The word 'native' typically refers to something originating from a specific place or the people who are the original inhabitants of a region. This term can indicate being endemic or indigenous to an area. Therefore, the correct antonym would denote something that is not originating from the same place, rather from an outside or different area.
Let's examine the provided options:
- Endemic: Refers to a species or characteristic native to a particular area or environment.
- Indigenous: Means originating or occurring naturally in a particular place; native.
- Genuine: Authentic or real; not related to origin.
- Foreign: From, in, or characteristic of a country or language other than one's own; not native.
Considering the meaning of the options, the antonym for 'native' is 'Foreign', as it signifies something originating from outside the native area.
