Onomatopoeia is the imitation of natural sounds in word form. These words help us form mental pictures about the things, people, or places that are described.
Alliteration is when several words in a row begin with the same sound. [You may have some words in between alliterated words that don’t start with the same sound as long as they don’t interrupt the sound pattern.]
The snake slithers secretly across the sand.
Repetition is when one or more words are repeated to show urgency or importance.
Stop, stop, stop!!
