Assonance
Repeated vowel sounds in nearby words, binding a phrase together without rhyming it.
Assonance is the repetition of vowel sounds in words that are close together but do not rhyme, because their surrounding consonants differ: 'the light of the fire is a sight'. It works on the ear rather than the eye — spelling is irrelevant, sound is everything, so 'crumbling thunder' counts and 'though through' does not.
The device does two jobs. It slows and unifies a phrase, making it feel deliberate and finished, and it gives memory something to hold. A great many surviving proverbs and slogans are assonant, which is not coincidence: sound-patterned phrases survive oral transmission better than flat ones.
Assonance pairs naturally with consonance (repeated consonant sounds) and alliteration (repeated initial sounds). Writers rarely use one alone; what reads as 'a good line' is usually two or three of these working under the surface at once.
Common mistake: forcing the vowel and distorting the sense. Assonance is a finishing move, applied when choosing between words that both say the right thing — never a reason to say the wrong thing beautifully.
