Orphans

An orphan is a child whose parents are dead or have permanently abandoned the child. 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. If she has gone, the offspring is an orphan, regardless of the father's condition.

Those who have reached adulthood before their parents died are normally not called orphans; the term is generally reserved for children whose parents have died while they are too young to support themselves.
