Fair use is a legal doctrine that allows the use of copyrighted materials for certain purposes without the permission of the copyright owner. The four factors that determine fair use are: the purpose and character of the use; the nature of the copyrighted work; the amount and substantiality of the portion used; and the effect of the use on the potential market for or value of the copyrighted work. Fair use is not a right, but a defense to copyright infringement. It is important to consider fair use when using copyrighted materials for educational, research or criticism purposes.​

"Okay kiddos, fair use means sometimes you can use things that someone else made without asking their permission. But there are rules! You have to be using it for certain reasons like school work or talking about it. You can't use too much of it and it can't ruin the original work. You can't just use it because you want to, you gotta have a good reason. And if someone says you're using their stuff wrong, you can say 'but it's fair use!' to try and defend yourself. Just remember, it's important to be fair and not use other people's stuff in a bad way!"
