In what way should I analyse form, structure, and language in my essay?

The most sophisticated way of making sure you integrate form, structure, and language into your essay is to synthesise them. As opposed to writing a paragraph on each element (which can certainly be useful every so often!), try to find ways in which they are related and how there might be a 'cause and effect' relation between two or three of them. Often, form can seem the most arbitrary element or the most difficult to discuss; however, if you aim to find a way in which the form of a text has an impact on, or determines, the way it is structured or written, this can provide a strong introduction to a more detailed structural or linguistic analysis. For example, the form of a letter determines the address of the writing (direct, informal) or the form of a poem affects structural elements such as syntax and visual presentation. Another interesting way to find original interpretations of the three elements and synthesise them is to consider readership and analyse how the components work to create a specific impression on the reader; for instance, the form of a novel may allow the writer to use heavy description which, in turn, aligns the reader with the protagonist and encourages sympathy with them.
