Passing is the ability of a person to be regarded as a member of an identity group or category different from their own, which may include racial identity, ethnicity, caste, social class, sexuality, gender, religion, age and/or disability status. Passing may result in privileges, rewards, or an increase in social acceptance, or be used to cope with difference anxiety. Thus, passing may serve as a form of self-preservation or self-protection in instances where expressing one's true or authentic identity may be dangerous. Passing may require acceptance into a community and can also lead to temporary or permanent leave from another community to which an individual previously belonged. Thus, passing can result in separation from ones original self, family, friends or previous living experiences. While successful passing may contribute to economic security, safety, and avoidance of stigma, it may take an emotional toll as a result of denial of the authentic self and may lead to depression or self-loathing.
Etymologically, the term is simply the nominalisation of the verb pass in its phrasal use with for or as, as in a counterfeit passing for the genuine article or an impostor passing as another person. It has been in popular use since at least the late 1920s.
Historically and genealogically, the term passing has referred to mixed-race, or biracial Americans identifying as or being perceived as belonging to a different racial group. In Passing and the Fictions of Identity, Elaine Ginsberg cites an ad for escaped slave, Edmund Kenney, as an example of racial passing; Edmund Kenney, a biracial slave, was able to pass as white in the United States in the 1800s. In the entry "Passing" for the glbtq Encyclopedia Project, Tina Gianoulis states "for light-skinned African Americans during the times of slavery and the intense periods of racial resegregation that followed, passing for white was a survival tool that allowed them to gain education and employment that would have been denied them had they been recognized as "colored" people." The term passing has since been expanded to include other ethnicities and identity categories. Discriminated groups in North America and Europe may modify their accents, word choices, manner of dress, grooming habits, and even names in an attempt to appear to be members of a majority group or of a privileged minority group.
