For better undersanding poetry we need to study the literary devices or literary terms!

For example, what is a paradox or an onomatopeia? 

ONOMATOPOEIA - the use of words which sound like what they mean.

HYPERBOLE - an exaggeration in the service of truth - an overstatement. :D 

We'll better understand these terms by studying these websites. Go!
