The Palta language is an extinct language of the Ecuadorian Amazon, formerly spoken by the Palta people.
Based on this, Jacinto Jijón y Caamaño (1936) classified it as a Jivaroan language. Kaufman (1994) states that there is "little resemblance", but Adelaar (2004) 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, and Torero (1993) notes that the last resembles Aguaruna (Jivaroan) namák(a) 'river' as well.
Mason (1950) also lists Malacata as an alternate name for Palta.
It is attested by only a few words: yumé 'water', xeme 'maize', capal 'fire', let 'firewood' (Jiménez de la Espada, 1586), and some toponyms.
