IPA: /nɒnˈpɜːrsən/
KK: /nɑnˈpɜrsən/
A person whose existence is deliberately ignored or hidden, often for political or ideological reasons, or someone who has no social or legal status.
In some societies, nonpersons are erased from history and denied basic rights.
Nonperson → It is formed from "non-" (meaning not) and "person" (from Latin "persona", meaning a character or individual). The word "nonperson" refers to something that is not considered a person or lacks the qualities of a person.
Think of 'non-' meaning 'not' and 'persona' meaning 'individual' — so a nonperson is something that is not an individual.
