Just like with spoken languages, there are different variations of sign language. In Australia, its Auslan, and in America, it's American Sign Language, or ASL.
But in one American state, there's another distinct type of sign language, which unitl very recently was undocumented.
It's called Hawai'i Sign Language (HSL) and it's the indigenous language of deaf people in Hawai'i.
Thanks to work done by research group based in the Department of Linguistics at the University of Hawai'i at Manoa, HSL has now been formally recognised as a unique language of its own, and efforts are underway to record and conserve it.
