Sentinelese

Sentinel +‎ -ese

Sentinelese (plural Sentineleses or Sentinelese)

1. (chiefly in the plural) A member of an indigenous people of the Andaman Islands, in the Bay of Bengal. They inhabit North Sentinel Island.

As with other terms for people formed with -ese, the countable singular noun in reference to a person (as in "I am a Sentinelese", "writing about Sentinelese cuisine as a Sentinelese") is uncommon and often taken as incorrect. In its place, the adjective is used, by itself (as in "I am Sentinelese") or with a word like person, man, or woman ("writing about Sentinelese cuisine as a Sentinelese person").

Sentinelese

1. The language of these people, unknown but presumed to belong to one of the Andamanese language families.
