Assonance

Assonance is the repetition of the same vowel sound within a group of words. In the passage the long /e/ sound is repeated in the words sleep, sweet, and dream. Alliteration is the repetition of the same sound at the beginning of a group of words. An example would be Peter Piper picked a peck of pickled peppers. Onomatopoeia is a word that means the same as it sounds. A few examples of onomatopoeia are bang, slap, swish and drip. Rhyme is when two or more words have the same end sound like hop and pop.
