The Tausūg or Suluk people are an ethnic group of the Philippines, Malaysia and Indonesia. The term Tausūg was derived from two words tau and sūg (or suluk in Malay) meaning "people of the current", referring to their homelands in the Sulu Archipelago. Sūg and suluk both mean the same thing, with the former being the phonetic evolution in Sulu of the latter (the L being dropped and thus the two short U's merging into one long U). The Tausūg in Sabah refer to themselves as Tausūg but refers to their race as Suluk as documented in official documents such as birth certificates in Sabah, which are written Malay. The Tausūg are part of the wider political identity of Muslims of Mindanao, Sulu and Palawan known as the Moro ethnic group, who constitute the third largest ethnic group of Mindanao, Sulu and Palawan.
