Simile and Metaphor

Both similes and metaphors draw comparisons between two or more things; however, there are some key differences between them. Similes always use the word like or the word as to make the comparison. Metaphors do not use the word like or as. Consequently, metaphors can be more implicit and harder to identify. 

Here’s an example to help you understand: 

This is an example of a metaphor. The speaker is comparing her eyes to heaven, but this is not done explicitly. The comparison is implied.

Here is the same example but turned into a simile: 

In this example the comparison is more explicit. It is easier to identify that the speaker is making a comparison.
