Use indigenous to describe a plant, animal or person that is native or original to an area. Though Switzerland is known for its chocolates, chocolate, which comes from the cocoa plant, is indigenous to South America.
Indigenous, aboriginal and native all mean the same thing. Aboriginal, however, is commonly used in connection with Australia, and native with North America. The most neutral of the three terms, indigenous comes from the Latin word, indigena meaning "a native." An indigenous ceremony or religion is one traditionally used by a certain group of people.
