A metaphor is a figure of speech that describes one thing as something else. It does NOT use like or as.
The Metaphor Family
My brother is a dragon.
My mom's a teddy bear.
I am a shaggy sheepdog
with a ton of tangled hair.
My father is a monkey.
He likes to make us laugh,
especially my sister,
who is a tall giraffe.
We are a busy family
with many things to do.
Our home is always happy,
but sometimes it's a zoo.
