A hyperbole is a huge exaggeration, for example the lake seemed endless, the tree reached the moon. In the song “A Year Without Rain” by Selena Gomez, the first hyperbole in the song is “I’ve been wondering in the desert for a thousand days”. This a huge exaggeration because, you could not wander the desert for a thousand days, just impossible, and the other hyperbole, is ” A day without you is like a year without rain”, this is also a huge exaggeration because it is impossible to have a year without rain. I thought th hyperboles helped emphasize how she was felling without her man. If you would like to hear this song just follow the link bellow.
