Metaphor

 A metaphor is a figure of speech that identifies something as being the same as some unrelated thing for rhetorical effect, thus highlighting the similarities between the two. While a simile compares two items, a metaphor directly equates them and does not use "like" or "as" as does a simile.

Example:

All the world's a stage,

And all the men and women

merely players;

They have their exits and

their entrances[...]

William Shakespeare,

As You Like It

n  During the night the forest was a dark, frightening battlefield.

n  A heart of stone

n  He has the heart of a lion.

n  You are the sun in my sky.

n  You are the light in my life.
