GAMSAT · Get comfortable with the vocabulary.

thesis statement

A single sentence that states the central claim of an essay, giving the reader a clear position that the rest of the writing supports and develops.

Related: argument, topic sentence
topic sentence

The opening sentence of a paragraph that announces its main idea and shows how that paragraph connects to the essay's overall argument.

Related: thesis statement, cohesion
cohesion

The way sentences and paragraphs are linked so writing flows logically, achieved through connectives, repeated key words, and consistent pronoun reference.

Related: topic sentence, register
register

The level of formality in language chosen to suit an audience and purpose, ranging from conversational to formal academic prose.

Related: cohesion, connotation
connotation

The emotional or cultural associations a word carries beyond its literal meaning, which shape how a reader responds to a phrase.

Related: denotation, register
denotation

The literal, dictionary meaning of a word, considered apart from any emotional associations or implied suggestions it may carry.

Related: connotation
counterargument

An opposing view introduced into an essay and then answered, demonstrating that the writer has considered alternative positions before defending a conclusion.

Related: argument, thesis statement
argument

A reasoned line of thinking in which evidence and explanation are used to support a claim, rather than mere assertion or disagreement.

Related: counterargument, thesis statement
evidence

Information such as examples, data, or reasoning offered to support a claim and persuade a reader that it is credible.

Related: argument, generalisation
generalisation

A broad statement applied to a whole group from limited cases; persuasive writing must qualify such claims rather than overstate them.

Related: evidence, hedging
hedging

Language that softens a claim, such as possibly or tends to, acknowledging uncertainty and limiting how far a conclusion is asserted.

Related: generalisation, argument
rhetorical question

A question asked for persuasive effect rather than to obtain an answer, inviting the reader to accept an implied point.

Related: argument, register
utilitarianism

An ethical theory judging actions by their consequences, holding that the right action produces the greatest overall welfare for all affected.

Related: deontology, social contract
deontology

An ethical approach holding that certain duties and rules are binding regardless of outcomes, so some acts are wrong even if they produce good results.

Related: utilitarianism, autonomy
autonomy

The capacity of a person to make informed decisions about their own life, a principle central to consent and medical ethics.

Related: deontology, informed consent
social contract

The idea that political authority rests on an implicit agreement among citizens to accept shared rules in exchange for protection and order.

Related: utilitarianism, distributive justice
distributive justice

The question of how benefits and burdens in a society should be shared fairly among its members, including access to healthcare and education.

Related: social contract, equity
equity

Fairness in treatment that accounts for differing needs and circumstances, distinguished from treating everyone in exactly the same way.

Related: distributive justice, autonomy
informed consent

Agreement to a procedure or study given by someone who understands its purpose, risks, and alternatives, and who decides freely.

Related: autonomy, confidentiality
confidentiality

The obligation to keep personal information private and to disclose it only with permission or where a clear justification exists.

Related: informed consent, autonomy
correlation

A statistical relationship in which two variables vary together, which does not by itself establish that one causes the other.

Related: confounding variable, statistical significance
confounding variable

An unmeasured factor linked to both the supposed cause and the observed outcome, which can create a misleading apparent relationship.

Related: correlation, control group
control group

The comparison group in an experiment that does not receive the treatment, allowing researchers to isolate the effect being tested.

Related: confounding variable, randomisation
randomisation

Assigning participants to groups by chance so that known and unknown differences are spread evenly and bias is reduced.

Related: control group, confounding variable
statistical significance

A result unlikely to have arisen by chance alone under a stated probability threshold, indicating a real effect is plausible.

Related: correlation, sample size
sample size

The number of observations in a study; larger samples generally give more precise estimates and greater power to detect effects.

Related: statistical significance, randomisation
homeostasis

The maintenance of stable internal conditions, such as temperature and blood glucose, through feedback mechanisms that resist change.

Related: negative feedback, osmosis
negative feedback

A control mechanism in which a change triggers a response that reverses the change, restoring a variable toward its set point.

Related: homeostasis, enzyme
osmosis

The movement of water across a partially permeable membrane from a region of higher water concentration to one of lower water concentration.

Related: homeostasis, diffusion
diffusion

The net movement of particles from an area of higher concentration to lower concentration, driven by random molecular motion.

Related: osmosis, concentration gradient
concentration gradient

A difference in the concentration of a substance between two regions, which provides the driving force for diffusion and transport.

Related: diffusion, osmosis
enzyme

A protein that speeds up a biochemical reaction by lowering its activation energy, acting on a specific substrate at its active site.

Related: negative feedback, activation energy
activation energy

The minimum energy required for a reaction to proceed, which enzymes reduce so reactions occur at body temperature.

Related: enzyme
allele

One of the alternative versions of a gene at a given position on a chromosome, which may produce different observable traits.

Related: genotype, phenotype
genotype

The particular combination of alleles an organism carries for a gene or set of genes, which interacts with environment to shape traits.

Related: allele, phenotype
phenotype

The observable characteristics of an organism, resulting from the interaction between its genetic makeup and its environment.

Related: genotype, allele
natural selection

The process by which heritable traits that improve survival and reproduction become more common in a population over generations.

Related: allele, phenotype
pH

A logarithmic scale measuring hydrogen ion concentration, where values below seven are acidic and above seven are alkaline.

Related: enzyme, concentration gradient
mole

The amount of substance containing a fixed number of particles, used to convert between mass and numbers of reacting particles.

Related: concentration gradient
