Copyright is a law that protects original work, like books, music, art, and videos, so the person who created it has control over how it's used. This means others need permission to copy, share, or change it. However, there’s a rule called fair use that lets people use small parts of copyrighted work without permission for special reasons, like schoolwork, reporting news, or creating something new based on it, such as a review or parody. Fair use is limited, so it’s important to use only as much as you need and always respect the creator’s rights!
