Dieu language

The Sohainesian language (Sohainesian: 㗂嘉定; Shạ́ng Su Hâi) is language within the Vietic branch of Austroasiatic languages, originating from. It is the official language in Sohainesia, and a common language in Vietnam. It is written using Chinese characters. Sohainesian is viewed as a vital and inseparable part of the cultural identity for its native speakers in Southern Vietnam, Sohainesia, as well as in overseas communities.

Although Sohainesian has a nearly identical vocabulary to Vietanmese, is mutually unintelligible with other forms of Vietnamese, because of its different phonology. It was developed in the 15th century by Vietnamese scholars and governors of Sohainesia, and maintained its way during French rule. Another writing system, Lama Sohainesian, is mostly used by the Catholic minority.

History
Before French colonization, Sohainesian was considered as a dialect of Vietnamese due to mutual intelligibility, but was later designated as its own language due to Vietnam adopting chữ Quốc ngữ as the official script.

When France invaded Vietnam in the late 19th century, French gradually replaced Chinese as the official language in education and government. The colonial administrators discouraged the use of Chinese characters in favor of chữ Quốc ngữ, but the script never gained popularity in Sohainesia, due to considerable opposition to the script. This caused the Sohainesian language to separate from Vietnamese.

Since the end of French rule, the Sohainesian government has attempted to limit usage of Western loans by coining new words (neologisms). For instance, for the word "doll", Sohainesian publications are manadated to use 人類𨔈 (human toy) in lieu of 芣𠶎, a French loanword. Some previously common English loanwords have fallen out of use with the adoption of indirect translations, such as the word for "club", formerly 俱樂部 (kạu lǎk boǔ), now 人機關 (nyạn kạ̄ kwān), meaning "people's organization".
