Definition

Usage & Nuances

Most often used in movies, science fiction, and casual talk about life in space. Common phrases include 'alien invasion', 'alien spaceship', and 'believe in aliens'. Be careful: in legal or official English, 'alien' can mean a foreign national, but that use sounds formal or old-fashioned in everyday speech.
