The Opuo (Opuuo, Opo) language, or Tʼapo, is a Koman language spoken by the Opo people of Ethiopia and South Sudan. It has a lexical similarity of 24% with Komo. The language is also called Opo-Shita, Opo, Opuo, Cita, Ciita, Shita (along with Dana), Shiita, Ansita, Kina, and Kwina. The self-name for the language is Tʼapo. "Langa" is a derogatory term for its speakers used by the Anuak.[1]
An early record of this language is a list of 32 village names and a wordlist dated February 1883 by Juan Maria Schuver, where he calls the language "Gambiel".[3]
