Orphan

An orphan (from the Greek ορφανός) is a person (typically a child), who has lost both parents, often through death. One legal definition used in the USA is someone bereft through "death or disappearance of, abandonment or desertion by, or separation or loss from, both parents".[1] Common usage limits the term to children, (or the young of animals) who have lost both parents. On this basis half-orphans are those with one surviving parent.

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