The "Jirajarana" family or "Jirajirana" is a group of extinct languages spoken in the western regions of Venezuela, Falcon and Lara. It is believed that the languages went extinct at the start of the 20th century. The Jirajara languages are considered to be semi-isolates. Adelaar and Muysken point out certain lexical similarities with Timote-Cuica languages, and typological similarities with Chibcha languages. But the limited data does not allow validity to any similarities between the Jirajarana and Betol languages, particularly for the similarities of the ethnonyms.
