Orphans

An orphan (from the Greek) is a child permanently bereaved of his or her parents. In common usage, only a child (or the young of an animal) who has lost both parents is called an orphan. However, adults can also be referred to as orphans, or "adult orphans".

In certain animal species where the father typically abandons the mother and young at or prior to birth, the young will be called orphans when the mother dies regardless of the condition of the father.
