Illustrative is a word that means to explain. You must have come across this term many times and it might get easy for you when such terms are explained using relevant pictures and videos. There is a tagline added under an image or topic which states “for illustrative purposes only”. This would mean that the topic is explained in detail to make it simpler. The same concept applies to illustrative essays. It helps to make the subject understand the concept in detail and ensure that the reader gets a complete idea of the matter. You can write an illustrative essay to give examples through about the subject to explain it better and let the readers decide the fate of the subject.
