Assonance is a literary device where vowel sounds are repeated in nearby words, creating a musical effect. This repetition of vowel sounds, often followed by consonants, helps to create a sense of rhythm and flow in writing.
For example:
* "The rain in Spain falls mainly on the plain." (repetition of the "ai" sound)
* "The cat sat on the mat." (repetition of the "a" sound)
