Why Language Rules Matter in Academic Writing
Academic writing is not just about sharing thoughts—it’s about doing it in a clear, correct, and confident way. Many students in the UK often lose marks because they break small language rules. These rules might look simple, but they have a big impact.
At Dissertationist.co.uk, we help university students across the UK write high-scoring dissertations and essays. In this guide, we’re not offering vague advice. We’ll give you 7 solid, easy-to-follow language rules for students that make your writing sharper, clearer, and more academic.
Want to write essays that sound professional, meet your university’s standards, and make your ideas stand out? Let’s begin.
1. Master Grammar in Academic Writing
If your grammar is weak, your message becomes unclear—even if your ideas are strong. Good grammar gives your writing flow and structure. It builds trust with your professor and lets your argument shine.
Focus Areas:
- Subject–verb agreement
Incorrect: The theories discussed in the class were useful.
Correct: The theories discussed in the class were useful. - Tense consistency
Stick to one tense throughout a paragraph unless the context shifts. - Avoid fragments and run-ons
Every sentence must express a complete thought.
Tip: Keep a small list of grammar checks before you submit. It should be part of your academic writing checklist.

2. Use Correct Punctuation Rules in Essays
Punctuation marks are small but powerful. They control the pace, tone, and clarity of your writing. Misusing them can confuse your reader or even change your meaning.
Common Punctuation Rules to Follow:
- Use commas to separate clauses and list items
- Avoid comma splices
Wrong: The theory was flawed, it lacked evidence.
Right: The theory was flawed, and it lacked evidence. - Use colons for explanations and lists
Example: She explored three methods: interviews, surveys, and observations. - Place full stops inside quotation marks
Punctuation is part of your academic writing style guide. When used well, it adds clarity and balance.
3. Follow a Consistent Sentence Structure in Academic Writing
Academic writing is not the place for messy sentences. It should follow a clean and consistent pattern. Stick to subject + verb + object where possible. This helps keep your writing sharp and easy to follow.
Sentence Structure Tips:
- Avoid long sentences with multiple clauses
- Never begin formal academic sentences with “But” or “And”
- Vary your sentence openings, but stay formal
Clear sentence structure supports writing with clarity and coherence. It also reduces your chances of making grammar errors.
If you’re unsure about structure, our editors at Dissertationist can review your draft for structure and flow. You don’t have to struggle alone.
4. Keep Your Academic Tone and Voice Formal
Many students lose marks for being “too casual”. Academic work must sound formal but still be readable. That’s where tone and voice matter.
Rules of Formal English Writing:
- Avoid contractions (write “do not” instead of “don’t”)
- Do not use slang or casual phrases
- Use objective phrases like “The data suggests…” instead of “I think…”
Examples:
Casual: I looked at how teens use social media.
Academic: This study examines social media usage among teenagers.
Tone is not just about how you write—it shows your level of understanding. A clear academic tone builds credibility.
5. Prioritise Writing Clarity and Precision
Clarity means your reader understands your idea in one go. Precision means using the exact words that fit your point. Together, they make your writing strong and professional.
Simple Rules for Writing Clarity and Precision:
- Avoid vague terms like “things”, “stuff”, or “a lot”
- Use specific academic terms where needed
- Make each sentence about one main point
- Cut out extra words that don’t add meaning
Example:
Vague: There are many things that influence climate change.
Clear: Human activities such as deforestation and burning fossil fuels influence climate change.
Always ask: “Can I make this sentence shorter without losing meaning?” That’s the secret to writing clarity and precision.
6. Avoid Common Mistakes in Academic Writing
You may have strong ideas, but simple errors can take away your marks. These are the top mistakes students make—and how to fix them.
Common Mistakes:
- Mixing up “its” and “it’s”
- Using informal language like “kind of” or “a bit”
- Switching tenses halfway through the essay
- Repeating the same point in different words
- Using too many quotes instead of original analysis
Quick Fixes:
- Proofread out loud
- Use an academic checklist before you submit
- Avoid “copy-paste” from online sources
- Stay on one idea per paragraph

7. Maintain Originality and Avoid Plagiarism
Plagiarism is not just copying—it’s using others’ ideas without giving credit. It’s one of the top reasons students fail their essays. To succeed, you must learn how to write in your own words and cite sources properly.
How to Avoid Plagiarism in Academic Writing:
- Use your own analysis
- Paraphrase instead of copying
- Cite all references clearly using the required style (Harvard, APA, MLA, etc.)
- Keep a list of all sources you used
- Run your work through plagiarism checkers
Your university can fail your work if it’s not original. At Dissertationist.co.uk, we guarantee 100% plagiarism-free content. That’s a promise.
