The term femininism (also capitalized as Femininism) is related to the adjective feminine. The concept originates as far back as the 19th century. It is a philosophy of elevating and attempting to live by traits or virtues that accentuate the femininity of women, while still supporting intellectual equality between the sexes. It is acceptance of womanhood as strength.
Unlike the similar-sounding feminism, femininism has a distinct meaning associated with gender differences rather than gender equality, though historically it has also been used to mean feminism.
