Dagaare is the language of the Dagaaba people of Ghana, Burkina Faso, and Ivory Coast. It has been described as a dialect continuum that also includes Waale and Birifor. Dagaare language varies in dialect stemming from other family languages including: Dagbane, Waale, Mabia, Gurene, Mampruli, Kusaal, Buli, Niger-Congo, and many other sub languages resulting in around 1.3 million Dagaare speakers. Throughout the regions of native Dagaare speakers the dialect comes from Northern, Central, Western, and Southern areas referring to the language differently. Burkina Faso refers to Dagaare as Dagara and Birifor to natives in the Republic of Côte d'Ivoire. The native tongue is still universally known as Dagaare. Amongst the different dialects, the standard for Dagaare is derived from the Central region's dialect. Southern Dagaare (or Waale) also stems from the Dagaare language and is known to be commonly spoken in Wa and Kaleo.

Dagaare is a tonal language with a two-level tone system with a downstep high tone. The Dagaare tone has two basic functions, namely a lexical and a grammatical function. Its lexical function concerns differences in lexical semantics, such that differing in tone but not in morphosyntactic form triggers different semantics. Its grammatical function is responsible for cases in which different tone markings on a segment result in different semantics of that expression.
