The most Powerful use of fig. lang

I think that the most powerful fig. lang is an exaggeration. An exaggeartion can be jusr about anything. For Example: She flew to school. We know people can really fly to school. What they ,mean is she ran to school really fast. An exaggeration could be (her screaming was like a hurricane) Thats an exageration. She probably screamed so loud that it was like a huuricane because Hurreicanes are loud.
