Grammar and Clarity in Academic Writing: Common Fixes

Good ideas can be lost in unclear sentences. Markers may not deduct marks for every small slip, but when grammar makes your meaning uncertain, your argument suffers.

This guide focuses on the grammar issues that most often affect international students, and on practical techniques for clearer, more concise writing.

What markers look for

Most marking criteria mention "clarity of expression", "academic style" or "presentation". In practice, markers are asking:

• Can I understand each sentence on the first reading?
• Is the meaning precise, or could it be read in two ways?
• Is the writing concise, or padded with unnecessary words?
• Do errors distract me from the argument?

Notice that the focus is on communication, not perfection. An occasional article error rarely matters; a sentence that cannot be understood does.

Common grammar issues and how to fix them

Articles (a, an, the)

Many languages, including Hindi, Mandarin, Russian and others, use articles differently or not at all, so this is a very common area of difficulty.

• Use a/an for a singular countable noun mentioned for the first time or in general: "a survey".
• Use the when the reader knows which one you mean: "the survey described above".
• Use no article for general plural or uncountable nouns: "Research shows...", "Students often...".

Subject-verb agreement

The verb must agree with the true subject, which is not always the nearest noun.

• Incorrect: "The impact of these policies are unclear."
• Correct: "The impact of these policies is unclear." (the subject is impact)

Watch out for data (treated as plural in some fields, singular in others; follow your discipline), research (uncountable, so "research shows", not "researches show") and each or every (singular).

Tense consistency

Choose tenses for a reason and keep them stable within a section. A common pattern is the present tense for established knowledge and your argument, the past tense for what a specific study or your own method did, and the present perfect for research up to now ("Several studies have examined...").

Sentence fragments

A fragment lacks a main clause. It often begins with because, although or which.

• Fragment: "Although the results were limited."
• Fixed: "Although the results were limited, they suggest a clear trend."

Run-on sentences and comma splices

Two complete sentences joined only by a comma form a comma splice.

• Comma splice: "The sample was small, the findings cannot be generalised."
• Fixed: "The sample was small, so the findings cannot be generalised." Or use a full stop or a semicolon.

Uncountable nouns

Words such as evidence, information, advice, knowledge and equipment are usually uncountable. Write "much evidence" or "several pieces of evidence", not "evidences".

Clarity techniques

Put the subject and verb early

Readers understand sentences faster when they meet the main subject and verb quickly.

• Less clear: "In the context of the increasing complexity of global supply chains and the associated risks for manufacturers, a new approach is proposed by this study."
• Clearer: "This study proposes a new approach to managing risk in increasingly complex global supply chains."

One main idea per sentence

If a sentence runs over three or four lines, check whether it contains two or three ideas. Split it, and link the parts with a clear connector.

Prefer verbs to heavy nouns

Turning verbs into nouns (nominalisation) is part of academic style, but too much makes writing heavy.

• Heavy: "The implementation of the intervention led to an improvement in the reduction of absences."
• Clearer: "The intervention reduced absences."

Cut empty words

Phrases such as "it is important to note that", "in order to", "due to the fact that" and "the reason why is because" can often be shortened or removed.

A step-by-step editing routine for grammar and clarity

1. Leave time between writing and editing, even a few hours, so you read what is actually there.
2. Read aloud. If you run out of breath or stumble, the sentence probably needs restructuring.
3. Check your personal error list. Most writers repeat the same few errors. Keep a list from past feedback and search for those first.
4. Check one issue per pass: articles on one read, agreement on another, long sentences on a third.
5. Use grammar tools carefully. Spelling and grammar checkers catch some errors but also suggest changes that alter meaning. Accept a suggestion only when you understand why it is correct, and check your university's policy on which tools are allowed.
6. Ask whether each sentence says exactly what you mean, not just whether it is grammatical.

Common mistakes when trying to "fix" grammar

• Translating sentence by sentence from your first language, which carries over its word order and article rules.
• Over-correcting by making every sentence long and complex to sound academic.
• Relying on automatic rewriting tools that change your meaning or your voice, and that may not be permitted under your institution's AI-use policy.
• Ignoring feedback patterns. If a marker has commented on articles twice, that is your priority.
• Editing grammar before structure. Polishing sentences in a paragraph you later delete wastes time.

Grammar and clarity checklist

• I have checked articles, especially with countable and uncountable nouns.
• Each verb agrees with its true subject.
• Tense choices are consistent within each section.
• There are no fragments or comma splices.
• Long sentences have been split where they contain several ideas.
• I have removed padding such as "it is important to note that".
• I have checked my personal list of repeated errors.
• I understand every change a grammar tool suggested before accepting it.

Frequently asked questions

Will grammar mistakes lower my mark?

It depends on the marking criteria and how much the errors affect meaning. Many criteria assess clarity and academic style, so frequent errors or unclear sentences can affect that part of the grade. Isolated minor errors are less likely to matter than sentences a marker cannot understand.

Is it acceptable to use a grammar checker?

Many universities allow basic spelling and grammar checkers, but policies on tools that rewrite text, especially generative AI tools, vary widely. Check your institution's academic-integrity and AI-use guidance before using any tool that changes more than individual words.

How can I improve my grammar long term?

Keep a list of the errors that recur in your feedback and focus on those. Reading well-edited articles in your field, noticing how sentences are built, and practising short pieces regularly tend to help more than studying rules in isolation.
