What does boy mean?
A boy is a male human child or adolescent, as distinct from a girl on one side and a man on the other. The word appears constantly in everyday speech, from literal description ('a ten-year-old boy') to informal address among friends ('Come on, boys!'), and it anchors many fixed expressions such as 'boys will be boys' and 'the boy next door'. As an interjection, it adds emphasis or surprise: 'Boy, am I tired.' Historically, boy could also denote a male servant regardless of age, a sense now largely obsolete. Speakers should note that calling an adult man 'boy' can be condescending, and it carries a particularly painful history when directed at Black men in the United States. Its derivatives include boyish, describing youthful charm or behaviour, and boyhood, the period of being a boy. Simple, ancient, and endlessly flexible, boy remains one of the most fundamental words for talking about growing up male.
A male child or young man.
"The boys played football in the park until dusk."
Used to express surprise, emphasis, or enthusiasm.
"Boy, that was a close call!"
Regular plural formed by adding -s.
"The boys arrived early for practice."
For centuries 'boy' could mean a servant of any age — even a grown man was called a boy if he served someone else, which is why the phrase 'my boy' once carried more hierarchy than affection.

Etymology of boy
The word boy first appears in Middle English around the thirteenth century, with early senses including both 'male child' and 'servant'. Its ultimate origin is uncertain: scholars have proposed connections to Old French embuié ('fettered', hence bound as a servant), though this remains debated. The word has no widely accepted cognates in other Germanic languages, making its deeper history unusually murky for such a common word.
