Is the sentence butterfly was as graceful a ballerina metaphor?

The sentence "Butterfly was as graceful as a ballerina" is indeed a metaphor. Here's why:

* Metaphor: A metaphor directly compares two unlike things without using words like "like" or "as." It implies a resemblance between the two.

* Comparison: The sentence compares the grace of a butterfly to the grace of a ballerina.

* Implied Similitude: While not explicitly stated, the sentence suggests that a butterfly shares the same qualities of gracefulness as a ballerina.

Therefore, the sentence is a metaphor because it directly compares the butterfly to a ballerina, implying a shared characteristic of grace.
