Hyperbole

Hyperbole

          a way of speaking or writing that makes someone or something sound bigger, better, more, etc. than they are: The ​blurb on the back of the ​book  was ​full of the ​usual hyperbole - "​enthralling", "​fascinating", and so on.

           We use hyperbole /haɪˈpɜ:bəlɪ/ to exaggerate. We sometimes do this to emphasise something, to add humour or to gain attention. When we use hype rbole, we often make statements which are obviously untrue
