Sittapinian language

Sittapinian, often known as Phesasit or Phexaxit ( [pʰes̠aːs̠iʈ]), formally Phesabhomahuti ( [pʰes̠aːbʱomaːhʊti]), is a language isolate influenced by, Nesionytan and language families, and, predominantly spoken in Sittapini. It is one of the few languages isolates in the Nesionytan Islands, with the closest language being Chumaren, which is largely different from it. Sittapinian is officially registered as Phesasit, and is used in most sources, but the common name is still Sittapinian. It is the sole official language of Sittapini, and is a recognized minority language in the Kanuzunda Islands. Sittapinian has its own writing system, which is still currently used.

Sittapinian developed in the 5th century when humans from Southeast Asia settled in the island of Sittapini. It mixes elements from Kra-Dai, Sanskrit, and Nesionytan languages. Early Sittapinian tribes did not write the language and had no voiced consonants, but both they were developed in the 6th century. At that period, the language used to be written in the Kubusa script, borrowed from the Ulakisonians. Middle Sittapinian began development in the 10th century after voiced unaspirated and voiced aspirated consonants began to merge, and the schwa sound replaced with a long 'a' sound, which merged with short 'a'. Modern Sittapinian was developed in the 1800s, with the creation of its own writing system.

Sittapinian is the native language of 80% of Sittapini's population, and has little mutual intelligibility with Tamayar and Bhijin. Constitutionally, the language is referred to its formal name, even after Bhomahuti being renamed to Sittapini in 1923.

Etymology
The language is formally called Phesabhomahuti, which literally means "language of Bhomahuti". It is often known as Phesasit, which means "language of the country". Earlier, Sittapinian was known as "muang jhai", literally 'human talk'. Currently, Muangjhai is only used as a name of a Sittapinian dialect spoken in the west of the island.
