Question

What is the difference between a smile and a metaphor

Answer 1

No problem! Lemme explain :D
Okie so it's spelled, "simile", and often thought as "smile" xD
But so a simile is when you compare two things using the words "like" or "as". A metaphor is when you compare two things WITHOUT using "like" or "as".
Example;
Simile: "You are AS beautiful AS the northern lights."
Metaphor: "You dazzled the crowd because you are our shooting star."
See? c:

Answer 2

I'll start you off with some examples:
Simile: "Her eyes were like small galaxies, enchanting in themselves"
Metaphor: "Her eyes were small galaxies, enchanting in themselves"
See the difference?
All similes are metaphors, but not all metaphors are similes. Like that rectangle thing. A metaphor is a comparison, and a simile is a type of metaphor that uses "like" or "as" to compare things.
