Similes, also known as indirect comparisons, are similar in construction to metaphors, but they imply a different meaning. Like metaphors, two unrelated objects are being compared to each other. Unlike a metaphor, the comparison relies on the words “like” or “as.”

Example of simile: This tree is like the god of the forest.

OR: This tree acts as the god of the forest.

What is the Difference Between a Simile and a Metaphor?

The obvious difference between these two common literary devices is that a simile uses “like” or “as,” whereas a metaphor never uses these comparison words.

Additionally, in reference to the above examples, the insertion of “like” or “as” creates a degree of separation between both elements of the device. In a simile, the reader understands that, although the tree is certainly large, it isn’t large enough to be a god; the tree’s “godhood” is simply a description, not a relevant piece of information to the poem or story.

Simply put, metaphors are better to use as a central device within the poem/story, encompassing the core of what you are trying to say. Similes are better as a supporting device.

Does that mean metaphors are better than similes? Absolutely not. Consider Louise Gluck’s poem “The Past.” Gluck uses both a simile and a metaphor to describe the sound of the wind: it is like shadows moving, but is her mother’s voice. Both devices are equally haunting, and ending the poem on the mother’s voice tells us the central emotion of the poem.

Simile and Metaphor Writing Exercise: Tenors and Vehicles

Most metaphors and similes have two parts: the tenor and the vehicle. The tenor refers to the subject being described, and the vehicle refers to the image that describes the tenor.

So, in the metaphor “the tree is a god of the forest,” the tenor is the tree and the vehicle is “god of the forest.”

To practice writing metaphors and similes, let’s create some literary device lists. Grab a sheet of paper and write down two lists. In the first list, write down “concept words”—words that cannot be physically touched. Love, hate, peace, war, happiness, and anger are all concepts because they can all be described but are not physical objects in themselves.

In the second list, write down only concrete objects—trees, clouds, the moon, Jupiter, New York brownstones, uncut sapphires, etc.

Your concepts are your tenors, and your concrete objects are your vehicles. Now, randomly draw one between each tenor and each vehicle, then write an explanation for your metaphor/simile. You might write, say:

“Peace, like an uncut sapphire, gleams with labor.”

Have fun, write interesting literary devices, and try to incorporate them into a future poem or story!
