whats alliteration and assonance?

Alliteration is the repetition of initial sounds in neighboring words.

Example:

In cliches: sweet smell of success, a dime a dozen, bigger and better, jump for joy

Wordsworth: And sings a solitary song That whistles in the wind.

Assonance is the repetition of vowel sounds but not consonant sounds as in consonance.

Example:

fleet feet sweep by sleeping geeks.

An alliteration is the repeating consonant sound.

Mary Munch On Muffins would be an alliteration.

An assonance is the repeating of the vowel sound.

I ate a gate so I was late would be an assonance.

Mary Munch on Muffins is alliteration and the gate eating one is assonance

Alliteration is the repeated occurrence of a consonant sound at the beginning of several words in the same phrase.

example: mary munches on muffins

Assonance is repetition of vowel sounds to create internal rhyming within phrases or sentences.

example: mellow wedding bells
