Digital SAT Reading and Writing questions test how words and transitions function in context, which is why a list of rare words moves the score so little. These 300 independently written cards build precise meaning, evidence language, rhetorical relationships and high-utility transition logic; the final section concentrates on qualification, cross-text synthesis, inference and sentence-to-sentence connection. Each answer supplies a concise meaning, a context cue and an original sentence. Import it and the whole deck joins your spaced-repetition schedule. Words you already know stretch out and drop out of sight; the ones that keep slipping come back until they stop slipping. What goes down is the number of words you still don't know — not the time it takes to flip past 300 cards you mostly do.

What's inside

Showing 100 representative cards from the full 300-card deck.

Front	Back
assertion (noun)	A statement presented as true, often without full proof yet. Cue: look for a writer making a claim that needs support. Example: Her assertion that the policy saved money sounded confident, but the report still needed evidence.
proposition (noun)	A statement or idea proposed for consideration, especially one that can be argued for or against. Cue: often appears as a plan, suggestion, or thesis. Example: The proposition that homework should be shorter sounded reasonable to many students.
thesis (noun)	The main controlling claim of a speech or essay. Cue: it tells you what the writer is trying to prove. Example: The thesis of the article was that city gardens improve neighborhood life.
interpretation (noun)	An explanation of what evidence, words, or events mean. Cue: different readers may have different interpretations of the same passage. Example: His interpretation of the graph was more cautious than hers.
induction (noun)	Reasoning that starts with examples or observations and builds toward a broader conclusion. Cue: one clue is not enough; repeated patterns matter. Example: After several rainy summers, the farmer’s induction was that the region was becoming wetter.
evidence (noun)	Facts, details, or examples used to support a claim. Cue: ask whether the evidence is strong, relevant, and sufficient. Example: The chart provided evidence that attendance rose after the schedule change.
support (noun)	Material that backs up a claim or idea. Cue: support can be facts, quotations, examples, or data. Example: The writer used survey results as support for the proposal.
citation (noun)	A reference to a source used to show where information came from. Cue: citations make evidence traceable and credible. Example: Her citation of the researcher’s article strengthened the essay.
indicator (noun)	A sign or piece of evidence that suggests something is true. Cue: indicators point toward a larger pattern, but they may not prove it alone. Example: Rising bus ridership was an indicator that the new route was useful.
validate (verb)	To confirm that an idea, result, or claim is sound or accurate. Cue: validation often comes from a trusted source or repeated result. Example: The second experiment helped validate the scientist’s hypothesis.
demonstrate (verb)	To clearly show or prove something through evidence, action, or example. Cue: a strong example can demonstrate an abstract idea. Example: The experiment demonstrated that the plant grew faster with more light.
attest (verb)	To confirm or give evidence that something is true. Cue: often used when a person or record supports a fact. Example: Several photographs attest to the condition of the old bridge.
sustain (verb)	To maintain or support a claim with evidence over time. Cue: in arguments, support must sustain the point, not just mention it once. Example: The data sustained the author’s belief that the program was effective.
supportive (adjective)	Giving help, proof, or encouragement. Cue: a supportive detail backs up the argument rather than distracting from it. Example: The graph was supportive of the writer’s explanation.
reliable (adjective)	Dependable and likely to be accurate or consistent. Cue: reliable evidence is something you can trust again and again. Example: The long-term study was more reliable than a quick opinion poll.
compelling (adjective)	Very persuasive because it is clear, powerful, or interesting. Cue: a compelling claim pulls the reader in and feels hard to ignore. Example: The article made a compelling case for restoring the park.
charge (noun)	An accusation that someone has done something bad or illegal. Cue: in an argument, a charge may need proof. Example: The charge that the company misled customers was taken seriously.
speculation (noun)	A guess or theory based on limited information. Cue: speculation is weaker than evidence-based conclusion. Example: The rumor was only speculation, not something the facts could prove.
hypothesis (noun)	A tentative explanation that can be tested with evidence. Cue: in science and analysis, a hypothesis is an informed starting point. Example: Her hypothesis was that the seeds would sprout faster in warmer soil.
logic (noun)	Clear, orderly reasoning that connects evidence to a conclusion. Cue: logic helps you see whether a claim actually follows. Example: The logic of her argument was easy to follow because each step built on the last.
analysis (noun)	Careful study of parts of something to understand how it works or what it means. Cue: analysis often goes beyond summary by explaining relationships. Example: The analysis of the chart showed a clear rise after lunch.
clarification (noun)	Extra detail that makes a statement easier to understand or less ambiguous. Cue: clarification often removes confusion about an argument. Example: The teacher’s clarification of the instructions helped everyone finish faster.
explicit (adjective)	Stated clearly and directly, with little chance for confusion. Cue: explicit evidence or language leaves fewer gaps to infer. Example: The directions were explicit about when to turn in the project.
inconclusive (adjective)	Not strong enough to prove one answer or one final conclusion. Cue: inconclusive evidence leaves the issue open. Example: The first test was inconclusive, so the team ran another trial.
tenable (adjective)	Able to be defended with reason or evidence. Cue: if a position is no longer tenable, it cannot hold up well under scrutiny. Example: After the new data appeared, the old explanation was no longer tenable.
correlative (adjective)	Showing a relationship where two things change together, though one may not directly cause the other. Cue: correlation is not the same as causation. Example: The correlative rise in heat and ice cream sales did not prove one caused the other.
correlation (noun)	A connection or pattern in which two things vary together. Cue: correlation suggests a relationship, not necessarily cause. Example: The correlation between study time and scores was clear, but the reason still needed analysis.
cause (noun)	The reason something happens. Cue: ask what triggered the event or change. Example: The cause of the power outage was a damaged wire.
prompt (verb)	To cause or encourage something to happen. Cue: a prompt can be a signal, event, or detail that leads to a response. Example: The discovery prompted the researcher to revise her claim.
stem (verb)	To arise from or be caused by something else. Cue: if a problem stems from a cause, that cause is the source. Example: The confusion stemmed from unclear directions.
responsible (adjective)	Being the likely cause of something or accountable for it. Cue: in analysis, “responsible for” often points to cause. Example: The broken thermostat was responsible for the cold classroom.
related (adjective)	Connected by topic, cause, family, or pattern. Cue: related ideas may belong in the same argument or paragraph. Example: The professor grouped related observations into one chart.
equivalent (adjective)	Equal in value, meaning, or effect. Cue: equivalent choices or claims match closely enough for comparison. Example: For this assignment, two short sources were equivalent in usefulness.
difference (noun)	A way in which things are not the same. Cue: differences often matter more than surface resemblance when analyzing texts. Example: The main difference between the plans was the cost.
comparison (noun)	The act of examining two or more things to see how they are alike or different. Cue: comparison can help reveal patterns or priorities. Example: The comparison of the two proposals made the better one obvious.
equate (verb)	To treat two things as equal or the same. Cue: be careful not to equate correlation with causation. Example: The speaker warned students not to equate speed with quality.
resemble (verb)	To look like or be similar to something else. Cue: resemblance supports comparison, but it does not prove identity. Example: The new logo resembled the old one, though the colors were different.
divergent (adjective)	Moving apart or becoming different in view, direction, or result. Cue: divergent ideas often signal disagreement or contrast. Example: The two researchers reached divergent conclusions from similar data.
analogy (noun)	A comparison that explains one thing by relating it to another, usually more familiar thing. Cue: analogies help readers understand relationships. Example: The article used an analogy between a city and a living organism.
coherence (noun)	The quality of being logically connected and easy to follow. Cue: coherent arguments move smoothly from claim to evidence to conclusion. Example: The coherence of the essay made each paragraph feel connected.

Frequently asked

Does importing this deck use AI credits?

No. Importing uses the saved deck as published; it does not run AI generation or use AI credits. The complete deck can therefore be imported on the free plan.

What happens if I import the deck twice?

Existing cards are skipped. A later import only adds genuinely new cards, so it does not create a second copy of the same material. Including re-imports after deletion, the same Memly curated deck can be imported up to three times per account over its lifetime.

Can I change or remove cards after importing?

Yes. Imported cards belong to your account. You can edit either side, delete cards, add notes, or move them to another deck.

Can I study the same deck on web and mobile?

Yes. The deck is added to your Memly account and stays available across the web app and the iOS and Android apps.

Who writes these cards?

Memly writes all of them — every meaning, context cue and example sentence. That is deliberate: the digital SAT tests how a word functions inside a sentence, and a borrowed glossary entry cannot show function.

Why does this deck include rhetorical and logical words?

SAT vocabulary is tested in context. Words that signal claims, evidence, contrast, cause, tone and degree help with both vocabulary-in-context and passage reasoning.
