The Batak languages are a group of closely related languages spoken by the Batak people in northern Sumatra, Indonesia. This language family includes several distinct languages, such as Toba Batak, Karo Batak, Simalungun Batak, Pakpak Batak, and Mandailing Batak. Each language has its own unique characteristics, but they share a common linguistic heritage. These languages belong to the Austronesian language family and are primarily used in daily communication, cultural expressions, and traditional ceremonies among the Batak communities. The preservation of these languages is important for maintaining the rich cultural identity of the Batak people.
