Prepositions after adjectives

How to use “alien” with prepositions

Alien is usually followed by to when describing something unfamiliar or contrary to someone.

Quick answer

Use “alien to” for unfamiliarity

Alien to means strange, unfamiliar, or opposed to something. Alien in, alien from, and alien for usually introduce separate ideas rather than completing the adjective.

Such behaviour is alien to our culture.
