Kasem is considered one of the Grũsi or Gurunsi languages, a group of Gur languages, which form part of about 20 languages spoken by the people of Gurunsi. The Kasem as part of the Gur languages is spoken in the Upper East Region and Burkina Faso.
The language of the Kasena people called Kasem is spoken mostly in three traditional states in the Upper East Region of Ghana namely Paga, Navro and Chiana traditional areas. People in these three traditional areas and their affiliate communities are the speakers of the language. The people that speak the language are normally referred to us Kasena or Kasembu.
The Kasena people appreciate variations in the Kasem language spoken by the various communities in the three traditional states mentioned above. Variations in the language can either be described as White Kasem ‘Kasem-pwoŋo or Black Kasem ‘Kasen – zwono. The one that is believed to be easily and friendly spoken in many communities are known as the Kasem pwoo whilst the Kasem zwono appears to be quite heavy, pure and difficult to understand.
Though they may be several differential dialects of the Kasem Language, both within and outside the boarders of the Kasena people, there are broadly three main Kasem dialects spoken in the Upper East Region of Ghana. These are Navannea Kasem, Paga Kasem known as Paga-tiini and Chiana Kasem also known as Chiana-tiini.
