The Mango Lexicon, Lexique Mango, contains approximately 1600 words, 1970 sample sentences, and 380 idioms. The research was conducted in N'Djamena during the summers of 2011 and 2012 with Dodom Ndildongar Fidele and Loubeta Miclo. Corrections and additions were made during the summer of 2012 with Gaston Altoloum and with Dodom Ndildongar Fidele. A spell check has been run on the sample sentences to ensure that they contain only words included in the lexicon. The words and sentences have been translated into French in order to make them more useful to readers in Chad.
