Last week we looked at the two main types of topic sentence. They both have different functions, so in this post we’ll examine how and when to use each type of topic sentence to create a balanced essay.
Technique-based topic sentences summarise the evidence you will present (literary devices in English Literature essays; quotations, citations, statistics, theories and other types of evidence in essays for other disciplines). Thematic topic sentences are the distilled interpretations or implications of that evidence. Technique-based topic sentences are useful for linking paragraphs as they summarise the bulk of the essay and make smooth transitions for readers because they are generally easy to understand. Thematic-based topic sentences can also be used to link paragraphs. However, because they communicate deeper thoughts, they can take a little longer to absorb. This is often advantageous, because it further breaks up your essay, and it increases the likelihood of your sophisticated thoughts being understood.
It’s the thought that counts. The closing thematic topic sentence is there to sum up the argument and present the thematic implications in a compelling and thought-provoking manner. It could be as simple as “Time destroys.” I like that short sentence. (We’ll discuss sentence types and how to deploy them effectively in a future post). I’d already explained how the imagery in the poem “Ozymandias” conveyed this thematic message, so that sentence was fine on its own. Pauses can be powerful. Can you see how ending a paragraph with that punchy topic sentence will prompt the reader to reflect on the message?
Have another look at the post on how to order paragraphs, but this time read the examples with a different focus: to hone your understanding of topic sentences. Do you see how they hold each paragraph together, while linking the separate paragraphs in order; guiding the reader through both technical and thematic subtleties?
Notice that the thematic topic sentences often work well as closing topic sentences, because the final sentence will linger in the reader’s mind for a while, before they move on to the next paragraph. Thus, ending topic sentences are a great place to communicate important thematic ideas. They’re also a great place to answer the question explicitly, so the reader feels that reading the preceding evidence was relevant and worth their time.
However, engaging with thematic concepts is especially important if you want to get top marks, so thematic topic sentences can be used at the start of a paragraph too. Sometimes you might feel your thematic repetition won’t add value through new layers of meaning, though. In these situations – and also when it simply reads better if you relate evidence to previous paragraphs – technique-based topic sentences are great as the first topic sentence of a paragraph.
In general, technique-based topic sentences make your essay flow; while thematic topic sentences may cause the reader to pause while you go deeper (and also answer the essay question). Both effects can be useful; there’s a time and place for everything – balance the two types of topic sentence. Now you know which tool you can use to get the effect you want in each situation.
