Palta language
The extinct Palta language of the Ecuadorian Amazon is attested by only a few words: yumé 'water', xeme 'maize', capal 'fire', let 'wood', and some toponyms. Based on this, Jacinto Jijón y Caamaño classified it as a Jivaroan language. Kaufman states that there is "little resemblance", but Adelaar finds the connection reasonable. In addition to these four words are toponyms, which commonly end in -anga, -numa, -namá. The latter two suggest the Jivaroan locative case suffix -num ~ -nam, though Torero notes that the last resembles Aguaruna namák 'river' as well.
Mason also lists Malacata as an alternate name for Palta.
