Onomatopoeia

Onomatopoeia is used to describe words that sound like the sound they are describing. For example, when you rattle a jar of dry beans ... the word 'rattle' describes the sound, and it makes the sound when you say the word. Similarly, a balloon will pop ... the word 'pop' makes the sound the balloon does.
