The lines with assonance are:
- The squat pen rests; snug as a gun.
- Nicking and slicing neatly, heaving sods.
Assonance is one of the most common rhetorical devices, used most frequently in poetry. It is the repetition of vowels in adjacent words or phrases, emphasizing the melody of the language. The vowels don't have to be identical.
The difference of the poems of Walt Whitman
and Emily Dickinson is that Whitman uses
personification, whereas Dickinson avoids
figurative language. Whitman incorporates
transcendentalism and realism in his works. On the other hand, Dickinson's poems talks about death and immortality.
Hope that helps! Have a good day :)
