Father

A father is the male parent of a (human) child. Besides the paternal bonds of a father to his children, the father has a parental social and legal relationship with the child that carries with it certain rights and obligations, although this varies between jurisdictions. An adoptive father is a male who has become the child's parent through the legal process of adoption. A biological father is the male genetic contributor to the creation of the baby, through sexual intercourse or sperm donation. A biological father may have legal obligations to a child not raised by him, such as an obligation of monetary support. A putative father is a man whose biological relationship to a child is alleged but has not been established. A stepfather is a male who is the husband of a child's mother and they may form a family unit, but who generally does not have the legal rights and responsibilities of a parent in relation to the child.

The adjective "paternal" refers to a father and comparatively to "maternal" for a mother. The verb "to father" means to procreate or to sire a child from which also derives the noun "fathering". Biological fathers determine the sex of their child through a sperm cell which either contains an X chromosome (female), or Y chromosome (male). Related terms of endearment are dad (dada, daddy), papa/pappa, papasita, (pa, pap) and pop. A male role-model that children can look up to is sometimes referred to as a father-figure.
