Explanation: A metaphor can be simply defined as a figure of speech that compares actions or words that are not literally related but might share similar characteristics. It gives a hidden meaning or representation.
"The road to the mountains was a ribbon of moonlight",
The "road" and the "ribbons of moonlight" are literally unrelated because roads are neither ribbons nor ribbons of moonlight.
"Ribbons of moonlight" is only meant to give a hidden meaning or representation of the characteristic or nature of the road to the mountains.
