Simile, metaphor, hyperbole, and personification are all figures of speech.
Simile compares one thing with another thing that is of a different kind. It uses “like” or “as” to compare.
Ex: She is as blithe as a lark. Your words are like balm to my aching heart.
Metaphor is similar to simile, except that it does not make use of words “like” or “as” to compare.
The living room was a war zone after the boys left. The new leader rules with an iron hand.
Hyperbole is an exaggerated statement or claim which is not meant to be taken literally.
Her dress costs a fortune. He was burning with rage.
Personification attributes human character to something that is nonhuman.
Ex: The trees lift their arms to heaven. The earth devoured the houses as the earthquake shook the entire city.
