Why Long Sentences Are a Bigger Problem Than They Look
Long and complicated sentences are among the most persistent writing problems in Malaysian postgraduate theses. Students often write them because they are trying to include multiple nuances, qualifications, and evidential references in a single statement — and because long, dense sentences can feel academic and thorough. The reality experienced by the reader is very different. A sentence that runs to sixty or seventy words, with three embedded clauses, two pairs of commas, and a citation in the middle, forces the reader to do significant cognitive work before the main point can be extracted. By the time the sentence ends, both the main point and the supporting nuances may be equally unclear.
Fixing long sentences in your thesis does not mean writing short sentences throughout — variety in sentence length is a feature of good academic writing. It means ensuring that long sentences are genuinely earning their length by containing ideas too complex to separate, rather than being long because multiple ideas were combined without considering whether they could be more clearly expressed in shorter, more focused units.
How to Identify Problem Sentences During Proofreading
The most reliable method for identifying problematic long sentences during proofreading is reading your thesis aloud. Sentences that are too long to read in a single breath without losing the grammatical thread are almost always too long for a reader to process comfortably in a single reading. If you find yourself having to pause mid-sentence to remember where the main clause is, your reader will have the same experience.
You can also use the readability statistics feature in Microsoft Word. Go to File > Options > Proofing and check the box for “Show readability statistics.” After running a spelling check, Word will display average sentence length and the Flesch Reading Ease score for the document or selection. For academic writing, average sentence length of 20 to 25 words is a reasonable target. Sections where average sentence length consistently exceeds 30 to 35 words are likely to feel dense and difficult to read.
A targeted search approach is also useful: search for sentences containing more than one “which” or “that” clause, or more than two commas outside of a list structure. These are strong indicators of sentences that have grown beyond what readers can process comfortably in a single reading.
The Three Most Common Causes of Overlong Sentences
Understanding the structural causes of long sentences in Malaysian theses helps you fix them more efficiently during proofreading. The first and most common cause is stacked relative clauses — attaching multiple “which” or “that” clauses to a single main clause. “The data, which was collected from participants who were selected using purposive sampling, which allowed for depth rather than breadth, which is particularly important in qualitative research, revealed three main themes.” This sentence has three relative clauses and is significantly harder to parse than the same ideas expressed as two sentences: “Data was collected from participants selected through purposive sampling, an approach prioritising depth over breadth — particularly important in qualitative research. The data revealed three main themes.”
The second cause is excessive parenthetical qualification — inserting too many qualifications and hedges within a single sentence rather than allowing each qualification its own sentence. The third cause is trying to combine a finding and its interpretation in the same sentence when the two ideas would be clearer as separate sentences. All three problems are fixed by the same solution: identify where one idea ends and another begins, and place each idea in its own sentence or clause, joined only where the connection genuinely requires it.
Techniques for Breaking Down Long Sentences
Several practical techniques help when fixing long sentences in thesis writing during proofreading. The simplest is the full stop strategy: find the main clause of the sentence and end it with a full stop. Start a new sentence with the supporting information. “The researcher conducted semi-structured interviews, which were audio-recorded with participant consent and later transcribed verbatim, ensuring that all nuances of participant responses were captured” becomes two sentences: “The researcher conducted semi-structured interviews, audio-recorded with participant consent. All interviews were transcribed verbatim to capture nuances in participant responses.” Two sentences, same information, much more readable.
The semicolon strategy is useful when two ideas are closely related and of roughly equal grammatical weight: join them with a semicolon rather than embedding one within the other. The colon strategy works when the second part of the sentence explains or elaborates the first: use a colon to signal this relationship and keep both parts shorter and cleaner. Practising these restructuring techniques on your own most complex sentences develops an instinct for sentence architecture that improves your writing beyond the current thesis.
Maintaining Appropriate Complexity for Academic Writing
A legitimate concern when fixing long sentences in thesis writing is that simplifying sentence structure will make writing sound informal or insufficiently sophisticated. This concern is understandable but reflects a misunderstanding of what sophisticated academic writing actually looks like. The most respected scholarly writing in any discipline is precise and clear rather than impenetrably dense. A sentence that is easy to understand on first reading demonstrates greater mastery of the material than one that requires three readings to parse — because clear expression requires deeper understanding than vague complexity.
The goal when fixing long sentences in your thesis is not simplicity for its own sake. It is ensuring that every sentence’s length reflects the genuine complexity of its content, not the writer’s uncertainty about how to separate ideas efficiently. A thesis where sentences are appropriately varied — some longer where genuine complexity requires it, most shorter where clarity is possible — demonstrates exactly the kind of stylistic control and intellectual clarity that examiners and journal reviewers recognise as the mark of a mature academic writer.
