I guess many would see expositions as “the essay-things that our English teachers demand over the weekend” or “number twenty-four on my list of things to study before EOYs” – and while these might hold some element of truth, I believe an exposition goes far deeper than that.
A skin-deep glance would make it seem like the purpose of an exposition is “to expose”, in other words stating that which is hidden and uncovering what lies below the surface of any topic. But in actuality, the word ‘exposition’ stems from the root meaning “to expound”, and thus a good exposition should not only inform but explain. It should also provide opinion and connection to larger concepts alongside mere fact, and give the reader a wholesome and concise view of the subject. In other words, it is an essay aimed towards simplifying and evidencing that which is difficult to understand, and making every outsider a connoisseur.
