Explanation
To prove means to show that something is true by giving facts, evidence, or clear results. When you prove something, you remove doubt and help others believe it. For example, you may prove a math answer by showing the steps, or prove your honesty through your actions. The word is related to the root prob, which means “to test” or “to check whether something is good or true”. In earlier times, people would test or examine something carefully to see if it was correct or trustworthy. From this idea, the word developed the modern meaning of showing through evidence or testing that something is true.
