Complicated sentences

Long, complicated sentences1 can be difficult to understand. To fix a complicated sentence, you usually cannot simply break the sentence into two; you need to look critically at the structure. Follow these steps to fix it.

1. Choose one main structure: subject-verb-object

Notice how many different kinds of phrases you use, especially introductory phrases, relative clauses, and prepositional phrases. Each phrase can be considered a different "moving part" and must be connected clearly to the phrases around it. Minimize the number of "moving parts" in the sentence to make it clearer.

When the main information is in a sub-sentence, move it to the main sentence:

These analyses show that most patients would benefit from the follow-up protocol, no matter the initial severity of the disease.

Most patients would benefit from the follow-up protocol, no matter the initial severity of the disease.

Reduce the number of prepositional phrases and relative clauses:

This in vivo cell-based platform produces recombinant proteins at large scales and high yields by DNA transfection in host cells.

This in vivo cell-based platform uses DNA transfection in host cells to produce recombinant proteins at large scales and high yields.

2. Put the key content words in the topic position

Make sure the topic position contains given information and decide which verb should go next to that subject.

Don't put "researchers" or "past studies" in the topic position unless your research is about those researchers or studies:

Past studies have found that women with a BRCA mutation have an increased risk of certain types of cancer.

Women with a BRCA mutation have an increased risk of certain types of cancer (reference).

3. Choose a precise verb

Find the zombie nouns and empty verbs and change them back into clear verbs.

4. Create parallelism

If your sentence has multiple parts, are they structured in the same way?

To learn more about parallelism, read the parallelism page.

5. Remove redundancy

You may be redundant when you use multiple words with a similar meaning:

My assessment is centered on the suitability of the research methodology that is employed in the projects for answering the research questions posed, primarily analysing the explicitness and delineation of the methodological choices.

I will assess how well the chosen research methodology is able to answer the research questions, focusing on the explicitness and delineation of the methodological choices.

You may use vague or empty words:

Therefore, the aim of this review is to determine what we can learn from the three strategies: recombinant protein expression, cell-free protein synthesis using lysates, and cell-free protein synthesis using purified proteins.

In this review, we determine what we can learn from the three strategies: recombinant protein expression, cell-free protein synthesis using lysates, and cell-free protein synthesis using purified proteins.
OR

How does ReallyWrite determine complicated sentences?

ReallyWrite uses an algorithm called the Automated Readability Index to determine which sentences are complicated. The ARI is determined based on the length of the sentence and the difficulty of individual words.

What the score means

The ARI score corresponds to the US grade level required to understand that sentence.

The US has 12 grade levels before university. So if the score is 12, then a reader needs to have finished high school (secondary school) to understand that sentence. If the score is 16, then they need to have a bachelor's degree before they can understand it.

The ReallyWrite Editor marks sentences as complicated if they have a readability score of 14-19 and as very complicated if they have a score of 20 or higher.

Footnotes

  1. Not all long sentences are complicated. If your long sentence has a clear structure, it can still be easy to read.
