50 Useful Academic Words & Phrases for Research

Like all good writing, writing an academic paper takes a certain level of skill to express your ideas and arguments in a way that is natural and that meets a level of academic sophistication. The terms, expressions, and phrases you use in your research paper must be of an appropriate level to be submitted to academic journals.

Therefore, authors need to know which verbs , nouns , and phrases to apply to create a paper that is not only easy to understand, but which conveys an understanding of academic conventions. Using the correct terminology and usage shows journal editors and fellow researchers that you are a competent writer and thinker, while using non-academic language might make them question your writing ability, as well as your critical reasoning skills.

What are academic words and phrases?

One way to understand what constitutes good academic writing is to read a lot of published research to find patterns of usage in different contexts. However, it may take an author countless hours of reading and might not be the most helpful advice when faced with an upcoming deadline on a manuscript draft.

Briefly, “academic” language includes terms, phrases, expressions, transitions, and sometimes symbols and abbreviations that help the pieces of an academic text fit together. When writing an academic text–whether it is a book report, annotated bibliography, research paper, research poster, lab report, research proposal, thesis, or manuscript for publication–authors must follow academic writing conventions. You can often find handy academic writing tips and guidelines by consulting the style manual of the text you are writing (i.e., APA Style , MLA Style , or Chicago Style ).

However, sometimes it can be helpful to have a list of academic words and expressions like the ones in this article to use as a “cheat sheet” for substituting the better term in a given context.

How to Choose the Best Academic Terms

You can think of writing “academically” as writing in a way that conveys one’s meaning effectively but concisely. For instance, while the term “take a look at” is a perfectly fine way to express an action in everyday English, a term like “analyze” would certainly be more suitable in most academic contexts. It takes up fewer words on the page and is used much more often in published academic papers.

You can use one handy guideline when choosing the most academic term: When faced with a choice between two different terms, use the Latinate version of the term. Here is a brief list of common verbs versus their academic counterparts:

Although this can be a useful tip to help academic authors, it can be difficult to memorize dozens of Latinate verbs. Using an AI paraphrasing tool or proofreading tool can help you instantly find more appropriate academic terms, so consider using such revision tools while you draft to improve your writing.

Top 50 Words and Phrases for Different Sections in a Research Paper

The “Latinate verb rule” is just one tool in your arsenal of academic writing, and there are many more out there.

Write down your thoughts and shred them to relieve anger, researchers say

Writing negative reactions on paper and shredding it or scrunching and throwing in the bin eliminates angry feelings, study finds

Since time immemorial humans have tried to devise anger management techniques.

In ancient Rome, the Stoic philosopher Seneca believed “my anger is likely to do me more harm than your wrong” and offered avoidance tips in his AD45 work De Ira (On Anger).

More modern methods include a workout on the gym punchbag or exercise bike. But the humble paper shredder may be a more effective – and accessible – way to decompress, according to research.

A study in Japan has found that writing down your reaction to a negative incident on a piece of paper and then shredding it, or scrunching it into a ball and throwing it in the bin, gets rid of anger.

“We expected that our method would suppress anger to some extent,” said Nobuyuki Kawai, lead researcher of the study at Nagoya University. “However, we were amazed that anger was eliminated almost entirely.”

The study, published in Scientific Reports on Nature , builds on research on the association between the written word and anger reduction as well as studies showing how interactions with physical objects can control a person’s mood. For instance, those wanting revenge on an ex-partner may burn letters or destroy gifts.

Researchers believe the shredder results may be related to the phenomenon of “backward magical contagion”, which is the belief that actions taken on an object associated with a person can affect the individuals themselves. In this case, getting rid of the negative physical entity, the piece of paper, causes the original emotion to also disappear.

This is a reversal of “magical contagion” or “celebrity contagion” – the belief that the “essence” of an individual can be transferred through their physical possessions.

Fifty student participants were asked to write brief opinions about an important social problem, such as whether smoking in public should be outlawed. Evaluators then deliberately scored the papers low on intelligence, interest, friendliness, logic, and rationality. For good measure, evaluators added insulting comments such as: “I cannot believe an educated person would think like this. I hope this person learns something while at the university.”

The wound-up participants then wrote down their angry thoughts on the negative feedback on a piece of paper. One group was told to either roll up the paper and throw it in a bin or keep it in a file on their desk. A second group was told to shred the paper, or put it in a plastic box.

Anger levels of the individuals who discarded their paper in the bin or shredded it returned to their initial state, while those who retained a hard copy of the paper experienced only a small decrease in their overall anger.

Researchers concluded that “the meaning (interpretation) of disposal plays a critical role” in reducing anger.

“This technique could be applied in the moment by writing down the source of anger as if taking a memo and then throwing it away,” said Kawai.

Along with its practical benefits, this discovery may shed light on the origins of the Japanese cultural tradition known as hakidashisara ( hakidashi sara refers to a dish or plate) at the Hiyoshi shrine in Kiyosu, just outside Nagoya. Hakidashisara is an annual festival where people smash small discs representing things that make them angry. The study’s findings may explain the feeling of relief that participants report after leaving the festival, the paper concluded.

Letter from the co-directors.

A decade ago, the best AI systems in the world were unable to classify objects in images at a human level. AI struggled with language comprehension and could not solve math problems. Today, AI systems routinely exceed human performance on standard benchmarks.

Progress accelerated in 2023. New state-of-the-art systems like GPT-4, Gemini, and Claude 3 are impressively multimodal: They can generate fluent text in dozens of languages, process audio, and even explain memes. As AI has improved, it has increasingly forced its way into our lives. Companies are racing to build AI-based products, and AI is increasingly being used by the general public. But current AI technology still has significant problems. It cannot reliably deal with facts, perform complex reasoning, or explain its conclusions.

AI faces two interrelated futures. First, technology continues to improve and is increasingly used, having major consequences for productivity and employment. It can be put to both good and bad uses. In the second future, the adoption of AI is constrained by the limitations of the technology. Regardless of which future unfolds, governments are increasingly concerned. They are stepping in to encourage the upside, such as funding university R&D and incentivizing private investment. Governments are also aiming to manage the potential downsides, such as impacts on employment, privacy concerns, misinformation, and intellectual property rights.

As AI rapidly evolves, the AI Index aims to help the AI community, policymakers, business leaders, journalists, and the general public navigate this complex landscape. It provides ongoing, objective snapshots tracking several key areas: technical progress in AI capabilities, the community and investments driving AI development and deployment, public opinion on current and potential future impacts, and policy measures taken to stimulate AI innovation while managing its risks and challenges. By comprehensively monitoring the AI ecosystem, the Index serves as an important resource for understanding this transformative technological force.

On the technical front, this year’s AI Index reports that the number of new large language models released worldwide in 2023 doubled over the previous year. Two-thirds were open-source, but the highest-performing models came from industry players with closed systems. Gemini Ultra became the first LLM to reach human-level performance on the Massive Multitask Language Understanding (MMLU) benchmark; performance on the benchmark has improved by 15 percentage points since last year. Additionally, GPT-4 achieved an impressive 0.97 mean win rate score on the comprehensive Holistic Evaluation of Language Models (HELM) benchmark, which includes MMLU among other evaluations.

Although global private investment in AI decreased for the second consecutive year, investment in generative AI skyrocketed. More Fortune 500 earnings calls mentioned AI than ever before, and new studies show that AI tangibly boosts worker productivity. On the policymaking front, global mentions of AI in legislative proceedings have never been higher. U.S. regulators passed more AI-related regulations in 2023 than ever before. Still, many expressed concerns about AI’s ability to generate deepfakes and impact elections. The public became more aware of AI, and studies suggest that they responded with nervousness.

Key facts about the abortion debate in America

The U.S. Supreme Court’s June 2022 ruling to overturn Roe v. Wade – the decision that had guaranteed a constitutional right to an abortion for nearly 50 years – has shifted the legal battle over abortion to the states, with some prohibiting the procedure and others moving to safeguard it.

As the nation’s post-Roe chapter begins, here are key facts about Americans’ views on abortion, based on two Pew Research Center polls: one conducted from June 25-July 4 , just after this year’s high court ruling, and one conducted in March , before an earlier leaked draft of the opinion became public.

This analysis primarily draws from two Pew Research Center surveys, one surveying 10,441 U.S. adults conducted March 7-13, 2022, and another surveying 6,174 U.S. adults conducted June 27-July 4, 2022. Here are the questions used for the March survey , along with responses, and the questions used for the survey from June and July , along with responses.

Everyone who took part in these surveys is a member of the Center’s American Trends Panel (ATP), an online survey panel that is recruited through national, random sampling of residential addresses. This way nearly all U.S. adults have a chance of selection. The survey is weighted to be representative of the U.S. adult population by gender, race, ethnicity, partisan affiliation, education and other categories.  Read more about the ATP’s methodology .

A majority of the U.S. public disapproves of the Supreme Court’s decision to overturn Roe. About six-in-ten adults (57%) disapprove of the court’s decision that the U.S. Constitution does not guarantee a right to abortion and that abortion laws can be set by states, including 43% who strongly disapprove, according to the summer survey. About four-in-ten (41%) approve, including 25% who strongly approve.

About eight-in-ten Democrats and Democratic-leaning independents (82%) disapprove of the court’s decision, including nearly two-thirds (66%) who strongly disapprove. Most Republicans and GOP leaners (70%) approve , including 48% who strongly approve.

Most women (62%) disapprove of the decision to end the federal right to an abortion. More than twice as many women strongly disapprove of the court’s decision (47%) as strongly approve of it (21%). Opinion among men is more divided: 52% disapprove (37% strongly), while 47% approve (28% strongly).

About six-in-ten Americans (62%) say abortion should be legal in all or most cases, according to the summer survey – little changed since the March survey conducted just before the ruling. That includes 29% of Americans who say it should be legal in all cases and 33% who say it should be legal in most cases. About a third of U.S. adults (36%) say abortion should be illegal in all (8%) or most (28%) cases.

Generally, Americans’ views of whether abortion should be legal remained relatively unchanged in the past few years , though support fluctuated somewhat in previous decades.

Relatively few Americans take an absolutist view on the legality of abortion – either supporting or opposing it at all times, regardless of circumstances. The March survey found that support or opposition to abortion varies substantially depending on such circumstances as when an abortion takes place during a pregnancy, whether the pregnancy is life-threatening or whether a baby would have severe health problems.

While Republicans’ and Democrats’ views on the legality of abortion have long differed, the 46 percentage point partisan gap today is considerably larger than it was in the recent past, according to the survey conducted after the court’s ruling. The wider gap has been largely driven by Democrats: Today, 84% of Democrats say abortion should be legal in all or most cases, up from 72% in 2016 and 63% in 2007. Republicans’ views have shown far less change over time: Currently, 38% of Republicans say abortion should be legal in all or most cases, nearly identical to the 39% who said this in 2007.

However, the partisan divisions over whether abortion should generally be legal tell only part of the story. According to the March survey, sizable shares of Democrats favor restrictions on abortion under certain circumstances, while majorities of Republicans favor abortion being legal in some situations , such as in cases of rape or when the pregnancy is life-threatening.

There are wide religious divides in views of whether abortion should be legal , the summer survey found. An overwhelming share of religiously unaffiliated adults (83%) say abortion should be legal in all or most cases, as do six-in-ten Catholics. Protestants are divided in their views: 48% say it should be legal in all or most cases, while 50% say it should be illegal in all or most cases. Majorities of Black Protestants (71%) and White non-evangelical Protestants (61%) take the position that abortion should be legal in all or most cases, while about three-quarters of White evangelicals (73%) say it should be illegal in all (20%) or most cases (53%).

In the March survey, 72% of White evangelicals said that the statement “human life begins at conception, so a fetus is a person with rights” reflected their views extremely or very well . That’s much greater than the share of White non-evangelical Protestants (32%), Black Protestants (38%) and Catholics (44%) who said the same. Overall, 38% of Americans said that statement matched their views extremely or very well.

Catholics, meanwhile, are divided along religious and political lines in their attitudes about abortion, according to the same survey. Catholics who attend Mass regularly are among the country’s strongest opponents of abortion being legal, and they are also more likely than those who attend less frequently to believe that life begins at conception and that a fetus has rights. Catholic Republicans, meanwhile, are far more conservative on a range of abortion questions than are Catholic Democrats.

Women (66%) are more likely than men (57%) to say abortion should be legal in most or all cases, according to the survey conducted after the court’s ruling.

More than half of U.S. adults – including 60% of women and 51% of men – said in March that women should have a greater say than men in setting abortion policy . Just 3% of U.S. adults said men should have more influence over abortion policy than women, with the remainder (39%) saying women and men should have equal say.

The March survey also found that by some measures, women report being closer to the abortion issue than men . For example, women were more likely than men to say they had given “a lot” of thought to issues around abortion prior to taking the survey (40% vs. 30%). They were also considerably more likely than men to say they personally knew someone (such as a close friend, family member or themselves) who had had an abortion (66% vs. 51%) – a gender gap that was evident across age groups, political parties and religious groups.

Relatively few Americans view the morality of abortion in stark terms , the March survey found. Overall, just 7% of all U.S. adults say having an abortion is morally acceptable in all cases, and 13% say it is morally wrong in all cases. A third say that having an abortion is morally wrong in most cases, while about a quarter (24%) say it is morally acceptable in most cases. An additional 21% do not consider having an abortion a moral issue.

Among Republicans, most (68%) say that having an abortion is morally wrong either in most (48%) or all cases (20%). Only about three-in-ten Democrats (29%) hold a similar view. Instead, about four-in-ten Democrats say having an abortion is morally  acceptable  in most (32%) or all (11%) cases, while an additional 28% say it is not a moral issue. 

White evangelical Protestants overwhelmingly say having an abortion is morally wrong in most (51%) or all cases (30%). A slim majority of Catholics (53%) also view having an abortion as morally wrong, but many also say it is morally acceptable in most (24%) or all cases (4%), or that it is not a moral issue (17%). Among religiously unaffiliated Americans, about three-quarters see having an abortion as morally acceptable (45%) or not a moral issue (32%).

• Religion & Abortion

What the data says about abortion in the U.S.

Support for legal abortion is widespread in many countries, especially in europe, nearly a year after roe’s demise, americans’ views of abortion access increasingly vary by where they live, by more than two-to-one, americans say medication abortion should be legal in their state, most latinos say democrats care about them and work hard for their vote, far fewer say so of gop, most popular.

Living Better

Rise and grind working late, volatile hours may lead to depression, illness by 50.

Working late nights and variable schedules when you're young is linked with poor health and depression at 50, a new study finds.

Feeling burned out and looking for reasons to work less? A new study shows that working nights and volatile schedules in young adulthood can leave you vulnerable to depression and poor health in middle age.

The research examined the work schedules and sleep patterns of more than 7,000 Americans interviewed over three decades, from the ages of 22 through 50. To the surprise of the study's author, NYU Silver School of Social Work professor Wen-Jui Han , only one-quarter of the participants worked exclusively traditional daytime hours.

The remainder – three-quarters of the sample of American workers born in the 1960s – worked variable hours. Those with more volatile work schedules, including night hours and rotating shifts, reported less sleep and a greater likelihood of poor health and depression at age 50 than those with more stable schedules and daytime hours.

"Our work now is making us sick and poor," Han said in a Zoom interview. "Work is supposed to allow us to accumulate resources. But, for a lot of people, their work doesn't allow them to do so. They actually become more and more miserable over time."

Han would like her research — published last week in PLOS One — to prompt conversations about ways to "provide resources to support people to have a happy and healthy life when they're physically exhausted and emotionally drained because of their work."

Want to stress less in 2024 a new book offers '5 resets' to tame toxic stress.

She was one of those employees. In her 40s, when Han was up for tenure, she worked 16-hour days, taking time off only to eat and sleep, though not sleeping nearly enough. Her doctor warned her that her physical condition appeared more like that of a woman in her 60s.

She was overworking like many young professionals who have embraced hustle culture and work around the clock.

"We can say they voluntarily want to work long hours, but in reality, it's not about voluntarily working long hours," Han said. "They sense that the culture of their work demands that they work long hours, or they may get penalized."

She says the participants in her study who sacrificed sleep to earn a living, suffered depression and poor health, she said. "When our work becomes a daily stressor, these are the kind of health consequences you may expect to see 30 years down the road."

Black men and women and workers with limited educations disproportionately shouldered the burden of night shifts, volatile work schedules and sleep deprivation, the study shows.

White college-educated women with stable daytime work reported an average of six more hours of sleep a week than Black men who had not completed high school and who worked variable hours for most of their lives, Han's study found.

And Black women who did not complete high school and switched from regular daytime hours to volatile employment in their 30s were four times more likely to report poor health than white college-educated men with stable and standard daytime work lives.

The study shows a relationship between working nights and rotating shifts with poor sleep and poor health, but it cannot prove one caused the other. That said, the U.S. Centers for Disease Control and Prevention links insufficient sleep with chronic diseases, such as diabetes, heart disease and obesity, and African Americans are more likely than whites to suffer from these diseases.

How much a person needs to sleep to remain healthy depends upon age, but the American Academy of Sleep Medicine and the Sleep Research Society recommend that adults between 18 and 60 years old get at least seven hours of shut-eye a night.

Dr. Alyson Myers appreciated the new study's focus on the connection between work schedules, sleep and poor health.

The study findings confirmed what she sees in many of her diabetes patients, who often get no more than five hours of sleep after they work night shifts. She counsels them to try to switch to days, and when they do, their health improves, the endocrinologist and professor at the Albert Einstein College of Medicine said.

Prior research has shown that sleep, diet and social habits required to work nights and rotating shifts, can increase the risk of developing diabetes. In 2019, Blacks were twice as likely as whites to die of diabetes , according to the U.S. Department of Health and Human Services.

"Poor sleep is a risk factor for diabetes that very often we do not talk about," said Myers, who was not involved in the study. "One of the things that I have to preach to my patients about is that working nights, and if you get only four or five or less hours of sleep, that's going to increase your risk of diabetes and also worsen your glycemic control."

One patient was angry with her when he followed her advice, switched from working nights to days and as a result had to contend with commute traffic. "But," she said in a Zoom interview, "we actually got better control of his blood sugar when he switched to working the day shift."

About 16% of American workers were employed outside of daytime hours in 2019, according to the U.S. Bureau of Labor Statistics.

Many of the participants in Hans' study who had volatile work schedules tended to have part-time jobs, in some cases multiple part-time jobs. "Unfortunately," Myers said, "the trend for a lot of these people is that they have to work more than one job to survive."

Stanford Medicine-led study identifies novel target for epilepsy treatment

Researchers find that a little-understood part of the brain appears to be involved in starting seizures and keeping them going.

April 17, 2024 - By Kimberlee D'Ardenne

Removing part of the brain’s temporal lobe is the only treatment available to the millions of people with a form of epilepsy that medications often don’t alleviate. But even that approach fails a third of the time.

A new study from Stanford Medicine researchers and their colleagues offers an explanation and suggests a more effective approach to treatment. They found that a previously overlooked region of the hippocampus, the fasciola cinereum, appears to be involved in instigating and propagating seizures. Removing or inhibiting the fasciola cinereum may help those patients who don’t find relief after surgery.

“The hippocampus is the best studied part of the brain by far, but there is shockingly little known about the fasciola cinereum,” said Ivan Soltesz , PhD, the James R. Doty Professor in Neurosurgery and Neurosciences and a senior author on the study. “This relatively small region was consistently involved in seizure activity in mice and in people undergoing pre-surgical electrical recordings. Our findings suggest that all patients with drug-resistant temporal lobe epilepsy should have depth electrodes placed in the fasciola cinereum as part of the surgery planning process.”

The work was published April 17 in Nature Medicine . Soltesz and Vivek Buch , MD, the Christina and Hamid Moghadam Faculty Scholar as well as the surgical director of the Stanford Comprehensive Epilepsy Center , are co-senior authors.

A tale of a tail

Worldwide, 65 million people live with epilepsy. Tens of millions have mesial temporal lobe epilepsy, with seizures originating, in part, from the amygdala, an almond-shaped structure involved in processing emotions, and the hippocampus, a region necessary for forming memories. When people with mesial temporal lobe epilepsy of just one hemisphere do not respond to anti-seizure drug therapies, the standard of care is surgery. In these procedures, the amygdala and most of the hippocampus in one hemisphere are either surgically removed or ablated, a technique that involves using a laser to heat up and destroy tissue. Because of the symmetry of the temporal lobe — both hemispheres of the brain have an amygdala and hippocampus — people who have these surgeries usually have minimal side effects, according to the researchers.

Ivan Soltesz

Before performing the surgery, physicians need to identify the brain tissue responsible for seizure activity. They do this by placing electrodes in areas of the brain suspected of starting or propagating seizures and taking recordings from the electrodes. This process, called stereoelectroencephalography, or sEEG, lets them map where in the brain seizure activity happens.

Though the amygdala and its next-door neighbor the hippocampus are common locations for sEEG recordings, the electrodes are typically placed in only the anterior and middle regions of the hippocampus. The human hippocampus, located deep in each hemisphere of the brain near the level of the ear, looks like a sea horse lying on its side, with its head pointing toward the front of the brain. sEEG electrodes are commonly placed in the anterior and medial regions, corresponding to the head, body and the beginnings of the tail of the sea horse.

The idea to record from the fasciola cinereum — the far tip of the sea horse’s tail — in patients with epilepsy undergoing sEEG for surgical planning first formed about three years ago, when Ryan Jamiolkowski , MD, PhD, co-lead author of the study and a resident in neurosurgery, joined the Soltesz lab.

At the time, Quynh-Anh Nguyen, PhD, co-lead author on the study and former postdoctoral scholar in the Soltesz lab who is now at Vanderbilt University, was screening for the hippocampal neurons that were active during seizures in mice. Unexpectedly, Nguyen discovered that neurons in a posterior region of the hippocampus, the fasciola cinereum, were involved in seizures.

Jamiolkowski and the research team used optogenetic techniques to test whether the fasciola cinereum could be a target for epilepsy interventions. The neurons in the fasciola cinereum were made to contain special proteins capable of shutting down neuronal activity when exposed to blue light. When electrical recordings from the hippocampus showed seizure activity, the researchers shined blue light onto the fasciola cinereum, shortening the duration of seizures in mice.

Recording from the human hippocampus tail

To understand the fasciola cinereum’s role in seizure activity in humans, Jamiolkowski and Buch recorded from the small region in six patients. All were undergoing sEEG to identify the source of their seizures in preparation for future surgeries to cure their epilepsy. The fasciola cinereum contributed recorded seizures in all six patients, including some episodes in which the head and body regions of the hippocampus were quiet.

Ryan Jamiolkowski

One of the patients with mesial temporal lobe epilepsy of the left hemisphere had already undergone laser ablation of the amygdala and anterior and middle regions of the hippocampus. The patient continued having seizures, and follow-up sEEG showed that the only part of the hippocampus that remained, the fasciola cinereum, was involved in all recorded seizures. The patient underwent a second surgical ablation that removed almost all of the fasciola cinereum, and the frequency of the seizures decreased by 83%, from one to two each month to once every three months.

The researchers said that patients whose seizures involve the fasciola cinereum may need to undergo two surgeries because of the shape of the hippocampus.

“The hippocampus curves like a banana, and the optical fiber used for laser ablation is a straight line. Reaching anterior and posterior regions requires different trajectories that are not currently feasible to combine into one procedure. The results of our study do not challenge the importance of ablating the amygdala and anterior hippocampus but suggest considering a second ablation targeting the posterior hippocampal tail for the patients whose seizures recur,” Jamiolkowski said.

Three of the patients had bilateral involvement of the mesial temporal lobe, which means the amygdala and hippocampus in both the right and left hemisphere showed seizure activity. Because new memories cannot be formed without at least one intact hippocampus, these patients instead received responsive neurostimulation from a device that detects and interrupts seizure activity. However, most responsive neurostimulation units can be configured to target only the anterior regions of the hippocampus on both sides of the brain. The findings from this study suggest that a more personalized approach that also allows the device to monitor and interrupt seizure activity in the posterior hippocampal tail region might be more beneficial to patients.

“Because one-third of patients — a high percentage — do not get seizure freedom from surgery, we should be putting sEEG electrodes in the fasciola cinereum in all temporal lobe epilepsy patients; seizure activity in this region could be a reason why these surgeries sometimes fail,” Jamiolkowski added. “Knowing which patients have seizures involving the fasciola cinereum would let us target it with either ablation or neurostimulation and help us treat patients better than a one-size-fits all approach.”

A researcher from Cambridge University contributed to the study.
