Why are literary elements important?
I think literature that contains these elements requires a very clever mind to write. It’s easy to spell out everything for your reader, but to employ symbolism is almost an art. I view words as clay, and a clever person can craft and mold them endlessly. For your essay, you could use the theme of how “Classic authors play with the English language endlessly to create a new and original work of art” or something along those lines.
