Gender is the perceived masculinity or femininity of a person or characteristic. A person's aggregate gender is complex, encompassing countless characteristics of appearance, speech, movement and more. This aggregate gender is often not easily categorized simply, although society tends to assume a simply binary organization. Gender meanings are constantly being renegotiated, as, for example, the color pink, considered masculine in the early 1900s, is now seen as feminine, and vice versa for blue. Gender is also evolving in this usage from noun to adjective: it is increasingly being seen as an attribute (like color) rather than as a distinct entity in itself.
The English noun "gender" is derived from the Old French word genre, meaning "kind of thing". It goes back to the Latin word genus (meaning "kind", "species").
Gender is often, but decreasingly, used as a synonym for Sex, referring to the physical polarity of anatomy which is commonly used to differentiate male from female. This has given rise to the use of "gender" in manufacturing, to denote polarity of mating connectors that have "male" plugs and "female" sockets.nike free run 5.0 nz
