Metaphor

Metaphor is a type of analogy, but where analogy is identifying two things as similar, a metaphor claims a comparison where there may not be one. It is then up to the listener to create meaning out of this comparison.

For example “ that sound goes through me like nails down a blackboard”. The sound may be very different to the nails on the blackboard, but create a similar sensation or emotion.

Simile

Finally, a less important but common metaphor. It takes the idea of comparing two unrelated subjects to create meaning at a deeper level, it is figure of speech where two unlike subjects are explicitly compared. They tend to be more lyrical and less literal.
