LSAT Logical Reasoning Vocabulary Words

You probably know the meanings of most words in the Logical Reasoning section.

However, if you know what all the words mean, the arguments will be much easier to understand.

I've compiled a list of common, but difficult, vocabulary words just from glancing through 4-5 sections of Logical Reasoning (and throwing in some words that you absolutely must know), so this list is obviously not intended to be comprehensive.

Because the LSAT is not intended to be a vocabulary test, you probably know most of the below words already.

However, take a quick glance through this list and make sure you know them all.

Don't spend a great deal of time focusing on vocabulary in your preparation. However, when you see a word you don't understand, look it up. Just as the same concepts and types of arguments appear on multiple exams, the same words and phrases also appear on multiple exams.

Keep in mind that the LSAT sometimes uses one of a word's less-common meanings

For example:

The LSAT often uses the word "phenomenon" to mean "event" rather than "something unusual."

The LSAT often uses the word "advance" to mean "to promote an argument" rather than "to literally move something forward."

  1. This is really helpful!!! I have a weak vocabulary. One of the things throwing me off on the test was not knowing what certain words meant in the stimulus, question stem, and answer choices.

  5. "Adduce" seemed to make an occasional appearance on older LSATs.

    Hello all:

    A word that I've seen on the LSAT a lot is "aesthetic". Reading Comp passages love this word.

    Kindest,

  7. I do find that, sometimes, it is hard for me to get the correct answer on Logical Reasoning because I am not 100% certain on certain words. "Comprehensive," (which you used in your blog:P) "preclude," "diminution," were a few words that I had to actually look up!

    Thank you for the list of vocab words found in logical reasoning and the link to the definitions!
