definition of assonance
From Wikipedia, the free encyclopedia. Assonance is the repetition of vowel sounds to create internal rhyming within phrases or sentences, and together with alliteration and consonance serves as one of the building blocks of verse. Assonance does not have to be a rhyme; the identity of which depends merely on sequence of both vowel and consonant sounds. Assonance occurs more often in verse than in prose. It is used in (mainly modern) English-language poetry, and is particularly important in Old French, Spanish and the Celtic languages.
