alien
Not from here
A good way to corral all the meanings of alien is to remember that it comes from a word that means other in the sense of not you.
Anything strange and unfamiliar can be called alien, especially if you also want to imply a dislike for it.
As a noun, an alien is someone different from you because of their origin – in another country or on another planet.
