Words and Phrases to Avoid in Academic Writing

When you are writing a dissertation, thesis, or research paper, many words and phrases that are acceptable in conversations or informal writing are considered inappropriate in academic writing.

You should try to avoid expressions that are too informal, unsophisticated, vague, exaggerated, or subjective, as well as those that are generally unnecessary or incorrect.

Bear in mind, however, that these guidelines do not apply to text you are directly quoting from your sources (including interviews).

Too informal

Academic writing is generally more formal than the writing we see in non-academic materials (including on websites). It is also more formal than the ways in which we normally speak. The following words and phrases are considered too informal for a dissertation or academic paper.

Informal sentence starts

Some words are acceptable in certain contexts, but become too informal when used at the beginning of a sentence. You can replace these with appropriate transition words or simply remove them from the sentence.

Too vague

Using vague terms makes your writing imprecise and may cause people to interpret it in different ways. Always try to be as specific as possible.

Too exaggerated

Academic writing is usually unadorned and direct. Some adverbs of frequency (such as always and never) and intensifiers (words that create emphasis, such as really) are often too dramatic. They may also not be accurate – you’re making a significant claim when you say something is perfect or never happens.

These terms do sometimes add value, but try to use them sparingly.

Too subjective

Some words and phrases reveal your own bias. For instance, if you state that something will obviously happen, you are indicating that you think the occurrence is obvious – not stating a fact.

Expressing your opinion is appropriate in certain sections of a dissertation and in particular types of academic texts (such as personal statements and reflective or argumentative essays). In most cases, though, take care when using words and phrases such as those below – try to let the facts speak for themselves, or emphasize your point with less biased language.

Generally incorrect

Certain words and phrases are often used incorrectly, even by native speakers of a language. If you’re exposed to such mistakes often enough, you may start to assume they are correct – but it’s important that you don’t let them creep into your writing.

You should also bear in mind that some of these mistakes relate to things we all frequently mishear (for instance, we often think the speaker is saying would of instead of would have).

Other tips

In general, you should also try to avoid using words and phrases that fall into the following categories:

• Jargon (i.e., “insider” terminology that may be difficult for readers from other fields to understand)
• Clichés (i.e., expressions that are heavily overused, such as think outside of the box and at the end of the day)
• Everyday abbreviations (e.g., approx., ASAP, corona, stats, info)
• Slang (e.g., cops, cool)
• Gender-biased language (e.g., firemen, mankind)
• Generally unnecessary (e.g., redundant expressions that do not add meaning, such as compete with each other instead of simply compete)

Exceptions

Reflective reports and personal statements sometimes have a less formal tone. In these types of writing, you may not have to follow these guidelines as strictly. The preface or acknowledgements of a dissertation also often have a less formal and more personal voice than the rest of the document.
