A more thorough explanation: In legal terms, a “waif” refers to a child or young person who is abandoned or neglected, often without any known family or guardian. The term may also be used to describe property that has been abandoned and is unclaimed.
Example: The court appointed a guardian ad litem to represent the interests of the waif in the custody proceedings.
