When we talk about something being abnormal, it’s like when you see a rainbow in the sky, but instead of having all its colors, it only has one color, like just red. Usually, rainbows have many colors, so a rainbow with just one color is different from what we expect, and that’s what makes it abnormal. It’s not bad, just not what we usually see.
Imagine you have a box of crayons. If you open the box and find that all the crayons are shaped like triangles instead of the usual round shape, that’s something abnormal. Crayons are normally round, so triangle crayons are unusual, and that makes them abnormal.
Think of a birthday cake. Normally, birthday cakes have candles on top. But if you see a birthday cake with flowers instead of candles, that’s different from what we usually see on a birthday cake. It’s special and unique, but not what we expect, so it’s abnormal.
The word abnormal helps us describe things that are different from what we usually see or expect. It’s like a little surprise that makes us say, ‘That’s different!’
