Sense: noun/1
All four words refer to someone in a country that is not their own, but they differ in register, duration, and connotation. 'Foreigner' is the most general and everyday term, though it can sound distancing — it simply means someone from another country without saying anything about why they are there. 'Alien' is a formal legal term used in immigration and government documents (e.g. 'resident alien'); outside of legal contexts it can carry a science-fiction or dehumanizing overtone, so it is rarely used in casual conversation. 'Expatriate' (often shortened to 'expat') implies a person living abroad by choice, usually for professional reasons and often with a comfortable lifestyle — it carries a neutral-to-positive tone. 'Immigrant' specifically describes someone who has moved to a new country intending to settle permanently, and it often carries social and political weight that the other terms lack. To choose: use 'foreigner' when you need a simple, neutral description; use 'expatriate' for a professional living abroad temporarily; use 'immigrant' for someone building a new life permanently; reserve 'alien' for official forms.
Etymology
From Latin 'foris' (outside, outdoors), which produced Late Latin 'foranus' (external) and then Old French 'forain' (strange, from outside). English borrowed the word as 'forein' in the 13th century, and the '-er' suffix (meaning 'person who does or is something') was added later to form 'foreigner'. The modern spelling with 'g' was influenced by 'reign' and 'sovereign' during the 16th–17th centuries.
