Why Do Poets Use Assonance?

Poets use assonance as a device to enhance poetry and add a musical effect by introducing similar vowels followed by different end consonants. Assonance is similar to rhyme; however, rhyme differs from assonance in the fact that in rhyme, both the vowels and the consonants resemble each other.

An example of similar words where assonance is used is "lake" and "fate," while an example of rhyme is "lake" and "fake." Some poets that have used assonance in poetry include Emily Dickinson, Edgar Allan Poe, Algernon Charles Swinburne and Dylan Thomas. Lines of poetry where Emily Dickinson employs this literary device are: "The grass divides as with a comb, / A spotted shaft is seen, / And then it closes at your feet / And opens further on."
