“Homosexual” is a medical and legal term to refer to non-heterosexual sexualities. The term as such was invented in the mid-19th century as an abnormal identity category to distinguish a person who engaged in sexual acts with another of the same sex. Homosexuality has been and continues to be considered sinful, a mental illness or even criminal in several places across the world. The term, and its abbreviated form homo is sometimes used as derogatory or curse word.
