Cool means something is really good or impressive. It started because scientists used it to describe things that worked well, like a cool machine. Now, we use it for anything awesome!
Examples
- A kid says, 'That ice cream is cool!' because it’s really good.
- Your friend says, 'You did a cool job!' when you finish your homework quickly.
- Mom says, 'This soup is cool!' after tasting it and liking it.
