but improperly called Tocharian languages, are an extinct language family belonging to the Indo-European languages; they are chiefly attested during the Early Middle Ages in the Tarim Basin (in today's Xinjiang, Central Asia).

This language family is known thanks to writings in two neighbor languages of the Tarim Bassin:
 * Arshi (or Arśi or Tocharian A)
 * Kuchi (or Kuči or Tocharian B).
