An example would be, "Jane runs as fast as a cheetah." Jane is not a cheetah, but you're comparing her to one because she's fast while using the word "as."

An example would be, "Bill is an angel." I do not mean Bill has died and become an angel. Rather he is demonstrating angel like qualities.

A well-known idiom could be, "This lesson is a piece of cake." Sadly, this does not mean we get to eat cake for English class today. Rather, it is a known phrase that means this is super easy.

Human qualities can include actions, feelings, or thoughts. An example would be, "The leaves danced in the wind." Leaves cannot do ballet, tap, dubstep, etc. They are simply blowing with the wind.

What does a cow say? "Moo!" That is an example of onomatopoeia including bang, pow, oink, slap, squish, and countless others.

Do you like tongue twisters? Alliteration is for you! "Peter Piper picked a peck of pickled peppers." Each main word begins with the "p" sound.
