What is the meaning of 'prodigal'?

The term 'prodigal' primarily means wasteful, particularly in the context of spending resources extravagantly or carelessly. It describes someone who uses their money or possessions in a way that is reckless, often leading to negative consequences. This meaning is rooted in the historical context of the term, famously illustrated in the biblical parable of the Prodigal Son, who squanders his inheritance on lavish living. While the word can carry a connotation of generosity in the sense that a prodigal person may give freely or be abundant in their actions, this does not overshadow the primary implication of wastefulness.

The other options, while related to different aspects of behavior, do not encapsulate the essence of 'prodigal' as accurately as wasteful does. Sensible and thrifless imply a more prudent and economical approach, which directly contrasts with the extravagant nature of being prodigal. Generous, while it can describe giving freely, does not specifically relate to wastefulness, and therefore, it does not capture the term's main meaning as effectively as wasteful does.
