The word deep can be like a big swimming pool. Imagine when you stand at the edge, you can see the bottom in the shallow part, but as you move to the middle, it gets harder to see. That’s because it’s deep. It means there is a lot of water from the top to the bottom, and you can’t see all the way through.
Think of a deep forest. When you look at the trees at the edge, you can see sunlight and paths. But when you walk further inside, it becomes darker and quieter. The trees are tall and close together, making it hard to see what’s far away. This is like being deep in the forest, where you are surrounded by many trees.
Consider a deep thought. When you have a simple idea, it’s like a small puddle. But when you think about something very hard, like why the sky is blue, your thoughts go deeper, like a big ocean. It means you are thinking a lot and trying to understand something very well. Deep thoughts take you on an adventure inside your mind.
