A man is a male human. The term man (irregular plural: men) is used for an adult human male, while the term boy is the usual term for a human male child or adolescent human male. However, man is sometimes used to refer to humanity as a whole. Sometimes it is also used to identify a male human, regardless of age, as in phrases such as "Men's rights".
The term "manhood" is used to refer to the various qualities and characteristics attributed to men such as strength and male sexuality.
