Definition & Meaning of "underperson"in English

What is the origin of the term "underperson" and how is it used?

"Underperson" is a term for someone treated as inferior, less than human, or unworthy of basic respect. It entered English in the mid-20th century, influenced by dystopian and sociological language, most notably popularized by science fiction and discussions of class and dehumanization. The word frames people as existing below full personhood, emphasizing systemic exclusion rather than personal insult. It is used in critical, political, or analytical contexts to describe how groups are devalued or stripped of dignity. The term itself is not vulgar, but its meaning is stark and dehumanizing, and it is context-dependent rather than casually insulting.
