, the author of the illustration essay should try to carefully select the words that can best help the reader in creating a mental picture of what is being illustrated. The choice of illustrative words for the illustrative essay should put into account the objective of the writing which is to pass a message that the reader can effectively use to understand the concept illustrated within the illustration essay. At times the choice of one illustration may not suffice in clearly showing the reader what you as a writer would like to pass across through the illustration essay. Therefore, at times it becomes prudent, and it is actually allowed for an author of an illustration essay to use more than one illustration to express his or her ideas. This may be especially important when writing any illustrative research paper that meant for different categories of readers.
