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, gender identity, sexual identity, or sexual lifestyle, or it may refer to biological intersex physicality, especially with regards to plant and human sexuality. For humans, an androgyne in terms of gender identity is a person who does not fit neatly into the typical masculine and feminine gender roles of their society. They may also use the term ambigender or polygender 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.
