When something is described as vigorous, it means it’s full of energy and liveliness. Think about a puppy that is always jumping around, wagging its tail, and playing with its toys. That puppy is showing vigorous behavior because it is very active and full of life.
Another way to think about vigorous is like when you are running around in the playground, your heart is beating fast, and you’re having lots of fun. You are being vigorous because you are using a lot of energy and moving around a lot.
Imagine a plant growing in the garden. If it is growing quickly with big, green leaves, it is growing vigorously. This means the plant is healthy and strong, using its energy to grow big and tall.
Vigorous can also be like when you are coloring a picture with bright colors and pressing the crayons hard on the paper. The colors are bold and lively, making your picture look exciting and full of life. That’s vigorous coloring because you are putting a lot of effort and energy into it.
