The term "non-person" refers to a person who is disregarded or excluded from society, often due to political or ideological reasons. Synonyms for non-person include outcast, pariah, exile, outlaw, banished, and untouchable. Other words that can be used to describe a non-person are persona non grata, social outcast, marginalized, and rejected. These words all carry a negative connotation and imply a lack of acceptance or belonging. It is important to note that individuals should never be treated as non-persons and should always be treated with respect and dignity, regardless of their social status or beliefs.
