Opposite is like when you have a light and a dark. Light is what you see when the sun is out, and dark is what you see when it’s nighttime. They are completely different, just like day and night. When one is around, the other isn’t.
Think about a hot summer day and a cold winter day. Hot makes you want to wear shorts and play outside, while cold makes you want to wear a coat and drink hot chocolate. They are opposites because they make you feel very different.
Imagine a happy face and a sad face. When you’re happy, you smile and laugh. When you’re sad, you might frown or cry. These feelings are opposites because they are not the same at all.
Consider a big elephant and a tiny mouse. The elephant is huge and takes up a lot of space, while the mouse is small and can fit in your hand. They are opposites because one is very big, and the other is very small.
Opposite is about things being very different from each other, like a yes and a no. A yes means you agree, and a no means you don’t. They are opposites because they mean completely different things.
