Definition:
Assonance refers to repetition of sounds produced by vowels within a sentence or phrase. In this regard assonance can be understood to be a kind of alliteration. What sets it apart from alliterations is that it is the repetition of only vowel sounds. Assonance is the opposite of consonance, which implies repetitive usage of consonant sounds.
Example:
“A long song”. (Where the ‘o’ sound is repeated in the last two words of the sentence)
A slow blow
Thou still unravished bride of quietness
Thou foster child of silence and slow time
Wouldn’t
” silent night,lonely night “be one
Good examples
‘Egregious replete with these lesions’
The Negative One
Slipknot
Just thought this one was worth mentioning.
