What does the term 'prodigal' primarily describe?

The term 'prodigal' primarily describes wasteful behavior, especially with regard to spending resources or money. It originates from the story of the "Prodigal Son" in the Bible, where the son squanders his inheritance on extravagant living before experiencing a significant change of heart. This context highlights the idea of excessive or reckless spending, ultimately leading to a depletion of resources. In a broader sense, 'prodigal' can also refer to any behavior that is lavish or extravagant to the point of being irresponsible. This understanding of 'prodigal' aligns perfectly with the choice that identifies wasteful behavior as its primary descriptor.
