Perhaps the biggest problem non-native academics have when writing in English is sentence structure. When the sentence is not written smoothly, meaning is often lost, and readers become frustrated. It is tempting to translate directly from the native language word for word, but this just does not work in the majority of cases. It must be so frustrating to have the subject knowledge but not be able to express it in a second language.
Here are 10 academic writing rules every researcher should know, with practical examples.
1. Make every sentence serve a purpose
Academic writing should communicate an idea, not simply fill space.
❌ It is important to note that there are many researchers who have conducted studies on this topic.
✅ Many researchers have studied this topic.
Rule: Remove unnecessary introductory phrases and repetition.

2. Make your claims precise
Avoid vague statements such as many, a lot, very, significant, or clearly unless you can substantiate them.
❌ Social media has a very significant impact on students.
✅ A 2025 survey of 1,200 university students found that daily social-media use was associated with lower reported study time.
Rule: Replace vague claims with specific, measurable, evidence-based statements.
________________________________________
3. Support important claims with evidence
A researcher should distinguish between what the evidence shows and what the researcher thinks.
❌ Online learning is clearly better than traditional learning.
✅ Several studies have reported higher learner satisfaction in online courses, although findings vary by course design and student characteristics.
Rule: Cite evidence for claims that are factual, controversial, or derived from previous research.
________________________________________
4. Use cautious academic language
Research rarely proves something absolutely. Use hedging when the evidence warrants it.
Useful expressions include:
• may suggest
• appears to
• is associated with
• is likely to
• could indicate
• the findings suggest
❌ This proves that the intervention works.
✅ These findings suggest that the intervention may improve treatment adherence.
Rule: Match the strength of your language to the strength of your evidence.
________________________________________
5. Prefer active voice when it improves clarity
Passive voice is not always wrong, but using it excessively can make academic writing difficult to read.
❌ The data were collected by the researchers from three universities.
✅ The researchers collected data from three universities.
However, passive voice can be useful when the action is more important than the actor:
✅ The samples were stored at −20°C.
Rule: Choose the voice that makes the sentence clearest, rather than following a blanket “always use active voice” rule.
________________________________________
6. Give each paragraph one central idea
A strong paragraph usually has a clear progression:
Topic sentence → evidence → explanation → connection
❌ A paragraph jumps between methodology, results, theory, and unrelated literature.
✅ The paragraph begins with the relationship between variables, presents relevant evidence, explains its significance, and connects it to the research question.
Rule: If you cannot summarize a paragraph’s main point in one sentence, it may need restructuring.
________________________________________
7. Build logical connections between ideas
Don’t make the reader infer how one sentence relates to the next.
Useful transitions include:
Adding: Furthermore, similarly, in addition
Contrasting: However, nevertheless, in contrast
Cause/effect: Therefore, consequently, as a result
Qualification: Although, despite this, nevertheless
Example:
❌ The intervention increased participation. Previous studies reported similar findings. The sample was relatively small.
✅ The intervention increased participation, consistent with findings from previous studies. However, the relatively small sample limits the generalizability of these results.
Rule: Make the logic between ideas explicit.
________________________________________
8. Define important terms consistently
Do not use technical terms as though their meaning is automatically obvious.
❌ The study examines student engagement.
What counts as engagement—attendance, participation, time-on-task, or something else?
✅ In this study, student engagement refers to students’ participation in course activities, measured through attendance and assignment completion.
Rule: Define key concepts, particularly when they can have multiple meanings.
________________________________________
9. Separate results from interpretation
One of the most important rules in research writing is distinguishing what you found from what you think the finding means.
Results:
Participants who received the intervention reported a 15% increase in weekly exercise.
Discussion/interpretation:
This increase may indicate that the intervention improved participants’ motivation to exercise.
The first statement reports an observation. The second interprets it.
Rule: Don’t present an interpretation as though it were a directly observed fact.
________________________________________
10. Revise for clarity, not just grammar
A grammatically correct paper can still be difficult to read.
Instead of only asking:
“Is this sentence grammatically correct?”
also ask:
• Is the meaning immediately clear?
• Is the sentence unnecessarily long?
• Is the subject obvious?
• Can I remove unnecessary words?
• Does this paragraph have a logical progression?
• Does the evidence actually support the claim?
• Would another researcher interpret this sentence the way I intend?
❌ Due to the fact that the participants who were involved in the study were predominantly individuals who had previously experienced difficulties in relation to academic achievement, it could perhaps potentially be suggested that…
✅ Because most participants had previously experienced academic difficulties, the findings may suggest that…
Rule: Clarity is more important than sounding complicated.
The 10 rules in one checklist
# Rule Ask yourself
1 Be purposeful. Does every sentence contribute something?
2 Be precise. Can I replace vague language with specifics?
3 Use evidence. What supports this claim?
4 Hedge appropriately. Am I claiming more than the evidence allows?
5 Use voice strategically. Is the sentence as clear as possible?
6 Focus paragraphs. What is this paragraph’s central idea?
7 Show logical connections. Can the reader see how the ideas connect?
8 Define key terms. Have I made important concepts unambiguous?
9 Separate finding from interpretation. What did I observe vs. what do I infer?
10 Revise for clarity. Can this be understood more quickly and accurately?
Good academic writing is not about using the most complicated vocabulary. It is about making precise claims, supported by evidence, expressed with appropriate caution, and organized so the reader can follow the argument.
