It means originating from Sentinel (or Northern Sentinel), which is the name of a Gulf of Bengal Island, in the Indian Ocean. It belongs to the Archipelago of Andaman and Nicobar. Name of a very old and unknown language spoken in that same region. It is spoken by an ecnia that has remained isolated and out of contact with today's world.
Unknown language of a strange tribe perhaps from Africa for more than 60 years. 000 years settled on the North Sentinel Island of the Andaman Islands archipelago in the Gulf of Bengal between India and Burma. They have no contact with civilization. In 2018 they shot dead an unwary missionary who approached. Its technical development could correspond to the Neolithic. Looks like they survived the 2004 tsunami.
