What is "in-depth" proofreading?

"In-depth" proofreading and editing simply means a substantive scrutiny of your dissertation or thesis, one that goes far beyond the correction of superficial English language errors.

In this PhD & Master's thesis proofreading service, our experienced academic editors dig deep into your academic paper not only to correct spelling, grammar and punctuation mistakes, but also fix other more problematic and serious writing issues such as repetitive text, inconsistency, incoherence, wordiness, lack of clarity and flow, or gaps in academic writing.

It might be the case that you have conducted the most extensive research for your PhD or MA degree and put every effort into it. However, failing to present all that great research work and your findings in a well-written and concise dissertation paper will undo every academic effort you have made to be awarded your degree.

In short, this comprehensive thesis proofreading service is designed to ensure your thesis or dissertation is written and presented in exceptionally high standard academic language in order to help you attain the highest grade possible.

How do we proofread your thesis in depth?

We will scrutinise your manuscript, word by word and line by line, to identify and correct:

  • Grammatical errors;
  • Lexical errors;
  • Syntactic errors;
  • Semantic errors;
  • Typographical errors (extra letters, incorrect spacing between words, additional full stops).
  • Consistency: the use of fonts, line spacing, italics, bold type, and headings/sub-headings (such as numbering, underlining).
  • Coherence, intelligibility and readability

a) Grammar, punctuation, and spelling


a) Subject-verb agreement (SVA) 

Although it is one of the most fundamental and basic rules in the English language, a large number of corrections our proofreaders make in dissertations and theses are related to subject-verb agreement errors. This is often the result of academic students using excessively long or badly structured sentences when drafting their manuscript. It can also happen when relying on automatic grammar correction tools. In this case, the doer of the verb becomes obscured.

Let's look at this example:

Original: The three main pillars of social science theory, which is employed by the researcher, serves the purpose of the study perfectly.

Edited: The three main pillars of social science theory, which is employed by the researcher, serve the purpose of the study perfectly.

Here is another example:

Original: Figure 3, which highlights the three shapes, mainly focus on the processes and duration of each activity.

Edited: Figure 3, which highlights the three shapes, mainly focuses on the processes and duration of each activity.  

b) Use of conjunctions/connectors 

In good academic writing, using connectors or conjunctions is impertative in order to piece your ideas and arguement together and transit smoothly from a theme or sub-theme to another. Conjunctions also help the flow of language as you move from paragraph to another. Very often, MA and PhD students either omit to use connectors altogether, or ignore them completely. When drafting your dissertation or thesis, you have to strike the right balance when using conjunctions. After all, they have to serve a purpose and be employed in a meaningful way. Punctuating them correctly is a separate and important matter.

Let's look at an example:

Original: The generalisability of the conclusions is affected by the sample size, however, the conclusions can still enrich knowledge and serve future research.

Edited (1): The generalisability of the conclusions is affected by the sample size; however, the conclusions can still enrich knowledge and serve future research.

Edited (2): The generalisability of the conclusions is affected by the sample size. However, the conclusions can still enrich knowledge and serve future research.

The connector "however" in the first sentence is mispunctuated as it is preceded by a comma and followed by a comma. This is a very common error we correct in thesis and dissertation papers.

c) The use of tenses 

Using tenses correctly in an academic manuscript such as a dissertation is extremely important. This is because MA and PhD students are expected to use different tenses (future, present and past) throughout the thesis paper, depending on each section. The tense used in the literature review part, for instance, may not be the right tense to use in the abstract, findings or conclusion. Failure to use tenses correctly in your thesis or dissertation will at least leave your text unreadable and confusing – and above all can cause you to lose important marks.

Original: In this academic study, I aim to investigate the phenomenon which I presented in detail in the following section.

Edited: In this academic study, I aimed to investigate the phenomenon which I will present in detail in the following section. (Note: you already aimed and conducted the research on the phenomenon, so the past tense, rather than present, had to be used in this instance).

Original: I have reviewed the literature for my thesis two weeks ago.

Edited: I reviewed the literature for my thesis two weeks ago.

Original: I will collect my data through semi-structured interviews. Three interviews were conducted with senior managers of the companies included in the study.

Edited: I collected my data through semi-structured interviews. Three interviews were conducted with senior managers of the companies included in the study. 

d) The use of modifiers 

It's and its are very often confused. Its is a possessive pronoun and it simply means "belonging to", but it's is an abbreviated or contracted form of either it is or it has.

Original: The proofreader said the chapter was well written, but it's content needed further detail.

Edited: The proofreader said the chapter was well written, but its content needed further detail.

e) The use of apostrophe, lower and upper case.

Although it sounds simple, misplacing an apostrophe can change the entire meaning of the sentence. So getting your apostrophe right in your thesis or dissertation is essential.

Look at this example:

Original: The tutors' complaint was that the student was not following a qualitative research method.

Edited: The tutor's complaint was that the student was not following a qualitative research method.

There are a myrid of words that are either capitalised and should be used in lower case or the other way round. One example follows:

Original: The phenomenon was discussed at the level of the Whole World.

Edited: The phenomenon was discussed at the level of the whole world. 

2. Spelling 

In English, there are many tricky, confusing and commonly misspelt words, including adjectives, verbs and names. We pick them up and correct them if they occur in your dissertation/thesis. 

a) Words 

Stationery (stationary), grammer (grammar), loose (lose - as a verb), believes (beliefs - as a noun), proof read (proofread), weak (week), affect (effect) etc.

Hum (Hume), Aristole (Aristotle), Daved (David) etc 

b) Typographical errors

  • They wanted too (to) discuss this in their academic paper.
  •  In the peeface (preface), they explained what they will discuss in their thesis.
  • Proofreading services are impotent (important).

c) American/British English 

If you are studying at a UK university, you will be expected to use British English in your dissertation paper. Similarly, if you are studying at a US university, you will be expected to write your academic manuscript in American English. Not many proofreaders are aware of the differences between American English and British English. But our editors and proofreaders will replace any American words or expressions with British equivalents or vice versa, depending on your required British variant, as exemplified below:

  •  Learned (American) Learnt (British)
  • Focussed (American) Focused (British)
  •  Center (American) Centre (British)
  •  Elective (North American) Optional course of study (British)
  • Characterize (American) Characterise (British)

3. Punctuation 

Punctuation is one of the most divisive elements of language and is one of the trickiest to get right in your dissertation/thesis. Some punctuation-related errors are too simple and result from oversight, but others simply result from the writer's inability to punctuate correctly.
Note: Failure to punctuate your sentences correct while drafting your dissertation can alter the meaning and eventually undermine the accuracy of your writing. The good news is:  our expert native English speaker editors will ensure correct punctuation throughout your paper.

a) The full stop 

Original: Jones and Smith (1994) argue that a model of risks and hazards could potentially have an impact on human safety, this is because harm is the result of human error, in their view.

Edited: Jones and Smith (1994) argue that a model of risks and hazards could potentially have an impact on human safety. This is because harm is the result of human error, in their view. 

b) The colon (common error) 

Original: Numerous researchers argue that cognitive biases emerge at three levels, social, economic, and cultural.

Edited: Numerous researchers argue that cognitive biases emerge at three levels: social, economic, and cultural. 

c) The semicolon 

Original: Several of the participants reported feeling anxious during the experiment, however, they were reassured during the post-experiment briefing that this was a perfectly normal reaction.

Edited: Several of the participants reported feeling anxious during the experiment; however, they were reassured during the post-experiment briefing that this was a perfectly normal reaction. 

d) Quotation marks 

Original: However, although this might seem obvious, Xavier (2016, p.2) states that there exists a lack of effective curricula and learning/teaching materials on comprehensive sex education and adolescents get most of the information from their peers. Most of the time it will be vague and unclear information.

Edited: However, although this might seem obvious, Xavier (2016, p.2) states that, “there exists a lack of effective curricula and learning/teaching materials on comprehensive sex education and adolescents get most of the information from their peers. Most of the time it will be vague and unclear information.” 

b) Language clarity and flow 

As part of the profound dissertation proofreading services, our specialist academic copy-editors – who have a great eye for detail – look carefully at clarity, intelligibility and flow in your entire academic manuscript.

This includes:
1) Refining the use of language so that it is appropriate to your academic discipline and is free of slang/colloquial expressions/informal language.
2) Removing any superfluous, redundant, or unnecessary words or phrases.
3) Identifying and fixing any phrases or sentences that are unnecessarily repeated.
4) Ensuring the referencing style has been applied correctly and consistently throughout. 

c) Writing style & word choice 

Our specialist academic editors and proofreaders will also enhance the style of your dissertation, without changing it.

Some dissertations are written in the form of a personal account and others are drafted in a neutral, formal academic voice.

Our editors & proofreaders will improve on the style you use in your paper. For instance, if the writing style is formal and academic, they will ensure any colloquial words and expressions are taken out and replaced with appropriate alternatives.

They will also introduce more dynamic words in place of bland, commonplace, or overused words (e.g., “exhibits”, “illustrates”, “demonstrates”, rather than “shows”).

If the writing style is more personal, our proofreaders & editors will improve the manuscript by introducing richer and more expressive vocabularly, removing any unnecessary repetition and ensuring the tone is personal, rather than formal neutral. 

d) Sentence structure, referencing 

In this in-depth proofreading and editing service, we will focus closely on improving the structure of your sentences in the following ways:

1) Reordering some sentences as/when necessary.
2) Adding sentences/phrases that link sections or paragraphs together. This further enhances the logical flow of your essay.
3) The addition of well-chosen connecting words that can help link one sentence to the next, such as “however”, “nevertheless, “moreover”, and “furthermore”.
4) Identifying and highlighting any sections of the work whose meaning is unclear.

References/Bibliography: We will also check that all in-text citations are correctly formatted and cited throughout the paper, based on your preferred referencing style, whether APA, Harvard, MLA or others. We will also check and correct your bibliography in line with your referencing style. 

e) Length/Reduction 

A dissertation or thesis must be of a certain length, which usually means adhering to a specified maximum word count.

This can sometimes be very challenging to meet, as many students/academics exceed the required length. Our team of specialist editors will therefore help reduce your academic paper so that it falls within the required limits. Often this is achieved by removing redundant or repeated information/words and tightening the use of grammar.

Sometimes, however, it will also involve combining and condensing key ideas and information, and replacing lengthy phrases with just one or two key words that convey the same meaning. Students often feel this is one of the most valuable services offered by our specialist editors and proofreaders.

Mechanical and formatting errors in your thesis/dissertation?

  • Double spaces between characters, especially after a full stop wrong or missing headings or titles in a table, or captions misaligned columns or rows in a table
  • Misaligned margins
  • Misaligned headings
  • Incorrect text references
  • Inconsistent bullet formatting
  • Incorrect fonts/font sizes
  • Incorrect capitalisation
  • Footnotes or endnotes 
  • Interchanging small words such as: of/off/on, and/an/as, or it/is/if incorrect use of trademarks
  • Missing numbers in a numbered sequence/list incorrect dates
  • Inconsistent use of abbreviations
  • Contractions: i.e didn't/did not
