A girl is a young female human, usually a child or an adolescent. When a girl becomes an adult, she is accurately described as a woman. However, the term girl is also used for other meanings, including young woman, and is sometimes used as a synonym for daughter, or girlfriend. In certain contexts, the usage of girl for a woman may be derogatory. Girl may also be a term of endearment used by an adult, usually a woman, to designate adult female friends. Girl also appears in portmanteaus like showgirl, cowgirl, and schoolgirl.
