True , a metaphor compares two things without using like or as.
Explanation
Metaphors are used in the comparison of two things.
However, the differences among smiles and metaphors are that metaphors do not use words such as like or as in its comparison.
The comparison, therefore, is evidence that the stated thing is not related.
Metaphors have a metaphysical nature by comparing two entirely unrelated things.
Ultimately, it is easier to confuse between the two because of their character and use in a sentence, and they are both used for comparing items.
