Consistent terminology in a thesis - how to keep the meaning intact

Your methods section says “requests submitted through the online form”. The results say “electronic requests”. Do they mean the same documents?

Your methods section says “requests submitted through the online form”. The results say “electronic requests”. Do they mean the same documents? First check whether the log also includes requests sent by email. If it does, that small change in wording can change what the result means.

Start with one sentence from the results. Underline the name of the group and find the rule you used to select it in the methods section. Note which cases meet that rule. If two terms cover the same cases, settle on one for your own writing. If one term covers more, note where the boundary lies in your working glossary.

Do the two terms refer to the same thing?

Open the two passages side by side. Check what you are describing and what you counted in each. One student can submit two requests, for example. If your methods count requests, changing the wording to “students” in the results would require a separate count of people.

  • Different words for the same requests. If “form submissions” and “form-based requests” refer to exactly the same records, choose the wording that is easier to follow. Here, “requests submitted through the online form” works well.
  • One term covers more cases. If “electronic requests” includes both form and email submissions, use it when referring to both channels together. Name the form explicitly in a paragraph about that channel alone.
  • Authors define a term differently. In your literature review, explain what each author's definition covers. In your methods, state which definition you use in your own study and how you identify the cases it covers.

Maciej Sydor points out that using several synonyms for the same things can make a thesis harder to follow. Tomasz Michta discusses how broader and narrower concepts relate to one another. In our example, that relationship helps explain how two perfectly valid terms can describe groups of different sizes.

The 2025 guidelines from the Faculty of Mechanical Engineering and Aeronautics at Rzeszów University of Technology call for clear writing and vocabulary appropriate to the field. The EASE guidelines for scientific articles in English recommend explaining unusual or ambiguous terms at first use. For a thesis at a university in Poland, check your own faculty's guidance, especially on foreign-language terms and abbreviations.

What belongs in a working glossary?

A sheet of paper or a separate file is enough. Start with terms that appear in both the methods and the results. For each one, note the term you have chosen, the definition, its source and a case that is easy to misclassify. Add any variants and abbreviations you want to search for. The glossary helps you edit. If you are considering a list of terms in the thesis itself, follow your university's guidelines and consider what the reader needs.

An example from a request log

Imagine you are writing a public administration thesis about a student service desk. In the fictional log, the “channel” field shows how each request came in. Two entries in the glossary might look like this.

  • Request submitted through the online form. The channel is marked “form”. If someone emails an attachment with the same fields, the channel is still email.
  • Electronic request. The channel is marked “form” or “email”. Use this as the shared term when you discuss both channels.

Add a rule for when you count a request as closed. In this example, the status must appear in the log by the time observation ends. Each entry represents one request. The same person may submit several.

What does one word change in a result of 62.5%?

The fictional log contains 30 electronic requests. Twenty-four came in through the form and six by email. By the end of the observation period, 15 form submissions had been closed and the other nine were still in progress. The statuses of the six email requests are outside this calculation.

A sentence from the results, before and after editing

Before editing. “62.5% of electronic cases were closed, which means that most students received help.”

After editing. “By the end of the observation period, 15 of the 24 requests submitted through the online form had been closed (62.5%).”

The fraction 15 / 24 applies only to the form. To report the percentage for both channels, you also need the number of closed email requests. The log counts requests, and a closure status only tells you that the entry was closed. To find out how many students received help, you need to check the outcomes and count distinct people.

You could caption the chart “Percentage of online form requests closed”. In the abstract, name the group and give the counts, for example “15 of 24 online form requests were closed”. If the spreadsheet and the draft show different percentages, check which values and filters the calculation uses before you edit the sentence.

Where else should you look for the old term?

  1. Start with your own writing. Search for different forms of the term, including plurals, inflected forms and abbreviations. Use a copy of the file or track changes. Read the sentence and the surrounding paragraph before making each edit.
  2. Keep the wording of your sources. Preserve quotations, source titles and original questionnaire items. If a term from a source needs explaining, add a sentence alongside it. Check the translated abstract too and make sure it refers to the same group.
  3. Move on to the places where you report a result. Compare the research question, methods, subheadings, captions, conclusions and appendix. When a term is unclear, leave a comment with a question you can answer by checking the data, such as “Does this figure include email requests?”.

Read the draft as someone who has never seen the log

Start with a chart caption or a sentence from the conclusion. Can you tell which requests it covers? Go back to the definition and check that it describes the same group. Then read the abstract. If you still need your working glossary to understand the result, clarify the sentence that made you pause.

If the uncertainty comes from a term in a publication, check that your paraphrase preserves the source's meaning. Try the guide to paraphrasing academic sources.

Questions about editing and reviewing a thesis

What is the difference between proofreading and editing?

Proofreading focuses on language accuracy, spelling and punctuation. Editing also addresses sentence structure, style, paragraph organisation, flow and the logic of your argument. I tailor the scope to the condition of your text and the changes it needs.

I offer both proofreading and editing for bachelor's and master's theses, coursework, reports, other academic papers and presentations.

Can an unfinished thesis be checked?

Yes. I can assess existing chapters and their layout, noting which elements cannot yet be checked. A comprehensive assessment of the link between results and conclusions requires providing those parts.

Discuss the terminology in your thesis

Tell us which terms are causing trouble. Include the definition, the passage with the result and any guidelines you have. We can use those to decide whether the wording needs editing or the definition and the way the group was counted need a closer look.

A bachelor’s or master’s thesis abstract should briefly present its aim, approach, main findings and conclusion. Write it from the completed thesis. The English abstract should convey the same content, preserving the correct terminology and study limitations. Your thesis runs to dozens of pages, but the university’s submission system gives you only a small field to describe it. What should you include? Instead of shortening each chapter separately, identify what readers need to know to understand the subject and outcome of the whole thesis. The example below shows how to combine this information without writing a second introduction. The introduction presents the problem and the foundations of the thesis. The conclusion brings together the findings and answers the questions set. The abstract gives a self-contained, condensed account of the whole thesis, including for someone who does not read the other chapters. Do not copy the first paragraph of the introduction if it only explains the importance of the topic. Nor should you transfer the entire conclusion if readers cannot understand the basis for the findings without knowing the method. For comparison, see the guides on writing an introduction and on the thesis conclusion. In her discussion of the summary as a genre, Anna Dunin-Dudkowska (2023) emphasises its dependence on the source text and the selection of essential content. She also describes the importance of an organised account of the problem, method and results in a research abstract. For a thesis, this means the abstract should not add achievements absent from the work itself. Check your faculty’s guidelines and the fields in the thesis submission system. The limit may be stated in words or characters, with or without spaces. Separate language versions and a specified number of keywords may be required. There is no single length that applies to every bachelor’s and master’s thesis. Before shortening...

Bachelor's and master's thesis proofreading vs editing - examples

Proofreading corrects errors in spelling and language, while editing improves how your ideas are presented. A passage may need both. Before sending your thesis for review, explain whether you need language corrections alone or also help with logic, coherence and readability. Thesis proofreading corrects errors in spelling and language, while editing improves how your ideas are presented. The same passage may need both. Before sending your thesis for review, explain whether you need language corrections alone or also help with logic, coherence and readability. Have you finished a chapter but cannot tell what it needs? Start with a few paragraphs. Look separately at language errors, the structure of the argument and whether the content matches your sources. This makes it easier to agree on the scope of support and compare proposals. A request to 'improve a master's thesis' can cover very different tasks. In practice, the boundaries depend on what you agree with the provider. Ask which tasks are included, how changes will be marked and what you will receive. The distinction below helps describe your needs, but the scope for your file still needs to be agreed. Proofreading may cover typos, spelling, punctuation, grammatical forms, syntax and inconsistent abbreviations or terminology. The meaning of each sentence must be preserved. Correcting a comma does not require changing the argument, but it may reveal a sentence so unclear that the author needs to explain the intended meaning. Editing also examines the order of information, connections between sentences, repetition and transitions between paragraphs. An editor may split an overloaded sentence, move an explanation closer to the term it defines or flag a conclusion unsupported by the preceding argument. Changes to the structure of a chapter need a separate agreement. Checking sources, recalculating results, developing missing sections and formatting the document require separate agreement. Someone checking the language should neither supply missing evidence nor guess what actually happened during the study. The examples below are original educational materials and show changes to Polish text. They are not taken from a client’s thesis or a real study.
