Being sparing is the act of using something in a limited or conservative manner. The opposite of being sparing would be to use something excessively, extravagantly or lavishly. Some antonyms for being sparing include prodigal, wasteful, excessive, immoderate, profuse, and luxurious. When someone is not being sparing, they are often indulging themselves or being extravagant with their resources. In contrast, when someone is being sparing, they are demonstrating self-control and are conscious of their limitations. It is important to strike a balance between the two extremes in order to maintain a sustainable lifestyle while still enjoying life's pleasures.
