Tausug (Bahasa Sūg; Jawi: بَهَسَ سُوگ; Bahasa Suluk) is an Austronesian language spoken in the province of Sulu in the Philippines and in the eastern area of the state of Sabah, Malaysia, by the Tausūg people. It is widely spoken in the Sulu Archipelago (Sulu, Tawi-Tawi, and Basilan), the Zamboanga Peninsula (Zamboanga del Norte, Zamboanga Sibugay, Zamboanga del Sur, and Zamboanga City), southern Palawan, and Malaysia (eastern Sabah). Tausug has some lexical similarities or near similarities with Surigaonon language of the provinces Surigao del Norte, Surigao del Sur, and Agusan del Sur and with the Butuanon language of Agusan del Norte; it has also some vocabulary similarities with Sugbuanon, Bicolano, and with other Philippine languages. Many Malay and Arabic words are found in Bahasa Sūg. In English, the language is primarily known as Tausug (i.e., Tausug language "language of the Tausug people"). The local name of the language is bahasa Sūg (Sulu language). The term Tausūg (tau Sūg, meaning "people of Sulu") is derived from two words: tau ("person") and Sūg (The transformation of "Sūk", itself the contraction of Sūlūk). Thus, in Tausug, Tausug refers to people while Bahasa Sug refers to the language. Several scholars postulate that "Sūlūk" derives from "Ahl ul-Sūlūk", or "people of the path (to Allah)," in reference to the Islamic missionaries who arrived to spread the religion of Islam. Meanwhile, a similar sounding word "sug", which means "water-current", has been given by a number of writers as the etymologic source of the term; the two words, even if similarly pronounced, are not related. In the past, the language has also been simply referred to using the generic term "Moro". Tausug is an Austronesian language. It is classified by linguists as being a member of the Bisayan languages family, which includes Cebuano and Waray. In particular, it has many similarities with the Surigaonon language of the provinces Surigao del Norte, Surigao del Sur and Agusan del Sur and with the Butuanon language of Agusan del Norte – both spoken in northeastern Mindanao; hence, Zorc (1977) groups these three languages as part of a "South Bisayan" grouping.
