Assonance is a literary device where vowel sounds are repeated in a line or phrase, creating a sense of unity or musicality. The consonants following the repeated vowel sounds can be different.
Here are some examples:
* "The cat sat on the mat." (The repeated vowel sound is "a")
* "Old King Cole was a merry old soul." (The repeated vowel sound is "o")
* "Hear the mellow wedding bells." (The repeated vowel sound is "e")
Assonance is often used in poetry, song lyrics, and prose to enhance the rhythm and sound of the language.
