Before and After Editing: Proofreading and Copyediting Applied to the Same Paragraph
Proofreading and copyediting are distinct services that produce different results. Following the same paragraph through each service illustrates the difference more clearly than a comparison of definitions.
This worked example presents a single original paragraph and shows the changes made by proofreading and by copyediting, so that the difference between the two services is evident in the edits themselves rather than only in their definitions.
Learning objectives
- The changes made by proofreading and the elements it leaves unchanged.
- The additional changes made by copyediting beyond the scope of proofreading.
- How a sample of an author’s own draft indicates which service is required.
Common misconceptions
- “Proofreading and copyediting are essentially the same service offered at different prices.” Proofreading corrects surface errors (spelling, punctuation, grammar and consistency) without altering sentence structure or word choice, whereas copyediting additionally improves clarity, flow and word choice at the sentence level. The two services address different problems; they are not the same service applied with different degrees of attention.
The original paragraph
Illustrative original draft: "The results of our study shows that the intervention group had a significant decrease in symptoms compared to control group, which is consistent with previous studys that has investigated this kind of interventions in similar patient populations and settings."
The paragraph after proofreading
"The results of our study show that the intervention group had a significant decrease in symptoms compared to the control group, which is consistent with previous studies that have investigated this kind of intervention in similar patient populations and settings." Note: subject-verb agreement, article usage, plural forms, and spelling are corrected; the sentence structure, length, and word choice are otherwise left exactly as written by the author.
The paragraph after copyediting
"The intervention group showed a significant decrease in symptoms relative to the control group — consistent with prior studies of similar interventions in comparable populations and settings." Note: this corrects the same surface errors, but also restructures the sentence for directness (active rather than passive framing), tightens the wording ("relative to" replacing the wordier "compared to"), and removes redundancy ("similar... and settings" tightened) — changes a proofread alone would not make.
Determining the appropriate service
If a draft is already well structured and clearly worded and requires only a final error check before submission, proofreading is the appropriate (and typically faster, less expensive) service. If the sentences of a draft are grammatically correct but remain unclear, wordy, or awkward, copyediting addresses that level of the writing, which proofreading by design does not.
Key points
Key points
Proofreading corrects surface errors without altering sentence structure or word choice, whereas copyediting corrects surface errors and also improves structure, clarity and wording. Comparing the same paragraph after each service demonstrates the practical difference more clearly than definitions alone.
Practical application
Practical application
- Authors should assess a sample paragraph of their draft against both standards. A draft that is grammatically correct but remains unclear or verbose requires copyediting rather than proofreading alone.
- A clean draft should not be assumed to require copyediting by default. A well-structured, clearly worded draft may require only the lighter and faster proofreading pass.
- The service requested should be specified, because the two produce substantively different results. Editing should not be assumed to be a single, undifferentiated service.
Frequently asked questions
No; copyediting improves clarity and flow without changing the substantive meaning or claims. A change that alters meaning would constitute a substantive edit, which is a different and more involved service.
Proofreading does not replace the structural and clarity improvements of copyediting; where both are needed, copyediting is typically performed first (since it may introduce new text that itself requires proofreading), followed by a final proofreading pass.
If entire sections require reorganising or arguments require restructuring beyond the sentence level, substantive or developmental editing, rather than copyediting, is indicated.

Self-check: which service is required?
This test should be applied to a paragraph from the author’s own draft.
Is the paragraph grammatically correct, with no spelling or punctuation errors? ___ Is the sentence structure clear, direct, and free of redundancy? ___ Both yes → likely just needs a final proofread First yes, second no → likely needs copyediting

How Pubrica can help
Pubrica offers proofreading and copyediting as distinct services and assists authors in identifying which one a draft requires before work begins.
