very strange or unfamiliar
Very new and strange to someone; not part of their normal life, ideas, or feelings.
Μοτίβο χρήσης:
alien to [someone/something]
Συχνό λάθος:
Learners sometimes use "alien" instead of "strange" or "weird" in very casual speech. While this is not wrong, "alien" is stronger and sounds more formal or dramatic. Also, many learners do not use the common pattern "alien to [someone/something]"; this pattern is natural and should be learned as a chunk.
Συνώνυμα
strange (More general and common; does not always suggest strong difference from someone's normal world.)
Αντώνυμα
familiar (Describes something known and comfortable, the opposite of being strange or different.)

non-citizen living in a country
A person who lives in a country but is not a citizen of that country, used mainly in law and official writing.
Μοτίβο χρήσης:
an alien [with/without legal status]
Συχνό λάθος:
Learners sometimes use "alien" for foreign people in everyday conversation. In modern English, this can sound old‑fashioned or offensive. It is safer to say "foreigner", "immigrant", or "a person from another country" in neutral speech, and reserve "alien" for legal or historical contexts.
Συνώνυμα
foreigner (More common in everyday speech and less legal; can sound neutral or negative depending on tone.)
Αντώνυμα
citizen (A person who legally belongs to a country, the opposite of a non‑citizen in that country.)

from another country or culture
From another country or culture; not native to that place.
Μοτίβο χρήσης:
alien [culture/customs/species/law]

Learners may overuse "alien" instead of "foreign". In most everyday situations, "foreign" is the natural choice. "Alien" sounds more formal or literary, or appears in technical phrases like "alien species" in environmental science.
Συνώνυμα
foreign (More common and neutral; used in all types of speech.)
Αντώνυμα
native (Describes something originally from the place, the opposite of being from outside.)
