Where does the word alien come from?

The word "alien" originates from the Latin word "alienus," meaning "belonging to another." It entered English in the 14th century and initially referred to something or someone foreign or strange. Over time, the meaning evolved to encompass the concept of being from another place, particularly extraterrestrial beings. This shift in meaning occurred in the 19th century, driven by the growing fascination with the possibility of life beyond Earth.
