Femininity (also calle womanliness) refers to qualities and behaviors judged by a particular culture to be ideally associated with or especially appropriate to women and girls. Distinct from femaleness, which is a biological and physiological classification concerned with the reproductive system, femininity principally refers to secondary sex characteristics and other behaviors and features generally regarded as being more prevalent and better suited to women, whether inborn or socialized. In traditional Western culture, such features include gentleness, patience and kindness.
