Prudentia is a big word for a smart way of thinking. It means that you make good choices because you think carefully about what might happen in the future.
For example, imagine you have some money and you want to buy a toy. Prudentia would mean that you don't just run and spend all your money on the first toy you see. Instead, you think about what you might need that money for in the future, like buying food or clothes.
Prudentia is like having a superhero power that helps you make good choices by imagining what might happen later, and planning for it. It's like being smart and thinking ahead, just like a grown-up!
