A ‘source’ is like the beginning of a story. Just like how every fairy tale starts with ‘Once upon a time,’ a source is where information or things come from. Imagine you have a big book full of stories. Each story has a special page at the start that tells you who wrote it and where it came from. That page is like the source because it tells you where the story began.
Think of a fountain in a park. The water that bubbles up from the ground and flows into the fountain is like a source. It’s the starting point where the water comes from before it moves to other places. Without the source, the fountain would be dry, and there wouldn’t be any water to see or play with.
Another way to think about a source is like a kitchen. When you bake cookies, you need ingredients like flour, sugar, and eggs. The store where you get these ingredients is the source. It’s the place you go to find everything you need to make something delicious. Without the source, you wouldn’t have the ingredients to bake your cookies.
