Hawaiian language first appeared in XIX century in Hawaii as main language of native speakers. Only 1 thousand people speak Hawaiian. The language is considered to be critically endangered.
After active contacts with Europeans and North Americans begin, the Hawaiian language gradually gives way to English. Since the annexation of the Hawaiian Islands by the US in 1898, the development of the Hawaiian language greatly decreases, because of influx of English speakers.
Hawaiian culture is very special. Its poetry is irreplaceable, and everybody heard about unique Hawaiian music. It also had influenced other languages. For example, Hawaiian aloha is one of the ways to say hello in English now.
Despite small number of speakers, Hawaiian is unlikely to die out. In order to revive the language, private schools of Hawaii started offering students to study Hawaiian language deeply.
I'll leave here some examples of this language in case you're interested:
hale — house; kai — sea; ohana — family; Hawaiʻi — Hawaii; ʻŌlelo Hawaiʻi — Hawaiian language
I chose this language because nothing is similar to Hawaiian culture. I would like to know Hawaiian to read some poetry, but I don't think I'll ever start studying
