Culture is like a big box of different things that people create, like music, art, stories, and movies. Copyright means that the person who created something has the right to say how it can be used or shared by others.
Imagine you make a cool drawing of your favorite animal. You have copyright over that drawing, which means nobody else can copy it or use it without asking you first.
Sometimes, people use parts of other people's creations to make something new. For example, a musician might use a sample from an old song to make a remix. This is called "borrowing" or "remixing" and is a part of culture.
But sometimes, people take other people's creations and use them without asking or without giving them credit. This is called "stealing" and is not okay. Copyright laws help protect people from having their creations stolen.
So, culture and copyright can be related because people make and share things as a part of culture, and copyright protects them from having their creations taken without permission.
