An orphan (from the orphanós) is a child whose parents have died.
In common usage, only a child who has lost both parents due to death is called an orphan. When referring to animals, only the mother's condition is usually relevant (i.e. if the female parent has gone, the offspring is an orphan, regardless of the father's condition).
Various groups use different definitions to identify orphans. One legal definition used in the United States is a minor bereft through "death or disappearance of, abandonment or desertion by, or separation or loss from, both parents".
In the common use, an orphan does not have any surviving parent to care for them. However, the United Nations Children's Fund (UNICEF), Joint United Nations Programme on HIV and AIDS (UNAIDS), and other groups label any child who has lost one parent as an orphan. In this approach, a maternal orphan is a child whose mother has died, a paternal orphan is a child whose father has died, and a double orphan is a child/teen/infant who has lost both parents. This contrasts with the older use of half-orphan to describe children who had lost only one parent.
Orphans are relatively rare in developed countries, because most children can expect both of their parents to survive their childhood. Much higher numbers of orphans exist in war-torn nations such as Afghanistan.
