Sehwangnese languages

The Sehwangnese Languages (셰황으-군 (Western Sehwangnese) 시황어군 (Central Sehwangnese) 세휑말들 (Eastern Sehwangnese)) are a family of three languages belonging to the Sincheon language family and spoken in the Sehwang Federation. These languages form the mainstream language in Sehwang, but through the middle of the 20th century, they no longer have great power as the upper layer of bilingual languages. After the middle of the 20th century, Sehwang's language use is undergoing a transition from bilingualism to multilingualism due to the continued coexistence with the natives for hundreds of years.
