Kiowa call themselves Ka'igwu, Cáuigù or Gaigwu, most given with the meaning "Principal People". The first part of the name is the element Kae-, Cáui- or Gai- which means the Kiowa themselves – it may derive from the word ka' (mother) or from ka-a (a type of spear with feathers along its length). The true origin is lost. Kae-kia means a Kiowa man; Kae-ma is a Kiowa woman. The second element -gua refers to "men or people", so the meaning of the two elements is "Kiowa people"; to express "Principal People" (sometimes "Chief People") or "genuine, real or true People" in Kiowa is to add the ending -hin.
