Description

Imagine a slowly deflating balloon—that's a decrease in action! It means something is getting smaller, less numerous, or lower in value. You might see a decrease in temperature as winter approaches, or a decrease in sales if a product isn't popular. Sometimes it's subtle, like a slight decrease in your energy levels after lunch, and sometimes it's dramatic, like a significant decrease in the size of the rainforest due to deforestation.

Decrease can be used for all sorts of things: numbers, amounts, intensity, even feelings! If you try to decrease your sugar intake, you're trying to eat less of it. A doctor might tell you to decrease your stress levels. And if the stock market experiences a decrease, investors get worried. It's about moving downward in some way.
