The logic, argument, and formal-reasoning terms every LSAT question is built on — plus the advanced vocabulary that fills Reading Comprehension passages. Flip, self-grade, and drill only what you haven’t mastered. Free, no signup.
How to use: start with the Formal Logic and Logical Reasoning categories — those terms unlock the question stems. Tap a card to flip, grade yourself, and switch on “Hide words I know” to focus on what’s left.
A statement offered as evidence or support for a conclusion in an argument.
“Identify each premise before deciding whether the conclusion actually follows from them.”
The LSAT isn’t a vocabulary test in the GRE sense — but it does assume fluency in two very different word banks. The first is the language of logic and argument: terms like sufficient condition, necessary assumption, contrapositive, and flaw are the literal grammar of every Logical Reasoning stem. If you have to stop and decode what a question is asking, you’ve already lost time you can’t spare.
The second is the advanced reading vocabulary that fills the test’s dense Reading Comprehension passages — words like tenuous, ostensible, corroborate, and spurious. You won’t be asked to define them, but tripping over them mid-passage breaks your comprehension exactly when you need it most.
Logical Reasoning makes up the largest scored portion of the LSAT, and it’s the section where terminology pays off fastest. When “necessary assumption” instantly means the answer the argument would collapse without, you stop parsing the prompt and start solving it. Use the category filter to drill Formal Logic and Logical Reasoning until those terms are automatic, then move on to the passage-vocabulary cards to build reading speed.
Pair this with the concepts in depth: our conditional statements guide, the logical reasoning question types, and reading comprehension strategies.
Does the LSAT test vocabulary?
Not the way the GRE does — there is no Sentence Equivalence section. But the LSAT does assume you know its working vocabulary: the logic and argument terms every question stem is built on (assumption, necessary vs. sufficient, flaw, principle) and the advanced words that appear throughout Reading Comprehension passages. Knowing these terms cold lets you decode question stems instantly and read dense passages without stumbling.
What terms do I most need to know for the LSAT?
The highest-value set is the formal-logic and argument vocabulary: sufficient condition, necessary condition, contrapositive, assumption, premise, conclusion, strengthen, weaken, flaw, and inference. These words define what each question is actually asking. On top of that, a bank of advanced reading vocabulary — words like tenuous, ostensible, corroborate, and spurious — keeps dense passages from slowing you down.
Are these LSAT flashcards free?
Yes, completely free with no signup. Filter by category — Formal Logic, Logical Reasoning, Common Flaws, Reading Comprehension, and Passage Vocabulary — and the tool tracks which terms you have mastered in your own browser.
How should I use LSAT terminology flashcards?
Learn the logic and argument terms first, because they unlock the question stems in Logical Reasoning — the largest scored portion of the test. Once a term like "necessary assumption" is automatic, you spend your time reasoning instead of decoding the prompt. Then drill the passage-vocabulary cards to build reading speed. Short daily sessions work best.
