A metaphor asserts that one thing is another thing, even though the two things are not literally the same. Unlike simile, which uses “like” or “as” to make a comparison, a metaphor creates a direct relationship between the two things being compared.
Examples of metaphor:
“The world is a stage, and we are all merely players.” – William Shakespeare
“The road was a ribbon of moonlight over the purple moor.” – Alfred Noyes
“My life is a desert, barren and unyielding.” – anonymous
“The river was a giant serpent winding through the valley.” – Paulo Coelho
“The stars were a flock of birds taking flight.” – Stephenie Meyer
