How do I write an academic conclusion?My topic is Elizabethan drama and Greek drama?
An academic conclusion is about 5 - 7% of your whole essay, meaning it is not a very long part of your writing. It includes a statement of how you fulfilled the idea you specified in your thesis statement (you might call that your "bright idea"). You also need to state how you went about proving your thesis statement. An academic conclusion also states the limitations of the research or critics' analysis, etc., you used as evidence. Then you state suggestions or remedies for those limitations.
This may sound like a lot but it need not be. Here's a quick (and silly) hypothetical example. My thesis statement relevant to a literary analysis of the nursery rhyme "Humpty Dumpty" is that Humpty Dumpty fell off the wall as an act of insurgence against the King. CONCLUSION: Based on textual analysis of "Humpty Dumpty," it is clear that Humpty fell off the wall in order to draw the King's horses and men away from the castle in order for other rebellious Nursery Rhyme characters to overthrow the kingdom in a act of insurgence. Psychological analysis of Humpty Dumpty has hitherto been overlooked, but I suggest that a psychological examination of other Mother Goose Nursery Rhymes will reveal more of the rebelliousness shown by Humpty.
Not knowing what you have included in the rest of your essay makes it rather difficult to help you with a conclusion, but assuming that you wrote a comparison essay about the two drama genres, you should consider broadening your topic in the concluding paragraph. For example, you might discuss how even though the two types of drama possesses many difficulties, they also illuminate common traits in human nature. From there, you could discuss those common traits.
