Metaphor

Metaphor is a comparison of two things with a similar quality by saying one object is the other. 

An example for a metaphor is the boy is a thorn in my side. The object is the boy. The comparison is the thorn. The meaning is that someone is very annoying

Another example for a metaphor is the girl has a heart of a lion. The object is the girl. The comparison is the heart. The meaning is that the boy is courageous

By using metaphors, people can describe things like food, feelings, sound, colour, and more. Metaphors identify a comparison.
