I would suggest learning the PEEL structure. PEEL stands for Point, Evidence, Explain, Link. When answering a question in an exam or in coursework, write the word PEEL on your planning page, and then structure your paragraphs from there. So, we start with 'Point: Your paragraphs should start with a short and to-the-point topic sentence, that enunciates what point you will be exploring in this paragraph (each paragraph should only explore one point). Then, we move onto 'Evidence': You will want to use a quotation from the text that is going to support your point in the topic sentence. For example, if your point is that potatoes are a key symbol in Seamus Heaney's poetry, you may then want to use a specific quotation from 'Digging', such as "To scatter new potatoes that we picked", or state that the repetition of the word "potatoes" within the poem is evidence. Then you will need to 'Explain' why that quotation proves your point. For instance, the repetition of "potatoes" makes them a recurring symbol, which shows that Heaney is concerned with the topic of potatoes. Your 'Explanation' should also include your 'WHY'. Explain why Heaney is concerned with potatoes. Finally, you will 'Link' back to the essay or exam question. For example, you will say that Heaney's use of potato symbolism shows that he is a nature poet. This is the best way to structure the paragraphs within the main body of your argument. However, there are different methods for your introduction and conclusion.
