I understood that the word Aborigine was a noun and aboriginal was an adjective. Can you clarify please?
• noun 1 an aboriginal person, animal, or plant. 2 (Aborigine) an Australian aboriginal.
—ORIGIN from Latin ab origine ‘from the beginning’
• adjective 1 inhabiting or existing in a land from the earliest times or from before the arrival of colonists; indigenous. 2 (Aboriginal) relating to the Australian Aboriginals.
• noun 1 an aboriginal inhabitant. 2 (Aboriginal) a member of one of the indigenous peoples of Australia.
