Meritorious describes something that deserves recognition, reward, or praise because of its quality or excellence. A meritorious performance in a piano recital means you played with real skill and effort that others should appreciate. A soldier might receive a medal for meritorious service after years of dedication and outstanding work.

When something is meritorious, it has genuine merit: it demonstrates true worth and excellence that earns recognition. A science project might be meritorious because it shows original thinking and careful research, standing out for its intellectual substance.

Teachers sometimes give meritorious awards to students who've shown exceptional effort or achievement. In legal contexts, a meritorious case is one that has real substance and legitimate grounds, built on solid evidence and sound reasoning. The word carries a sense of earned recognition: meritorious work stands out because of its actual quality, achieving something worth celebrating based on the real value of what you've done.
