Unisex is an adjective indicating something is not sex-specific, i.e. is suitable for any type of sex.[1][2] The term can also mean gender-blindness or gender neutrality.
The term 'unisex' was coined in the 1960s and was used fairly informally. The combining prefix uni- is from Latin unus, meaning one or single. However, 'unisex' seems to have been influenced by words such as united and universal, in which uni- takes the related sense shared. Unisex then means shared by sexes.[3]
