Explanation:
Metaphor is the use of “is” and “was”.
And also Simile is the use of “as” and “like”
So in this sentence;
“Her hair was so blond it looked like gold”, the sentence can either be a Simile or a Metaphor.
“My mind was going a million miles a minute”
The sentence can either be a metaphor because of the use of “was” and it can also be an exaggeration
