Masculinity - Wikipedia, the free encyclopedia

Masculinity comprises culturally of the traits assigned to the male in various contexts. The word masculine can refer to:

The property of being biologically male, more precisely expressed in biology as "sex"
A gender role or behaviour traditionally associated with males
Grammatical gender, an inflection of nouns, largely derived from gender role association
Masculinity is sometimes used as a synonym for manhood. The antonym of masculinity is femininity; femininity in men is sometimes called effeminacy.

Masculinity is a gender role associated with male humans and an indicator of social status much as wealth, race or social class. Greater masculinity usually brings greater social status for males, and many English words such as virtue (from the Latin vir for "man'", also used in words such as vim and vigor and virulent) reflect this, implying a clear association with strength. Masculinity is associated more commonly with adult men rather than younger boys as a key characteristic of social persona. The corresponding gender role for females is called femininity. To assert the presence of femininity or masculinity in a member of the opposite gender is to mark them as unusual, often in an undesirable way. In non-human primates, the corresponding trait is called dominance in both sexes, expressed as relative position within a gender group, where human terms such as "masculinity" almost never used in general ethology.

Femininity - Wikipedia, the free encyclopedia

Femininity comprises the physical and mental attributes associated with the female sex. Some of these attributes can be traced to the female reproductive role. Others are rooted in the socialization of a girl's early development and adjusted throughout adulthood by picking up or reacting to societal cues. Feminine characteristics are expressed through female gender roles, which can vary between societies and eras but often include notions of motherhood, being like a princess or queen, and the tension between being virginally pure versus being sexually attractive.
