All of the Jirajaran languages appear to have become extinct in the early 20th century.

[1] Based on adequate documentation, three languages are definitively classified as belonging to the Jirajaran family:[1] Loukotka includes four additional languages, for which no linguistic documentation exists:[2] Mason (1950) lists:[3] The Jirajaran languages are generally regarded as isolates.

Adelaar and Muysken note certain lexical similarities with the Timotean languages and typological similarity to the Chibchan languages, but state that the data is too limited to make a definitive classification.

[5] Jolkesky (2016) notes that there are lexical similarities with the Sape, Timote-Kuika, and Puinave-Kak language families due to contact.
