Writing an abstract, and language and grammar – day 1: language for ‘saying’ and ‘showing’
Free PreviewIntroduction
There are many synonyms for the verbs ‘say’ and ‘show’ but not all of them are suitable for use in academic writing.
When looking at different verbs that mean ‘say’ and ‘show’, there are subtle differences in meaning – so it’s important to think about how we can use each word.
Here are some useful verbs for ‘saying’ and ‘showing’ that you might see in academic articles. Many of them have multiple meanings in non-academic settings, but here we’ll look at how they’d be used in academic writing.
Firstly, we can use these phrases to talk about things that have been believed or accepted (often for a long time):
- It is well-established that…
- It has long been held that…
- It is well-documented that…
- It is universally acknowledged/accepted that…
Language for ‘saying’
To suggest (meaning: to give an idea for others to think about)

To suggest is often used with the following adverbs to give more information: initially, originally, tentatively, gently, strongly, rightly, wrongly
To report (meaning: to give information about something that has happened – often in an official document produced after careful study of a specific topic)
The researchers reported a sudden fluctuation in results.
To clarify (meaning: to explain something so that it is clearer and easier to understand)

To clarify is often used with the following adverbs to give more information: sufficiently, adequately, fully, precisely
To elucidate (meaning: to explain something and make it clearer – often by providing more information)
To elucidate the role of the nanotechnology in the process, we have provided a short animation.
To argue (meaning: to give reasons explaining why you believe something to be correct or true)

You can use these adverbs with this word to give more information: firmly, repeatedly, strongly.
State (meaning: to say – particularly in a formal way)

You can use these adverbs with this word to give more information: clearly, specifically, consistently, accurately, incorrectly
To declare (meaning: to say something officially or publicly)
The authors have declared that no competing interests exist.
To maintain (meaning: to say that something is true – even when other people do not agree/believe you)
The authors maintained that the work was their own, despite multiple allegations of plagiarism.
To conclude (meaning: to say something is correct/true after considering all the available evidence)
The study concluded that the equipment was too sensitive to be used in the field.
Language for ‘showing’
To demonstrate (meaning: to show something clearly, to show something is true/correct)
In the experiment, we demonstrated the limitations of the current technology.
You can use these adverbs with this word to give more information: consistently, convincingly, successfully, effectively.
To exhibit (meaning: to show a reaction, ability or behaviour)
The test subjects exhibited no reaction to the treatment.
To present (one meaning: to offer something for others to judge or consider)
After presenting their findings at the conference, they were asked to complete two further studies on similar issues.
To present (alternative meaning: used in medical situations – when a patient shows symptoms)
Patients presenting with low blood pressure were not included in the study.
To show (meaning: to give proof that something is correct or true)
Having shown the effects on older patients, the next step is to explore how treatment affects younger patients.
You can use these adverbs with this word to give more information: previously, conclusively, clearly, consistently, repeatedly
To reveal (meaning: to show something that was not previously known)
The study reveals the inconsistencies in patient care across different regions of the same country.
You can use these adverbs with this word to give more information: clearly, plainly, methodically
Language for ‘saying’ and ‘showing’ extract
This extract from an article contains examples of some of the language covered in today’s lesson.
Plasmodesmata play a key role in leaf vein patterning
Linh and Scarpella [5] show that in addition to polarised PIN1-mediated auxin transport within vein cell files, open plasmodesmata enable diffusion between adjacent vein cells. Their study reveals that diffusion of an auxin signal through plasmodesmata is essential to leaf vein patterning in Arabidopsis.
……
Using the callose synthesis mutants (in which spatial variations in plasmodesmal permeability did not occur), auxin application induced veins in significantly fewer cases. Furthermore, applying auxin to wild-type leaves delayed the reduction in plasmodesmal permeability between the veins and non-vasculature tissue, suggesting a coupling between auxin levels and plasmodesmal fluxes.
…..
Having established a crucial role for plasmodesmal diffusion in vein patterning, Linh and Scarpella questioned whether this process is regulated by GNOM (GN), which is a regulator of membrane trafficking and was shown to regulate an undiscovered component of vein patterning in [4]. They observed that regulation of plasmodesmal permeability is defective in gn mutants, and that simultaneous inhibition of the regulation of plasmodesmal permeability, auxin transport, and auxin signalling phenocopies the strong gn mutant. They concluded that GNOM (GN) forms a signalling hub controlling the 3 components of vein formation: auxin signalling, polar transport, and diffusion of an auxin signal through plasmodesmata.
Precisely how the plasmodesmal permeability is regulated during vein formation remains an open question. While the observations using callose synthesis mutants suggest that callose reduces plasmodesmal permeability, the data presented does not ruled out the possibility that differences in plasmodesmal density or structure also contribute to the observed spatial variations in plasmodesmal diffusion.
…..
In summary, Linh and Scarpella [5] elucidate a key mechanistic component of Sach’s Canalisation hypothesis. Their elegant study demonstrates that regulation of plasmodesmata is essential for vein patterning. They conclude that vein patterning occurs through the co-ordinated action of auxin signalling, polar transport, and diffusion of an auxin signal through plasmodesmata, 3 processes that are all regulated by GNOM. How these findings translate to either other plant patterning processes or vein patterning in other species [10] form open and exciting questions for future research.
