Son in the context of "Boy"

A child (pl. children) is a human being between the stages of birth and puberty, or between the developmental period of infancy and puberty. The term may also refer to an unborn human being. In English-speaking countries, the legal definition of child generally refers to a minor, in this case as a person younger than the local age of majority (there are exceptions such as, for example, the consume and purchase of alcoholic beverage even after said age of majority), regardless of their physical, mental and sexual development as biological adults. Children generally have fewer rights and responsibilities than adults. They are generally classed as unable to make serious decisions.

Child may also describe a relationship with a parent (such as sons and daughters of any age) or, metaphorically, an authority figure, or signify group membership in a clan, tribe, or religion; it can also signify being strongly affected by a specific time, place, or circumstance, as in "a child of nature" or "a child of the Sixties."

In biology, offspring are the young creation of living organisms, produced either by sexual or asexual reproduction. Collective offspring may be known as a brood or progeny. This can refer to a set of simultaneous offspring, such as the chicks hatched from one clutch of eggs, or to all offspring produced over time, as with the honeybee. Offspring can occur after mating, artificial insemination, or as a result of cloning.

Human offspring (descendants) are referred to as children; male children are sons and female children are daughters (see Kinship).

In genealogy, a cadet is a younger son, as opposed to the firstborn heir.

A daughter is a female offspring; a girl or a woman in relation to her parents. Daughterhood is the state, condition or quality of being someone's daughter. The male counterpart is a son. Analogously the name is used in several areas to show relations between groups or elements. From biological perspective, a daughter is a first degree relative. The word daughter also has several other connotations attached to it, one of these being used in reference to a female descendant or consanguinity. It can also be used as a term of endearment coming from an elder.

In patriarchal societies, daughters often have different or lesser familial rights than sons. A family may prefer to have sons rather than daughters and subject daughters to female infanticide. In some societies, it is the custom for a daughter to be 'sold' to her husband, who must pay a bride price. The reverse of this custom, where the parents pay the husband a sum of money to compensate for the financial burden of the woman and is known as a dowry. The payment of a dowry can be found in societies where women do not labour outside the home.

Ælfweard (/ˈælfwɔːrd/; c. 902  – c. August 924) was the second son of Edward the Elder, the eldest born to his second wife Ælfflæd.

A firstborn (also known as an eldest child or sometimes firstling) is the first child born to in the birth order of a couple through childbirth. Historically, the role of the firstborn child has been socially significant, particularly for a firstborn son in patriarchal societies. In law, many systems have incorporated the concept of primogeniture, wherein the firstborn child inherits their parent's property. The firstborn in Judaism, the bechor, is also accorded a special position.
