The term parallels "Anglophone" (English-speaker), and "Francophone", which designate people whose mother tongues are English and French, respectively.  Native speakers of aboriginal languages are generally not treated as allophones.

Besides the paternal bonds of a father to his children, the father may have a parental, legal, and social relationship with the child that carries with it certain rights and obligations.  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 infant, 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 mother's boyfriend is a man whose girlfriend has a son or daughter from a previous marriage or relationship.  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.
