It means a little cold at first. As time changes, the word gets many different meanings. We can use “cool” when we talk about something wonderful or somebody looking smart. For example. When you see a beautiful and expensive car in the street, you can say, “It is cool.” You may think the popular singer Jay Chow is cool. You can also use the word to mean something new and surprising.
