What do you call a person who is rejected from society or home?

The term "pariah" accurately describes a person who is rejected from society or home. It originates from South India and refers to individuals who belong to a marginalized social group, often facing social ostracism. In contemporary usage, it encompasses anyone who is shunned or excluded from the community, thus fitting the context of a person experiencing significant rejection.

While "outcast" also signifies someone who has been rejected, it can imply a broader range of social exclusions, whereas "pariah" carries a connotation of a person who is not only excluded but is also often despised or looked down upon by society.

"Exile" refers specifically to someone who is forced to leave their homeland, usually for political reasons, which may not encompass the social stigma involved in being a pariah.

"Refugee" typically pertains to a person who has fled from their country due to war, persecution, or disaster, and while refugees may face societal rejection, the term does not inherently imply rejection by society itself but rather a context of displacement.

Thus, "pariah" is the most precise term for someone rejected both from society and their home.
