Which is not a simile? he runs like a deer. the baby is as cuddly as a kitten. i'm as hungry as a wolf. his nose is a button.

A simile is defined as a comparative term to compare two things using the terms "Like" or "as a".

With our definition above, let's see if we can eliminate some answer choices, if any.

"He runs like a deer."
This is a simile, as it uses "like" to compare two things, but we are looking for what's NOT a simile. This answer choice can be eliminated.

"The baby is as cuddly as a kitten."
This is a simile, as it uses "as a" to compare two things, but we are looking for what's NOT a simile. This answer choice can be eliminated.

"I'm as hungry as a wolf."
This is also a simile, as it uses "as a" to compare two things, but we are still looking for what's NOT a simile. This answer choice can also be eliminated.

"His nose is a button."
This is NOT a simile, as it does not compare two things with the terms "like" or "as a".

Your correct answer is:

"His nose is a button."

I hope this helps!
