- Tausug (tsg)

Tausūg is spoken by about 1 million people in parts of the Philippines, in Malaysia, and in Indonesia, particularly on the Sulu Archipelago, the Zamboanga Peninsula, Southern Palawan in the Philippines, in Sabah in Malaysia, and in Kalimantan in Indonesia. Tausūg a member of the Visayan branch of Central Philippine languages, which is part of Malayo-Polynesian language family. Tausūg is closely related to the Butuanon language of northeastern Mindanao.

These days Tausūg is written with the Latin alphabet. From the 7th century it was written with a version of the Arabic alphabet based on the Malaysian Jawi script. Tausūg was also written with a version of the Baybayin script known as Luntar Sug from the 7th century until the 16th century.

Tausug is primarily spoken in the Sulu Archipelago, which aside from the island of Sulu, also includes the Tawi-Tawi chain of islands and the island of Basilan. It is a lingua franca spoken in different areas/islands of the archipelago.

Due to migration, the language is also spoken alongside other local languages in the Zamboanga Peninsula (e.g., Cebuano and Chavacano), which includes the provinces of Zamboanga del Norte, Zamboanga Sibugay and Zamboanga del Sur and Zamboanga City. It is also spoken in Southern Palawan and in Eastern Sabah, Malaysia.
