Definitions in: English- 1accommodateverbformal
to provide room or facilities for something, or to change so as to make room for it
Two senses, and the academic one is not the hotel one. In argument it means make room for or take account of: a theory accommodates awkward evidence, a timetable accommodates part-time students. It is also among the most misspelled words in English (double c, double m). The noun 'accommodation' meaning lodging is uncountable in British English, while American English says 'accommodations'.
The new lecture hall accommodates four hundred students.
The new lecture hall has seats for four hundred people.
- 2analogynounformal
a comparison between two things that are alike in some way, used to explain one of them
The pattern is 'an analogy between A and B' or 'by analogy with', never 'analogy of'. You draw or make an analogy. The adjective is 'analogous', which takes 'to' and is pronounced with a hard g; do not confuse it with 'analogue', a signal or a counterpart. Arguing from analogy is legitimate but weak, and 'false analogy' is a named fallacy.
The author draws an analogy between the brain and a telephone exchange.
The writer explains how the brain works by comparing it to a telephone exchange.
- 3anticipateverbneutralformal
to expect something and prepare or act in advance because of it
Stronger than 'expect': you anticipate something and act on it in advance. The grammar trips learners up because it takes a that-clause or an -ing form but never a to-infinitive, so 'we anticipate to find' is wrong and 'we anticipate finding' is right. In a proposal, 'anticipated outcomes' promises you have planned for them; if you only mean 'we think', write 'expect'.
The study anticipated a fall in enrolment and planned for it.
The researchers expected fewer students and made arrangements ahead of time.
- 4assureverbformal
to tell someone confidently that something is true, so as to remove their doubt
One of a confusable trio. You assure a PERSON that something is true, you ensure a RESULT, and you insure property against loss. Most sentences in which students write 'assure' actually need 'ensure'. In British English 'assurance' also names life insurance, and 'quality assurance' is the fixed term for checking that standards are met.
The authors assure readers that all identifiers were destroyed.
The writers promise readers that every identifying detail was deleted.
- 5attainverbformal
to reach or achieve a level, standard or goal, usually after effort
A formal 'reach', used for standards, levels, qualifications and ages, not for places: you reach a station, you do not attain it. British education writing leans on the noun, so 'attainment', 'levels of attainment' and 'the attainment gap' are the phrases to recognise in policy documents. 'Attainable' means realistically reachable, which is the whole point of the word.
Only a third of pupils attained the expected reading level.
Just one pupil in three reached the reading standard set for them.
- 6behalfnounformal
It survives only inside a phrase: 'on behalf of someone' or 'on someone's behalf', meaning as their representative or in their interest. It has no plural and never stands alone, so 'on the behalf' is wrong; American English also keeps 'in behalf of', traditionally for someone's benefit rather than as their representative. Keep it apart from 'on the part of', which attributes an action to someone rather than doing it for them.
The award was accepted on behalf of the whole department.
Someone took the prize as a representative of the entire department.
- 7bulknounformal
the main or largest part of something, or its large size or mass
'The bulk of' means the majority, and the verb after it follows the sense: the bulk of the money was, the bulk of the students were. It also means sheer mass, which gives 'in bulk', 'bulk buying' and the adjective 'bulky'. In a thesis 'the majority of' is the safer choice, because 'the bulk of the evidence' sounds like an estimate rather than a count.
The bulk of the sample came from two urban schools.
Most of the people studied came from a pair of city schools.
- 8ceaseverbformal
to stop doing something, or to come to an end
The formal 'stop'. It takes both patterns with a slight difference: 'cease trading' is about an activity ending, 'cease to exist' about a state ending. The noun is irregular and worth memorising, because it is 'cessation', not 'ceasement'. Everyday English prefers 'stop', so 'cease' in a sentence signals a legal, official or literary register.
Funding for the programme ceased in 2019.
Money for the programme stopped arriving in 2019.
- 9coherentadjectiveformal
logically connected and easy to follow as a whole
The examiner's word: the IELTS writing criteria are headed 'Coherence and Cohesion', and the two are not the same. Coherence is whether the whole argument hangs together and can be followed; cohesion is whether the sentences are linked by devices such as 'however' and 'therefore'. A text can be cohesive without being coherent. Applied to a policy it means the parts do not contradict one another.
The essay is well researched but not coherent.
The essay rests on wide reading, yet its parts do not hold together.
- 10coincideverbformal
to happen at the same time as something else, or to agree or match
Always with 'with', in two senses: to happen at the same time, and to agree or match. The trap is the noun. 'Coincidence' adds a claim that the timing was mere chance, which the verb does not make, so 'the two peaks coincide' reports timing while 'it was a coincidence' denies a connection. Neither is a claim of cause, and neither is the same as 'correlate'.
The rise in cases coincided with the reopening of schools.
Infections went up at the same time that schools opened again.
- 11commenceverbformal
to begin or start, especially in formal or official language
Begin, in the register of statutes, contracts and ceremonies: proceedings commence, a course commences in October. Reaching for it in ordinary prose is a common way to make writing sound stiff, and 'the experiment commenced' is no clearer than 'the experiment began'. Note the American noun 'commencement', which means a graduation ceremony rather than a beginning.
Data collection commenced in September 2021.
The team began gathering information in September 2021.
- 12compatibleadjectiveneutral
able to exist or be used together without conflict
Always 'compatible with', never 'compatible to'. It has a technical home (compatible with Windows) and an argumentative one, and the second is worth care: saying a result is compatible with a hypothesis claims only that it does not contradict it, which is much weaker than saying it supports it. Negative 'incompatible', noun 'compatibility'.
The findings are compatible with both explanations.
Neither of the two accounts is ruled out by what the study produced.
- 13concurrentadjectiveformaltechnical
happening or existing at the same time as something else
Learn it against 'consecutive', because the pair carries real consequences. Concurrent things run at the same time; consecutive things run one after another, so concurrent prison sentences of four years mean four years in total and consecutive ones mean much longer. In test design 'concurrent validity' means the new measure agrees with an established one taken at the same time.
Two concurrent trials tested the same drug in different countries.
A pair of studies ran side by side, testing one drug in two countries.
- 14confineverbformal
to keep something within limits, or to keep someone shut in a restricted place
In academic prose it usually marks scope: this paper confines itself to England, the analysis is confined to adults. The pattern is 'confine X to Y', often reflexively. Physically it means to shut in, which gives 'a confined space' and 'confinement'. The plural noun 'confines' means boundaries, as in 'within the confines of the study'.
This chapter confines itself to secondary schools in Wales.
This chapter deals only with the secondary sector in Wales.
- 15controversynounneutral
a public disagreement in which many people argue strongly on opposing sides
A public dispute in which many people take sides, not merely a disagreement between two researchers. A controversy is sparked, provoked or fuelled, and a figure can be at the centre of one. The word is famous for its two stresses, on the first syllable in American English and often on the second in British English, and both are accepted. Adjective 'controversial'.
The trial's design provoked considerable controversy.
The way the trial was set up caused a great deal of public argument.
- 16conversenounformal
the reversed or opposite form of a statement
Three words wearing one spelling. The noun 'the converse' is the statement with its terms reversed, and in logic the converse of 'if A then B' is 'if B then A', which need not be true. The adjective means opposite. The verb, stressed on the second syllable, means to talk. The one you will actually write is the linker 'conversely', which introduces the reversed case.
The converse does not hold: not every rise in income lowers crime.
The reversed claim is false, since higher earnings do not always cut crime.
- 17devicenounneutral
an object made for a particular purpose, or a technique used to achieve an effect
The noun is spelled with c and the verb 'devise' with s, exactly as in advice and advise, and the pair is a reliable source of marks lost: you devise a method, you use a device. Beyond hardware it names a technique, so a rhetorical or literary device is a deliberate move by a writer. The idiom 'left to their own devices' means without supervision.
Each participant wore a small tracking device for a week.
Everyone in the study carried a small tracker for seven days.
- 18devoteverbneutral
to give time, money, space or effort entirely to one purpose
'Devote X to Y', where X is time, money, space or effort, and the passive is the form academic writing uses most: the second chapter is devoted to method. Keep the family apart. 'Devoted' as an adjective means loyal or loving, and the noun 'devotion' is emotional or religious, so 'the devotion of three pages to sampling' reads oddly where 'three pages are devoted to sampling' is normal.
The authors devote a whole chapter to sampling.
The writers give an entire chapter over to how they chose their sample.
- 19diminishverbformal
to become smaller or less important, or to make something so
Works both ways round: an effect diminishes, and something diminishes an effect. The participle carries two fixed terms worth knowing, 'diminishing returns' in economics and 'diminished responsibility' in law. The noun is 'diminution', rare and awkward enough that most writers rephrase with a verb. It implies a gradual decline, so it does not fit a sudden collapse.
The effect diminishes as the sample grows larger.
The result grows weaker the more people are included.
- 20distortverbneutral
to change something so that it is no longer accurate or true to its original form
The standard verb for what a bias does to a result: outliers distort the mean, leading questions distort the answers. It always carries a criticism, since something true has been bent out of shape, so it is not a neutral substitute for 'affect'. The noun 'distortion' is countable and can be listed, as in 'three sources of distortion'.
A handful of extreme values distorted the average.
A few very high figures pulled the mean away from the truth.
- 21durationnounneutralformal
the length of time that something lasts
A measured length of time, never a point in it, so 'at the duration' is impossible and 'for the duration of' is the usual phrase. It pairs with 'period', which names a stretch of time rather than measuring it. Medicine and psychology use it constantly: duration of symptoms, duration of exposure, mean duration of treatment.
The average duration of treatment was eleven weeks.
Care lasted eleven weeks on average.
- 22erodeverbneutral
to wear something away gradually, whether rock or something abstract such as trust
Geological in origin and figurative in use: what academic writing erodes is trust, confidence, support, rights or margins. The word builds in slowness and one direction, so it belongs with 'gradually' and 'steadily' rather than with 'suddenly', and nothing is eroded overnight. The noun 'erosion' is the form you will meet most, as in 'the erosion of civil liberties'.
Repeated scandals have eroded public trust in the regulator.
One scandal after another has slowly worn away people's faith in the regulator.
- 23ethicnounformal
a principle or set of principles about what is morally right
The singular names a guiding principle, as in 'a work ethic' or 'a professional ethic'. The plural does double duty and changes its verb accordingly: as the branch of philosophy it is singular ('ethics is concerned with'), as a person's code it is plural ('his ethics were questioned'). Every dissertation also needs the adjective in its administrative sense, 'ethical approval'.
The company promotes a strong work ethic.
The firm encourages the belief that hard work is right and important.
- 24formatnounneutral
the way something is arranged or presented, or to arrange it in that way
Noun and verb. As a noun it is the shape something is presented in, from the format of an exam to a file format; as a verb it means to arrange to a specification, and in computing it also means to wipe a disk clean, which is why 'format the drive' is an alarming instruction. Spelling: the t doubles, giving formatted and formatting. It shares the Latin forma with 'formation' and 'formula', though each has settled into a quite separate use.
The exam keeps the same format in every session.
The paper is arranged the same way each time it is sat.
- 25foundverbneutralformal
to establish an organisation or institution, or to base something on a principle or evidence
Not the past tense of 'find'. This is a separate verb, found, founded, founded, meaning to establish: a college is founded in 1451, whereas a key is found under a chair. Read the sentence for the pattern, because 'the society was founded' can only be this verb. Its second use is 'be founded on', meaning be based on. The noun 'foundation' is its own headword in sublist 7.
The college was founded by a group of merchants in 1451.
A group of traders set the college up in 1451.
- 26inherentadjectiveformal
existing as a natural and permanent part of something, and so impossible to remove
Takes 'in', and means belonging to something by its nature, which is why it implies the quality cannot be removed by better design: the risks inherent in surgery stay there however careful the surgeon. That makes it a strong claim, so do not use it where you only mean 'common' or 'frequent'. Near neighbours are 'intrinsic' and 'built-in'; 'inherit' is a different word.
Every study of this design carries inherent sampling risks.
Dangers in choosing the sample come with any study built this way and cannot be removed.
- 27insightnounneutralformal
a clear and deep understanding of something complicated
The preposition is always 'into': an insight into how nurses ration time, never 'insight of' or 'insight about'. It works countably and uncountably, and it collocates with provide, offer, gain and valuable. Beware its use as filler, since 'provides insights into' frequently means no more than 'tells us a little about', and examiners notice the difference.
The interviews offer an insight into how nurses ration their time.
The interviews let the reader understand clearly how nurses divide up their hours.
- 28integraladjectiveformaltechnical
necessary to make something complete, or, in mathematics, the result of integrating a function
Two words in one spelling, and sound will not separate them: the first syllable carries the stress in ordinary use for both, so only the grammar tells you which one you have. The adjective means forming a necessary part of a whole and takes 'to': fieldwork is integral to the degree. The mathematical noun names the result of integration, and calculus texts speak of the definite integral between two limits. Neither means 'integrated' (joined up) or 'integrity' (honesty, or wholeness).
Fieldwork is integral to the degree, not an optional extra.
The degree would be incomplete without fieldwork, and it cannot be skipped.
- 29intermediateadjectiveneutral
positioned between two levels, stages or points
Language courses give learners the level sense first (intermediate, upper intermediate), but in science it names a stage partway through a process: an intermediate step, an intermediate compound, an intermediate host. Keep it away from 'intermediary', which is a person or body acting between two sides, so a broker is an intermediary and not an intermediate.
The course sits at an intermediate level between beginner and advanced.
The class lies halfway between the starting and the highest stages.
- 30manualadjectiveneutral
done by hand rather than automatically, or a book of instructions
As an adjective it means done by hand, which in research writing usually means done by a person rather than by software: manual coding, manual checking, manual data entry. As a noun it is the book of instructions. The Latin root for hand also gives 'manuscript' and 'manufacture', which is a useful hook. The adverb 'manually' is what you write when contrasting with automation.
Two researchers carried out the manual coding of every transcript.
Two people labelled each interview by hand rather than with software.
- 31matureadjectiveneutral
fully developed or fully grown, or to become fully developed
Fully developed, of a person, an organism, a technology or an idea. British universities use it in an administrative sense every applicant meets: a mature student is one who begins a degree later than the usual age, typically over 21, and it says nothing about behaviour. As a verb it also has a financial sense, since a bond matures when it becomes payable. Noun 'maturity'.
Almost a third of the intake are mature students returning to study.
Nearly one entrant in three is an older beginner coming back to education.
- 32mediateverbformaltechnical
to act between opposing sides to settle a dispute, or to carry an effect from one variable to another
To mediate, in the everyday sense, is to act between two sides in a dispute, and it takes 'between'. Statistics gives it a second life that examiners test: a mediating variable carries the effect from cause to outcome, whereas a moderating variable changes how strong that effect is. Confusing mediator with moderator changes what a model claims. 'Immediate' is this word negated, in- plus mediatus, meaning with nothing in between.
The union asked an outside body to mediate between staff and management.
The union asked an outside group to help the two sides reach agreement.
- 33mediumnounneutral
a means by which something is communicated or done, or a middle level or size
The plural is the whole lesson. For a means of communication it is 'media', which is a separate headword in sublist 7 and is now usually treated as a singular mass noun ('the media is'). For a size or level the plural is 'mediums'. Biology keeps the Latin plural too, since cells grow in a culture medium and in several media. 'Medium of instruction' names the language a school teaches in.
Radio was the dominant medium for political speech in the 1930s.
Broadcasting by wireless was the leading channel for political talk in the 1930s.
- 34militaryadjectiveneutral
relating to armed forces or soldiers, or the armed forces taken as a whole
Mostly an adjective (military spending, military service, a military coup), but with 'the' it also works as a collective noun, and British usage allows either a singular or a plural verb after it. The plural 'militaries' does exist and is ordinary in comparative politics, as in the militaries of the region, but the singular with 'the' is what you will write far more often. Related words are not synonyms: a militia is an unofficial armed force, and 'militant' describes an attitude rather than an army.
Military spending rose sharply after the 2014 crisis.
Money going to the armed forces climbed steeply after the 2014 crisis.
- 35minimaladjectiveneutralformal
very small in amount or effect, or as small as it can be
Set it against 'minimum', which is a separate headword in sublist 6. Minimal is an adjective of degree meaning very small in amount or effect: minimal risk, minimal disruption. Minimum names a floor and is used before nouns as a fixed pairing: minimum wage, minimum age, a minimum of three. So 'minimal wage' and 'minimum difference' are both errors when what you mean is the other one.
The change had a minimal effect on waiting times.
Waiting times barely moved after the change.
- 36mutualadjectiveneutral
felt or done equally by two or more parties towards each other, or shared in common
Felt or done by each side towards the other: mutual respect, mutual benefit, mutual recognition. Older handbooks condemned 'a mutual friend' for 'a friend in common', but that use is now standard. The phrase to learn for argument and statistics is 'mutually exclusive', meaning two outcomes that cannot both occur, which is quite different from two claims that merely disagree.
The agreement rests on mutual recognition of qualifications.
Each country accepts the other's certificates, and the deal depends on it.
- 37normnounformaltechnical
a standard of behaviour that a group expects, or a typical benchmark value
Do not read it as a shortening of 'normal', which is the adjective and a separate headword in sublist 2. A norm is a standard: either a rule of behaviour a group expects, which is how sociology uses it, or a benchmark score for a population, which is how testing uses it. So write 'social norms', not 'social normals', and 'it is normal', not 'it is norm'. 'Normative' claims say what ought to be, not what is.
Reciprocity is a strong social norm in every society studied.
Returning a favour is a rule people are expected to follow in every society examined.
- 38overlapverbneutral
to cover part of the same area or subject as something else, or the shared part itself
Stress tells the two uses apart: the verb is stressed on the last syllable and the noun on the first. The verb takes 'with' and the noun takes 'between', which is worth drilling because literature reviews need both: this study overlaps with earlier work, there is little overlap between the two samples. The p doubles in overlapped and overlapping.
The two questionnaires overlap in about a third of their items.
Roughly one question in three appears on both forms.
- 39passiveadjectiveneutraltechnical
accepting what happens without acting, or, in grammar, having the subject receive the action
Two senses, and students meet both. In grammar the passive voice puts the receiver of the action first, which is why method sections use it to keep attention on the procedure rather than the researcher. Outside grammar it means accepting rather than acting, giving passive smoking, passive resistance and a passive role. Noun 'passivity', opposite 'active'.
Method sections often use the passive so the focus stays on the procedure.
Writers describe a method with the verb form that hides who acted, keeping attention on the steps.
- 40portionnounneutral
a part or share of a larger whole
A piece of a whole, and more formal than 'part'. The trap is 'proportion', which is a ratio rather than a piece: 'a large portion of the budget' is a chunk of money, while 'the proportion of women in the sample' is a percentage. If a figure with a percent sign follows, you almost certainly want proportion. The food sense gives 'portion size'.
A sizeable portion of the budget goes on transport.
A large slice of the money is spent on moving people about.
- 41preliminaryadjectiveformal
coming before the main part of something, and therefore provisional
It marks results as provisional, so 'preliminary findings' promises the reader that the conclusions may change once the rest of the data arrives. Use it honestly rather than as modesty. Note the division of labour with 'pilot': a pilot study is the study itself, while preliminary describes what has come out of one so far. The plural noun 'preliminaries' means the preparatory stages.
These are preliminary findings from the first sixty interviews.
These early results come from the first sixty interviews and may change.
- 42protocolnounformaltechnical
an official written plan or set of rules governing how something is done
Three worlds, one word. In research it is the written plan an ethics committee approves and the study must follow, which is why 'protocol deviation' is a reportable event. In computing it is the agreed rules for exchanging data. In diplomacy it is correct formal behaviour, and it also names treaties such as the Kyoto Protocol. The usual phrase is 'according to protocol'.
The trial followed a published protocol registered in advance.
The trial kept to a written plan that had been registered before it began.
- 43qualitativeadjectiveformaltechnical
concerned with the nature or qualities of something rather than with amounts that can be measured
Learn it as one half of a pair, qualitative against quantitative, even though only qualitative is an AWL headword. Qualitative work asks what and why using words: interviews, focus groups, observation, analysed into themes. Quantitative work counts and measures, producing numbers and statistics. The hook is quality described against quantity counted, and mixed methods use both. It never means 'high quality', so 'a qualitative school' is wrong.
The team used a qualitative design based on thirty interviews.
The team gathered words rather than numbers, working from thirty conversations.
- 44refineverbneutral
to improve something by making small changes to it
Improvement by small adjustments rather than by replacement, which is exactly what happens to a model, a definition, a coding scheme or an estimate as work proceeds. The industrial sense gives refined oil and refined sugar. Watch the adjective, because 'refined' applied to a person means polished or cultivated. The countable noun is 'refinement': two refinements to the model.
The coding scheme was refined after the first ten transcripts.
Small improvements were made to the labelling system once ten interviews had been typed up.
- 45relaxverbneutral
to make a rule, assumption or restriction less strict, or to become less tense
The sense that surprises learners is the technical one, and it is everywhere in economics and statistics: to relax an assumption, a rule, a constraint or a restriction is to make it less strict. 'If we relax the assumption of normality' does not mean the assumption takes a rest. The everyday sense of resting belongs to speech. The noun 'relaxation' serves both.
The model still holds if we relax the assumption of equal variance.
Loosening the requirement that spread be the same leaves the model working.
- 46restrainverbformal
to hold something or someone back, or to keep something under control
Hold back, by force or by self-control. It sits in a trio: you restrain something that would otherwise act, restrict the amount or scope of something, and are constrained by circumstances you cannot change. The noun 'restraint' covers both self-control and an imposed limit, and the adjective 'restrained' means measured or understated, which is praise in academic prose.
Higher interest rates are meant to restrain borrowing.
Raising the cost of loans is supposed to hold down how much people borrow.
- 47revolutionnounneutral
a complete change in a system or society, or one complete turn around a centre
One spelling, two unrelated-looking senses that share a root meaning of turning: the overthrow of a political order, and one complete turn, as in revolutions per minute. The first has spread into 'the digital revolution' and 'the green revolution' for any sweeping change. Distinguish 'revolt', which is the uprising itself, from the lasting change a revolution names. 'Revolutionary' works for both senses.
The Industrial Revolution reshaped where people lived and worked.
The great upheaval in industry altered where people made their homes and earned a living.
- 48rigidadjectiveneutral
stiff and unable to bend, or unwilling to change or be adapted
Physically stiff, or unwilling to bend on a rule. Applied to people, systems or thinking it is almost always a criticism, so it is not a neutral synonym for 'strict' or 'consistent'. The costly confusion is with 'rigorous', which is praise and means careful and thorough: a rigorous method is a good one, a rigid method is a fault. Nouns 'rigidity' and 'rigour'.
The timetable is too rigid for part-time students.
The schedule cannot bend enough to suit those studying alongside a job.
- 49routenounneutral
a way taken to get from one place to another, or a course towards a goal
A homophone problem. In British English it sounds exactly like 'root', while many American speakers rhyme it with 'out', and the spelling error runs in both directions: it is 'root cause' and 'grass roots', but 'en route' and 'a route into teaching'. The figurative use is common in education writing, where an apprenticeship is a route into a profession. The verb means to send by a particular path.
Apprenticeships offer another route into the profession.
Training on the job is a second way of entering the occupation.
- 50scenarionounneutral
an imagined or predicted sequence of events, used to think through what might happen
An imagined chain of events used to reason about consequences, which is why climate and economic modelling speak of emissions scenarios and scenario planning, and why 'worst-case scenario' is fixed. The plural is 'scenarios'. Do not use it to mean 'situation' or 'case', because a scenario is hypothetical and calling a real event a scenario says the opposite of what you mean.
The report models three warming scenarios to 2100.
The report works through three imagined futures for heating up to 2100.
- 51spherenounformal
a round three-dimensional shape, or an area of activity, interest or influence
The geometric ball is the literal sense, but academic writing mostly uses the figurative one: an area of activity or influence. Hence the public sphere, the private sphere, the political sphere and a sphere of influence. 'The public sphere' is a term of art in social theory for the space where citizens debate. The adjective 'spherical' belongs only to the shape.
Religion withdrew from the public sphere but not from private life.
Faith left the arena of shared civic debate while remaining in people's homes.
- 52subordinateadjectiveformal
lower in rank or importance, or a person in a lower position
Adjective, noun and verb, and the verb is the one that sounds different: its final syllable is fully pronounced where the adjective and the noun swallow it. The stress itself does not move. Grammar uses it constantly: a subordinate clause cannot stand alone and hangs off a main clause, usually behind 'because', 'although' or 'which'. In an organisation a subordinate is someone lower in rank. As a verb, 'subordinate X to Y' means treat X as the less important of the two.
The second half of the sentence is a subordinate clause.
The latter part of the sentence cannot stand alone and depends on the main one.
- 53supplementnounneutralformal
something added to improve or complete another thing, or to add something in that way
Noun and verb are both stressed on the first syllable, and what separates them is the last one, swallowed in the noun and fully sounded in the verb. The verb takes 'with' and means add to what is already there rather than replace it: supplement an income with evening work. The adjective every researcher needs is 'supplementary', because journals put extra tables and data in the supplementary material; American English also uses 'supplemental'.
Many students supplement their loans with part-time work.
Many students add earnings from a job to the money they borrow.
- 54suspendverbformal
to stop something for a period of time, or to hold something floating in liquid or air
Two senses, both frequent in academic and news prose. To stop temporarily: suspend trading, suspend a pupil, a suspended sentence, which is one not served unless the offender reoffends. And to hold in place within a liquid or in the air, which gives particles suspended in water. The noun 'suspension' carries both, plus a chemical sense. 'Suspense' is a different idea entirely.
Trading was suspended for two hours after the announcement.
Buying and selling stopped for two hours once the news broke.
- 55teamnounneutral
a group of people working together on the same task
A collective noun, and British English will treat it as plural when the members are what matter, so 'the team have disagreed' is correct there while American English keeps the singular throughout. In papers 'the research team' is the standard way of saying 'we' without saying it. 'Teamwork' is one word; the phrasal verb 'team up with' is too informal for a thesis.
The research team met weekly to compare their coding.
The group of researchers gathered every week to compare how they had labelled the data.
- 56temporaryadjectiveneutral
lasting for only a limited period rather than permanently
Lasting for a limited time, the opposite of permanent. Its lookalike is 'temporal', which means relating to time in general (temporal trends, the temporal lobe) or worldly rather than spiritual, and swapping the two changes the meaning completely. Collocations: a temporary contract, temporary accommodation, a temporary measure. The adverb 'temporarily' is regularly misspelled.
The scheme was introduced as a temporary measure in 2020.
The plan was brought in for a short period only in 2020.
- 57triggerverbneutral
to cause something to begin suddenly, or the event or thing that causes it
To set something off suddenly, and usually something unwelcome: trigger a recession, a reaction, a debate, an alarm. It implies immediacy, so it does not suit a slow build-up. The noun names the cause as well as the part of a gun, and psychology now uses it for anything that provokes distress. The g doubles in triggered and triggering.
The announcement triggered a sharp fall in the currency.
The exchange rate dropped steeply as soon as the news came out.
- 58unifyverbformal
to join separate parts or groups into a single whole
To make separate parts into one whole, used of countries, systems and theories, and the noun 'unification' is the form history books use. Compare 'unite', which is more about people joining in common action, and 'united', which survives in names. Spelling follows the -fy rule, so the y becomes ie before an ending: unifies, unified, but unifying keeps it.
No single theory has managed to unify the two sets of findings.

to break a rule, law, agreement or right
The formal verb for breaking something that was meant to hold: a law, a right, an agreement, a rule, an assumption. Statistics uses it neutrally and often, as in 'the residuals violate the assumption of constant variance'. Elsewhere it carries a heavy moral charge and one sense refers to sexual assault, so keep it for rules and standards. Noun 'violation'.
The residuals violate the assumption of constant variance.
The leftover errors break the requirement that spread stay the same throughout.

the ability to see, or an imagined idea of how the future should be
Three senses share the word: eyesight, as in impaired sight; a picture of how the future should be, as in a strategy document; and something seen in a dream. Policy and business writing lean on the second so heavily that it often carries no content, and a concrete aim is nearly always better. 'Visionary' praises a person, 'visual' relates to seeing, and only the first sense is medical.
Poor vision went undetected in a quarter of the children.
A quarter of the children had trouble seeing and nobody noticed.
