Betoi language  Betoi ("Betoy") or Betoi-Jirara is an extinct language of Colombia and Venezuela, south of the Apure River near the modern border with Colombia. The names Betoi and Jirara are those of two of its peoples/dialects; the language proper has no known name. At contact, Betoi was a local lingua franca spoken between the Uribante and Sarare rivers and along the Arauca. Enough was recorded for a brief grammatical monograph to be written (Zamponi 2003). Betoi is generally seen as an isolate, though Kaufman (2007) included it in Macro-Paesan. Zamponi (2017) observes some lexical resemblances between Betoi and Saliban languages, but considers the similarities to be due to areal influences. Below is a full list of Betoi varieties listed by Loukotka (1968), including names of unattested varieties. Lexicon of Betoi compiled by Zamponi (2003) from various sources:
