This is a digital version of the Mapudungun – Spanish and Spanish – Mapudungun Dictionary (or Mapudüngun – Wingkadüngun ka Wingkadüngun – Mapudüngun) compiled by Friar Félix José de Augusta, Pascual Segundo Painemilla Ñamcucheu, José Francisco Colüñ, and Domingo Segundo Huenuñamco (among others). The original text dates from 1916, but here we share the updated 2017 edition, edited by Belén Villena. The digital version of the material comes from the Mapudungun Lexicographic Corpus (CORLEXIM), originally compiled by Belén Villena and Andrés Chandía.
