Androgyny is a term derived from the Greek words ανήρ, stem ανδρ- (anér, andr-, meaning man) and γυνή (gyné, meaning woman), referring to the combination of masculine and feminine characteristics. This may be as in fashion, sexual identity, or sexual lifestyle, or it may refer to biologically inter-sexed physicality, especially with regards to plant and human sexuality.

For humans, an androgyne ( /ˈændrədʒaɪn/ AN-drə-jyn) in terms of gender identity, is a person who does not fit cleanly into the typical masculine and feminine gender roles of their society. They may also use the term ambigender to describe themselves. Many androgynes identify as being mentally "between" woman and man, or as entirely genderless. They may identify as non-gendered, genderneutral, agendered, between genders, genderqueer, multigendered, intergendered, pangender or gender fluid.^{[citation needed]}

The Bem Sex Role Inventory is one of the most widely used gender measures and was constructed by the early leading proponent of androgyny, Sandra Bem (1977). Based on their responses to the items in the Bem Sex-Role Inventory, individuals are classified as having one of four gender-role orientations: masculine, feminine, androgynous, or undifferentiated.
