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 prove an answer with steps or prove honesty through actions. The word comes from Latin probare, meaning “to test” or “to check”. So to prove originally meant testing something to see if it is true or good.
