MCAT Vocabulary List

June 25, 2024

minute read

The MCAT places a significant emphasis on your knowledge of English vocabulary. MCAT especially demands a large amount of reading and comprehension. 

Aceing the MCAT depends on your ability to understand general scientific terminology and fundamental graduate-level vocabularies. 

Needless to say, having a wide range of vocabulary is crucial as you prepare and study for the MCAT

This article focuses on an MCAT vocabulary list that will certainly be beneficial during your MCAT preparation. Let’s get started.

Is Vocabulary Important for the MCAT?

There is no ‘vocabulary’ test on the MCAT. 

However, there are passages with concepts, and the vocabulary is in the context of passages or essays. Therefore, the MCAT, like any other test, requires you to have a strong grasp of vocabulary. 

Comprehending the passages and the questions on the MCAT will be difficult if your vocabulary skills are weak. This could greatly affect your MCAT score

Furthermore, you will not be able to impress the admission committee if you use average and common vocabulary in your personal essays and statements.

Hence, having an excellent vocabulary is key to succeeding in every aspect of the MCAT.

When Does Vocabulary Show Up on the MCAT?

The MCAT, being an English test, is, at the same time, a vocabulary test. 

Vocabulary is crucial in all four sections of the MCAT:

You will only be able to answer the questions correctly if you understand the questions and the options with which you are given. 

It is quite noting, however, that your vocabulary skills will be primarily tested in the MCAT's Critical Analysis and Reasoning Skills (CARS) section.

An excerpt from the AAMC about the CARS part is provided below:

“The passages on the MCAT CARS are typically 500 to 600 words long, but they are complex, frequently thought-provoking works of literature with strong vocabulary and, occasionally, intricate writing styles.”

Do not be intimidated by the word "complex.” 

Even if you do not understand a word at first, you may always determine its meaning by using context clues.

Is There an Official Vocabulary List I Should Be Studying for the MCAT?

There isn't an official MCAT vocabulary list to learn from, but you should make it a habit to read every day. This also applies to reading books or articles you find interesting. 

For example, you are free to read a short novel about a kid wizard or an autobiography of a basketball coach.

Instead of just memorizing a dictionary definition, you will come across unfamiliar terms and see them utilized in sentences. 

Try to infer the word’s meaning from the author's tone and the other words in the phrase before you look it up. This will help you become a strong, active reader and help you focus on the minute elements that the MCAT will ask you to identify!

How helpful it is to learn Greek and Latin roots, prefixes, and suffixes, especially in the sciences, cannot be overstated. 

Consider phrases like "hepatitis" or "intravenous." If you are familiar with your roots, you can understand the meaning of these phrases without ever having seen them. 

Hepatitis,” for instance, is an inflammation of the liver; “hepato” means liver, and “itis” means inflammation. 

An intravenous injection is one that goes into your veins because “intra” means inside and “venous” means vein. 

Study the Latin prefixes, Latin suffixes, Greek prefixes, Greek suffixes, and Greek base words on the following list.

How to Improve Your Vocabulary for the MCAT

Increasing your vocabulary before the MCAT can occasionally be challenging. 

Some applicants choose to forego this important element entirely in favor of the science portions after seeing a massive pile of vocabulary to learn, which is not the way to go. 

Thankfully, there are ways on how you can improve your MCAT vocabulary. Here are some of them. 

  • Read medical handbooks, magazines, and books. This is an effective way to familiarize yourself with medical terms than by reading such materials. 
  • Listen to podcasts that focus on health and medicine. This method is just as good as reading books and magazines as you get to encounter words that may not be unfamiliar to you. 
  • Look for the meaning of the words to which you have no clue what they may mean. Reading magazines and listening to podcasts will be useless if you do not utilize a dictionary. 
  • Aside from reading articles that focus on health and medicine, make it a point that you read anything that will enhance your comprehension skills. This may differ depending on topics that interest you. 
  • Use mnemonic devices. Remember that when creating mnemonics, unique and memorable words must be used to create a mixture that sticks in your memory. 
  • Keep a journal where you could write terms and their definitions. This way, it will be easier for you to remember these words.
  • Make use of MCAT flashcards. Flashcards are also one of the most effective techniques when it comes to memory retention of MCAT vocabulary.
  • Classify and categorize the terms. The Law of Similarity says that elements or things that share particular characteristics are more likely to be recognized as belonging to the same group, which is much simpler to recall.
