Privilege is a special right, or advantage available only to a particular person or group of people. The term is commonly used in the context of social inequality, particularly in regard to social class, race, age, sexual orientation, gender, and disability. Two common examples would be having access to a higher education and housing. Privilege can also be emotional or psychological, regarding personal self-confidence and comfort, or having a sense of belonging or worth in society. It began as an academic concept, but has since become popular outside of academia.
