“Cool” can be used to expressing a temperature that is a little bit cold or feelings of interest in almost anything. Sometimes we maximized the meaning of “cool”. You can use it instead many other word such as “new” or “surprising”. Here’s an interesting story we can use to show the way the word is used. A teacher asked her students to write about the waterfall she had visited. On the one student’s paper was just one sentence, “It’s so cool.” Maybe he thought it was the best way to show how he saw and felt. The story shows lack of words. With “cool”, some people have no words to show the same meaning. Can you think of any expression made your life as colorfully as the word “cool” ?
