Na, also known as Sara Kaba Na, is a Sara Kaba language used by some 35,000 speakers in the area around Kyab in southern Chad. There are also a large number of speakers in the Chadian capital N djamena. This lexicon contains approximately 2780 words, 2000 sample sentences, and 580 idiomatic expressions. The Na data was gathered in N djamena during the summers of 2012 et 2013, working principally with Kod Koutou. The work also contains a 42 page introduction explaining the basic features of the phonology, morphology and syntax of the language. This Na lexicon provides an excellent starting point for a future dictionary of this language.
