What is the difference between a metaphor and a simile? Describe the effects of both.

A metaphor is a figurative language technique which describes an object, action or person by directly comparing it it to something else. Often the comparison creates a mood within the text that reflects the tone that they are trying to create. For example, 'his eyes were big blue pools'.  It may provide clarity for the reader or create a point of comparison that the reader can use to deepen their understanding of the text. A simile is similar to a metaphor as they are both used to create comparisons. However, a simile creates a comparison, often by using the words 'like' or 'as'. For example, 'his eyes were as big as big blue pools', or 'his eyes were like big blue pools'.  The effect of a simile is to create an interesting link or connection in a reader's mind.
