Poetry that is meant to be read out loud requires the use of onomatopoeia. For instance, if you are writing a piece of poetry that is aimed at describing the sounds made by a bell, you will need to use onomatopoeia. This way you will be able to use fewer words and convey your message to the reader effectively.
Onomatopoeia should be used while writing comics and graphic novels. This will help the writer save space as well as words because comics and graphic novels often need to be precise. For instance, if you are writing a graphic novel and plan to show that the person being hit is saying ‘He hit me!’ you can use the onomatopoeia ‘POW’. Apart from using fewer words, you will be able to give the reader a feel of the sound produced when someone or something is hit.
Apart from poetry and novels, onomatopoeia should be used while writing songs. Consider using syllables as an alternative to words in order to represent the notes being sung. For instance, use onomatopoeia such as do, re, mi, fa, so, la, ti and do.
Furthermore, onomatopoeia should be used while writing prose. For instance, you can make use of onomatopoeia in order to describe how an idea came to the mind of a character about whom you are writing in the prose. In ordinary English, you will have to use a proper phrase. However, using onomatopoeia, you can effectively save all those words.
