Explanation
A principle is a basic rule, belief, or idea that guides how a person thinks or behaves. It helps someone decide what is right or wrong. People often follow principles to stay honest, fair, or responsible. For example, telling the truth or respecting others can be personal principles. Principles can also be general rules that explain how something works, like scientific or mathematical principles. They act like foundations that support actions and decisions in everyday life.
