Clarifying Wording Without Changing Meaning

By Dr. Zubair Khalid, DVM, MS, PhD · 2026-08-28

Quick Answer

• Clarify ambiguous wording in manuscript revisions by first identifying the exact phrase under question, then testing each rewrite for semantic equivalence against the original meaning.
• Use parallel structures and consistent terminology to maintain clarity while addressing reviewer concerns about precision or readability.
• The main limitation is that semantic equivalence testing requires careful judgment, and no rewrite can guarantee the author's intended meaning is preserved without author verification.

Understanding the Reviewer's Concern About Wording

Peer reviewers often flag ambiguous phrasing because unclear language can obscure the scientific contribution of a manuscript. When a reviewer asks for clarification, they are typically signaling that a sentence, term, or passage could be interpreted in more than one way. This ambiguity can affect how readers understand your methods, results, or conclusions.

The Committee on Publication Ethics Core Practices emphasize that peer review should help authors improve their work through constructive feedback. Reviewers who request wording changes are not necessarily questioning the validity of your research. They are asking for precision so that the record of your work is accurate and reproducible.

Ambiguity in scientific writing usually falls into several categories. Pronoun references that could point to multiple antecedents create confusion. Vague quantifiers such as "several" or "many" without context leave the reader guessing. Technical terms used inconsistently across sections can mislead. Passive constructions sometimes hide who performed an action or what was measured. Each of these issues requires a different clarification strategy.

The Core Principle of Semantic Equivalence

The central challenge in clarifying wording is preserving the original meaning while improving clarity. Semantic equivalence means that the rewritten sentence conveys exactly the same factual content as the original, with the same scope, conditions, and limitations. A rewrite that changes the meaning is not a clarification. It is an error that can affect the integrity of your reported work.

To test for semantic equivalence, you need to compare the original and revised versions against a set of criteria. The subject of the sentence must remain the same. The action or relationship described must not change. Any conditions, exceptions, or qualifiers must be preserved. And the level of specificity must stay consistent. If the original says "some samples," the revision cannot say "all samples" or "most samples."

The National Library of Medicine Research Methods Resources provide guidance on how precise language supports sound research methodology. Clear descriptions of methods and results allow other researchers to understand what was done and to evaluate whether the conclusions are supported by the evidence.

Identifying Ambiguous Phrases

Before you can clarify a sentence, you must identify which phrase is causing the problem. Start by reading the reviewer comment carefully. The reviewer may quote the specific sentence or phrase that concerns them. If they do not, look for the sentence that corresponds to their broader comment about clarity.

Common sources of ambiguity include pronouns with unclear antecedents. For example, "The treatment was applied to the cells and then they were incubated" leaves the reader wondering whether "they" refers to the cells or the treatment. Similarly, "The results were compared with the control group and the data was analyzed" does not make clear whether the data came from the treatment group, the control group, or both.

Another common issue is the use of terms that have multiple meanings in your field. A word like "significant" can mean statistically significant or practically important. "Normal" can mean standard, typical, or within a reference range. When a reviewer flags such a term, you need to specify which meaning you intend.

A Framework for Rewriting Ambiguous Sentences

Once you have identified the ambiguous phrase, you can apply a structured approach to rewriting it. This framework helps you move from a vague sentence to a precise one without losing the original content.

Step 1: State the Intended Meaning

Write down what you actually mean in plain language. Do not worry about style or elegance at this stage. Focus on the factual content. If you cannot state the intended meaning clearly, you may not fully understand what you were trying to say in the original sentence.

Step 2: Identify the Ambiguous Element

Determine which part of the sentence creates the ambiguity. Is it a pronoun, a modifier, a verb, or a clause? Is the ambiguity about what was done, when it was done, or to what it was done? This identification tells you what kind of revision is needed.

Step 3: Choose a Clarification Strategy

Different types of ambiguity require different strategies. For a pronoun with an unclear antecedent, replace the pronoun with the noun it refers to. For a vague quantifier, provide the actual number or range. For a technical term with multiple meanings, add a definition or use a more specific term. For a sentence that combines multiple ideas, split it into separate sentences.

Step 4: Test for Semantic Equivalence

Compare the revised sentence with your statement of intended meaning. Does the revision say exactly what you meant? Does it include any additional information that was not in the original? Does it omit any information that was in the original? If the answer to any of these questions is yes, the revision is not semantically equivalent.

Step 5: Check the Context

Read the revised sentence in the context of the surrounding paragraph. Does it still fit with the sentences before and after it? Does it create any new ambiguity by changing the flow of the text? Sometimes a sentence that is clear in isolation becomes confusing when placed in a paragraph.

Using Parallel Structures to Maintain Clarity

Parallel structure is a powerful tool for clarifying scientific writing. When you present two or more items in a sentence, they should follow the same grammatical form. This consistency helps the reader understand that the items are being compared or contrasted.

For example, consider the sentence "The study measured the effect of temperature on growth and how the pH affected the results." This sentence is awkward because the two clauses have different structures. A parallel revision would be "The study measured the effect of temperature on growth and the effect of pH on the results."

Parallel structures also help when you are listing conditions, methods, or outcomes. If you write "The samples were collected, then we analyzed them, and the results were recorded," the sentence mixes active and passive voice. A parallel version would be "The samples were collected, analyzed, and recorded."

The EQUATOR Network provides reporting guidelines that emphasize clear and complete descriptions of research methods. These guidelines often require that methods be described in a consistent and structured way, which parallels the use of parallel structures in individual sentences.

At a Glance

Testing Semantic Equivalence

Once you have drafted a revision, you need to test it for semantic equivalence. This testing is not a formal statistical procedure. It is a careful reading and comparison of the original and revised sentences.

The Substitution Test

Read the original sentence and the revised sentence side by side. Ask whether the revised sentence could be substituted for the original in the manuscript without changing the meaning of the surrounding text. If a reader who saw only the revised version would understand the same thing as a reader who saw only the original, the revision is semantically equivalent.

The Question Test

Ask questions about the original sentence and see whether the revised sentence answers them in the same way. For example, if the original says "The treatment was applied," ask "What was applied?" and "To what was it applied?" The revised sentence should answer these questions identically.

The Scope Test

Check whether the revised sentence has the same scope as the original. If the original says "The method was used in all experiments," the revised sentence cannot say "The method was used in most experiments." If the original says "The results suggest," the revised sentence cannot say "The results prove."

The Omission Test

Read the revised sentence and ask whether it omits any information that was in the original. This test is especially important when you are trying to shorten a sentence for clarity. A shorter sentence is not necessarily a clearer sentence if it loses important details.

Common Failure Patterns in Rewriting

Several common mistakes occur when researchers attempt to clarify their wording. Recognizing these patterns can help you avoid them.

Changing the Scope

The most serious error is changing the scope of a claim. If the original says "The treatment reduced the risk of infection," a revision that says "The treatment eliminated the risk of infection" changes the meaning. Similarly, changing "some" to "all" or "often" to "always" alters the factual content.

Adding Information

A revision that adds new information is not a clarification. If you find yourself adding details that were not in the original, you are changing the content of the manuscript. This may be appropriate if the reviewer asked for more information, but it is not a pure wording clarification.

Removing Information

The opposite error is removing information to make a sentence shorter. If the original includes a condition or limitation, the revision must retain it. For example, "The method was effective under controlled conditions" cannot be shortened to "The method was effective" without changing the meaning.

Introducing New Ambiguity

Sometimes a revision that fixes one ambiguity creates a new one. For example, replacing a pronoun with a noun may make the sentence longer and more complex, introducing a new unclear reference. Always read the revised sentence in context to check for new problems.

Inconsistent Terminology

If you change a term in one sentence, you must check whether the same term appears elsewhere in the manuscript. Using two different terms for the same concept can confuse readers. The National Institutes of Health Grants and Funding resources emphasize the importance of clear and consistent language in research proposals and reports.

Practical Workflow for Responding to Reviewer Comments

When you receive reviewer comments that ask for clarification, follow a structured workflow to ensure that your revisions are accurate and complete.

Step 1: Read All Comments First

Before making any changes, read all of the reviewer comments. This gives you an overview of the concerns and helps you identify any comments that are related. A single ambiguous sentence may be flagged by more than one reviewer.

Step 2: Categorize the Comments

Separate the comments into categories. Some comments may ask for clarification of wording. Others may ask for additional analysis or new experiments. The clarification comments are the focus of this article, but you need to understand the full scope of the revision.

Step 3: Draft Revisions for Each Comment

For each clarification comment, identify the specific sentence or phrase that needs revision. Draft a revised version using the framework described above. Do not try to revise all sentences at once. Work on one sentence at a time.

Step 4: Test Each Revision

Apply the semantic equivalence tests to each revision. Check for consistency with the rest of the manuscript. Make sure that the revision does not change the meaning of any other sentence.

Step 5: Write the Response Letter

In your response letter, explain what you changed and why. For each clarification, state the original sentence, the revised sentence, and a brief explanation of how the revision addresses the reviewer's concern. The Committee on Publication Ethics Core Practices emphasize that authors should respond to reviewer comments in a professional and transparent manner.

Step 6: Check for Consistency Across the Manuscript

After you have made all of the revisions, read the entire manuscript to check for consistency. Make sure that the revised sentences fit with the surrounding text and that no new inconsistencies have been introduced.

Records and Measurements

Keeping records of your revisions is important for several reasons. First, you need to be able to explain your changes in the response letter. Second, you need to be able to verify that you have addressed all of the reviewer comments. Third, you may need to refer to the original version of the manuscript if questions arise later.

Revision Log

Create a revision log that lists each reviewer comment, the sentence that was revised, the original wording, the revised wording, and the reason for the change. This log can be a simple table or a spreadsheet. It serves as a record of your work and helps you ensure that no comment is overlooked.

Version Control

Keep separate versions of your manuscript. The original version, the version with revisions, and the final version should be clearly labeled. This practice is especially important if you are working with co-authors who need to review the changes.

The Response Letter

The response letter is a formal record of your revisions. It should be organized by reviewer and by comment number. For each comment, you should state the original sentence, the revised sentence, and an explanation of the change. The National Institutes of Health Grants and Funding resources emphasize the importance of clear and complete documentation in research.

Common Failure Patterns in Responding to Reviewers

Researchers often make mistakes in how they respond to reviewer comments about wording. These mistakes can delay publication or lead to additional rounds of review.

Ignoring the Comment

Some researchers choose to ignore a comment about wording if they believe the original sentence is clear. This approach is risky. The reviewer has identified a problem, and ignoring it may lead to a rejection or a request for further revision.

Arguing with the Reviewer

A response that argues with the reviewer about whether the sentence is ambiguous is usually not productive. Even if you believe the original sentence is clear, the reviewer has indicated that they found it unclear. A better approach is to revise the sentence to be clearer and explain in the response letter that you have revised the wording to address the concern.

Making Unrelated Changes

Some researchers use the revision process to make changes that are not related to the reviewer comments. This practice can introduce new errors and make it harder for the reviewer to evaluate the revision. If you need to make additional changes, you should note them separately in your response letter.

Failing to Check the Context

A revision that is clear in isolation may be confusing in the context of the paragraph. Always read the revised sentence in the full paragraph to check that it flows well and does not create new problems.

The Role of Reporting Guidelines

Reporting guidelines are checklists that help authors ensure that their manuscripts include all the necessary information. The EQUATOR Network provides a comprehensive collection of reporting guidelines for different study types. These guidelines can help you identify sections of your manuscript that may be unclear or incomplete.

When a reviewer asks for clarification of wording, the issue may be related to a reporting guideline. For example, a reviewer might ask you to clarify how you measured a particular outcome. The relevant reporting guideline may specify that the measurement method should be described in detail. Using the guideline can help you understand what the reviewer is looking for.

The Connection to Data Management

Clear wording is also important in the context of data management. The NIH Data Management and Sharing Policy requires that research data be described in a way that is clear and understandable. If your manuscript describes data that you will share, the wording must be precise enough for other researchers to understand what the data are and how they were collected.

Professional Escalation Criteria

There are situations where you should seek additional help with a revision. If you are unsure whether a revision is semantically equivalent, you should ask a co-author or a colleague to review the change. A second reader can often identify problems that you have missed.

If the reviewer's comment is unclear, you may need to contact the journal editor for clarification. The editor can help you understand what the reviewer is asking for. This step is appropriate when the reviewer's comment is vague or when you are unsure how to address it.

If you believe that the reviewer's comment is based on a misunderstanding of your work, you should explain this in your response letter. You should not simply ignore the comment. Instead, you should provide a clear explanation of why the original wording is correct and why you have not changed it.

The Importance of Author Verification

The final responsibility for the accuracy of the manuscript rests with the authors. No reviewer, editor, or colleague can verify that a revision preserves the intended meaning. Only the authors know what they meant to say in the original sentence.

This is why the semantic equivalence test is so important. Before you submit your revised manuscript, you should read each revised sentence and ask whether it says what you meant. If you are not sure, you should revise it again.

The ORCID for Researchers page emphasizes the importance of maintaining an accurate record of your research contributions. This principle extends to the accuracy of the manuscripts you publish. A manuscript with clear and accurate wording is part of your research record.

Practical Steps for the Revision Process

The following steps provide a practical approach to revising your manuscript in response to reviewer comments about wording.

Step 1: Create a Comment Table

Create a table with columns for the reviewer number, the comment number, the original sentence, the revised sentence, and the status of the revision. This table helps you track your progress and ensures that you address every comment.

Step 2: Revise One Sentence at a Time

Work through the table one sentence at a time. For each sentence, apply the framework described above. Do not move to the next sentence until you have tested the revision for semantic equivalence.

Step 3: Read the Revised Manuscript

After you have revised all of the sentences, read the entire manuscript. This reading helps you check for consistency and flow. You may find that a revision that was clear in isolation is confusing in context.

Step 4: Ask a Colleague to Review

Ask a colleague to read the revised manuscript and compare it with the original. Ask them to identify any sentences where the meaning may have changed. This independent check can catch errors that you have missed.

Step 5: Write the Response Letter

Write the response letter that explains each revision. The letter should be clear and professional. It should not argue with the reviewer but should explain what you have changed and why.

The Role of the Journal Editor

The journal editor is responsible for managing the peer review process. If you have questions about a reviewer comment, the editor can help. The editor can also help you if you believe that a reviewer comment is unreasonable or based on a misunderstanding.

The Committee on Ethics Core Practices describe the responsibilities of editors in the peer review process. Editors are expected to handle manuscripts fairly and to ensure that the review process is conducted properly. If you have a concern about the review process, you should contact the editor.

Limitations of the Clarification Process

The process of clarifying wording has limitations. First, it is not always possible to make a sentence completely unambiguous. Some scientific concepts are complex and require careful reading. The goal is to reduce ambiguity, not to eliminate it entirely.

Second, the semantic equivalence test is subjective. Different readers may have different opinions about whether a revision preserves the original meaning. This is why it is helpful to have a colleague review your changes.

Third, the clarification process can be time-consuming. It requires careful reading and rewriting. However, the time spent on clarification is worthwhile because it improves the quality of the manuscript.

The Relationship Between Clarity and Reproducibility

Clear wording is essential for reproducibility. If a reader cannot understand what you did, they cannot replicate your work. The NIH Data Management and Sharing Policy emphasizes the importance of describing research methods clearly so that others can understand and reproduce the work.

When you clarify a sentence, you are beyond improving the style of the manuscript. You are improving the reproducibility of your research. A reader who understands your methods is better able to replicate your work and to evaluate your conclusions.

The Role of the Research Methods Resources

The National Library of Medicine Research Methods Resources provide a gateway to authoritative biomedical books and research-method references. These resources can help you understand the methods that you are describing in your manuscript. If you are unsure about the correct terminology for a method, these resources can help you find the right terms.

The Importance of Clear Terminology

Clear terminology is a key part of scientific writing. When you use a term that has multiple meanings, you need to define it or use a more specific term. For example, if you use the term "significant" to mean "statistically significant," you should say "statistically significant" or define the term in the context of your manuscript.

The EQUATOR Network provides reporting guidelines that often specify the terminology that should be used in a particular type of study. Using the correct terminology helps ensure that your manuscript is clear and that it meets the expectations of the journal.

The Role of the Response Letter

The response letter is an important part of the revision process. It is your opportunity to explain your changes to the reviewer and to the editor. A clear response letter can help the reviewer understand your revisions and can speed up the review process.

The response letter should be organized by reviewer and by comment. For each comment, you should state the reviewer's comment, your response, and the change that you made. You should also explain why you made the change and how it addresses the reviewer's concern.

The Importance of Professionalism

The revision process should be conducted professionally. You should respond to the reviewer's comments in a respectful manner, even if you disagree with them. The Committee on Ethics Core Practices emphasize the importance of professional conduct in the peer review process.

The Role of the Editor

The editor is responsible for making the final decision about the manuscript. The editor will consider the reviewer's comments and your response. If you have addressed the reviewer's comments clearly, the editor is more likely to accept the manuscript.

The Final Check

Before you submit the revised manuscript, you should do a final check. Read the entire manuscript and check for any remaining ambiguity. Check that the revised sentences are consistent with the rest of the manuscript. Check that the response letter is complete and clear.

Frequently Asked Questions

How do I know if a reviewer is asking for clarification or for a change in content?

A reviewer who asks for clarification is asking you to make the wording clearer. A reviewer who asks for a change in content is asking you to change the substance of the manuscript. The distinction is not always clear. If you are unsure, you can contact the editor for clarification.

What should I do if I cannot clarify a sentence without changing its meaning?

If you cannot clarify a sentence without changing its meaning, you should consider whether the original sentence is accurate. If the original sentence is accurate but ambiguous, you may need to add more information to make it clear. If the original sentence is not accurate, you need to correct it.

How long should my response letter be?

The response letter should be as long as it needs to be to address all of the reviewer's comments. It should be clear and organized. It should not be unnecessarily long, but it should not omit important information.

Should I change the wording if I believe the original is clear?

If you believe the original wording is clear, you can explain this in your response letter. However, you should consider the reviewer's perspective. If the reviewer found the wording unclear, it may be unclear to other readers as well. It is often better to revise the wording to be clearer.

How do I check for semantic equivalence?

You can check for semantic equivalence by comparing the original and revised sentences. Ask whether the revised sentence says the same thing as the original. Check that the scope, conditions, and limitations are the same. Ask a colleague to review the changes.

What should I do if the reviewer asks for a change that I believe is incorrect?

If you believe that the reviewer's requested change is incorrect, you should explain your reasoning in your response letter. You should provide evidence to support your position. You should not simply ignore the reviewer's comment.

How do I handle comments from multiple reviewers?

When you receive comments from multiple reviewers, you should address each comment separately. You should organize your response letter by reviewer and by comment. You should ensure that you have addressed all of the comments from all of the reviewers.

What is the role of the editor in the revision process?

The editor is responsible for managing the peer review process. The editor can help you understand the reviewer's comments and can clarify any questions you have. The editor makes the final decision about the manuscript.
