Ingain language

Ingain is an extinct Jê language of Brazil, closely related to the Southern Jê languages Kaingáng and Laklãnõ (Xokléng). Kimdá may have been a dialect. Ingain was spoken along the middle Paraná River, from the Iguatemi River in the north to the Arroyo Yabebiry in the south.

Related "South Kaingáng" languages were:
 * Guayana / Wayana / Gualachí / Guanhanan - extinct language once spoken between the Uruguay River and Paraná River, Rio Grande do Sul, Brazil
 * Amhó or Ivitorocái - extinct language from Riacho Ivitoracái, Paraguay. Listed as separate from the Ingain cluster by Mason (1950).
