Other forms: outcasts
An outcast is somebody pushed out of a group. A social outcast, treated as an outcast, an outcast from the village.
The exclusion is by the group rather than by choice, which is what separates an outcast from a recluse. It is a heavy word and belongs to communities small enough for exclusion to bite. Note pariah, which is close and rather stronger; and that outcast is an old past participle used as a noun, from a verb outcast that English no longer has.
