What term describes a social outcast?

The term "pariah" specifically refers to an individual who is rejected or ostracized by society or a particular group, making it synonymous with a social outcast. This word originates from a Tamil term for a member of a low caste, historically marginalized in social contexts. It embodies the essence of social exclusion and emphasizes the negative connotations associated with being viewed as an outcast.

The other terms do not carry the same meaning. "Outlier" generally describes something that is different from the norm or statistical average, often used in data analysis. "Insider," in contrast, refers to someone who is part of a group or has privileged access to certain knowledge, which is the opposite of being an outcast. "Stranger" refers to someone unknown or unfamiliar, lacking the specific implications of societal rejection that "pariah" conveys. Therefore, "pariah" is the most accurate term that captures the notion of a social outcast.
