Assonance
Assonance is the repetition of similar vowel sounds in nearby words, creating internal rhyme and musicality.

How assonance works
Assonance repeats vowel sounds within a run of words, often in stressed syllables, while the surrounding consonants vary. In "a host of golden daffodils", the repeated long "o" links the words by sound. Because it is subtler than end rhyme, assonance can colour a line’s mood without drawing obvious attention — long, open vowels can feel slow and sonorous, while short, high vowels can feel quick and bright. It is a matter of sound, not letters, so "rough" and "cuff" share assonance even though their spelling differs.
Assonance, consonance and alliteration
Assonance is one of three closely related sound devices. Assonance repeats vowel sounds ("fleet feet sweep"). Consonance repeats consonant sounds, often at the ends of words ("the lumpy, bumpy road"). Alliteration repeats the initial consonant sound of nearby words ("wild and woolly"). The simplest way to tell them apart is to identify which sounds recur: vowels point to assonance, consonants anywhere to consonance, and word-initial consonants to alliteration. Poets often weave all three together to build a passage’s texture.
Why writers use assonance
Assonance gives verse and prose a musical undercurrent that binds words and reinforces feeling. It can create internal rhyme within a line, smoothing the flow without the finality of an end rhyme, and it helps establish tone through the character of the chosen vowels. Songwriters rely on it heavily, since matching vowel sounds carry well when sung. In prose, assonance lends memorable phrases a pleasing echo. As with other sound devices, its power lies in being felt more than noticed, shaping the reader’s experience below the level of conscious attention.

Common misconceptions
What people often get wrong
Often heard: Assonance and consonance are the same device.
Actually: They differ by which sounds repeat. Assonance repeats vowel sounds, while consonance repeats consonant sounds. Both create echo and rhythm, but they target different parts of a word’s sound.
Often heard: Assonance must occur at the start of words.
Actually: Repetition at the start of words is alliteration. Assonance repeats vowel sounds anywhere within nearby words, most often in the stressed syllables rather than necessarily at the beginning.
Often heard: Assonance is the same as rhyme.
Actually: Full rhyme matches both the vowel and the following consonant sounds ("cat"/"hat"). Assonance matches only the vowel sounds, so it produces a looser, internal echo rather than a complete rhyme.
