Tsat is a member of the
Malayo-Polynesian group within the Austronesian language family, and is one of the
Chamic languages originating on the coast of present-day
Vietnam. It is thus closely related to
Acehnese,
Cham and
Jarai. The origins of the Utsul are obscure. Though they are undoubtedly Cham, and therefore primarily descended from immigrants from the
Champa states of modern-day southern Vietnam, it is unclear when they arrived in Hainan and to what extent other
Hui Muslim groups contributed to their ethnogenesis. Thurgood, Thurgood, and Li (2014) record several traditional accounts, which mention
Tang-dynasty
Xinjiang,
Song Guangdong, and post-
Vijaya Champa as distinct legendary origins of the Utsul people. These accounts - all of which are considered to have some basis in historical fact - reveal a strong emphasis on Muslim religious identity rather than ethnolinguistic heritage, compounded by the conflation of Muslims in the region as "Hui" regardless of language. A migration from Champa after 968 AD (the fall of
Indrapura) appear to be the most significant contributor to the modern Utsul identity, although another migration in the fifteenth century is also recorded in Chinese texts. Thurgood, Thurgood, and Li's grammar distinguishes between an older form of the language, "Colloquial Cham", and a more recent "Mandarinised" version. Their source for the former is Li and Thompson's 1981 research among speakers since deceased; it is doubtful whether the less Mandarinised variety is still spoken in Sanya. ==Phonology==
