The word "valid" means that something is true or acceptable. For example, if you say "I have a valid driver's license," it means that your license is legally accepted and you are allowed to drive. Or, if someone says "This argument is not valid," it means that the argument is not well-supported with evidence or does not make sense. You can use the word "valid" in many different situations, such as when talking about documents, proofs, arguments, or opinions.
