UWorld’s SAT vocabulary list includes 100 common academic words that students may encounter in SAT Reading and Writing passages, college coursework, and beyond. Use these SAT vocabulary words and definitions to expand your vocabulary, improve reading comprehension, and strengthen your preparation for test day.

Understanding Vocabulary in the SAT Reading and Writing Section

The SAT Reading and Writing short passages are chosen to evaluate student comprehension and analytical skills. We've organized these SAT vocabulary tips into categories that reflect the different ways vocabulary appears throughout the Reading and Writing section. Understanding these categories can help you recognize unfamiliar words and determine their meaning in context.

Common SAT vocabulary

Most SAT reading and writing passages include a typical selection of vocabulary words you'll frequently encounter regardless of their subject areas. These words are flexible, as they can function in various contexts, conveying distinct meanings in each. Words like "delegate," "foil," "spike," "stream," and "bank" are a few examples of common SAT vocabulary that you should expect to see throughout the SAT's reading and writing passages.

Subject-specific vocabulary

The SAT Reading and Writing section includes passages from various subject areas and materials, such as academic journals, historical documents, or literary works. These passages incorporate academic and discipline-specific vocabulary to their respective disciplines. Let's look at a couple of examples below:

Passage:

Although leprosy typically develops after a 5-year incubation period, it can take as long as 20 years to show symptoms. The disease's impact is also progressive, meaning the symptoms get worse over time. Although curable, if left untreated, its later stages can be marked by large skin ulcerations, paralysis of the hands and feet, and facial disfigurement.

The passage above was selected from a medical case study on Leprosy. As you can see, words like "incubation" and "ulcerations" belong to the subject area from which the passage was chosen. To get familiar with advanced and specialized vocabulary, you should read texts from various subject areas and sources where these words are commonly used.

Context clues

The SAT emphasizes understanding words in context, discerning meaning from the passage, and being able to use context clues. Context clues are an efficient way to decipher the meanings of unfamiliar words. As you read each of the passages on the SAT, you must analyze their tone, structure, discipline, and writing style to determine the meaning of any tricky words.

You may also see passages with footnotes or annotations that provide further context. Use these context clues to understand the overall purpose of the passage and the sentences within it. Once you've done that, the only thing left is to note any words you're struggling with and guess their meaning. Let's try with one example below:

Passage:

Brain research suggests that new memories go through a period where the memory is likely to change (a labile state) before becoming a lasting (consolidated) memory. Scientists previously believed that—once consolidated—a memory became resistant to change, but recent findings have strongly established that a consolidated memory can re-enter a labile state through a process called memory reactivation, a deliberate recalling of a long-term memory.

Many students can find the word "labile" difficult to understand. But, as you can analyze from the passage above, "a labile state" has been used as an antonym for "consolidated" memory. If you already know the meaning of "consolidate" (something solid and whole), you can guess that it is the opposite of something that is not "solid." In the context of brain and memory, this word can refer to something dynamic and unstable. Therefore, even if you do not know the exact dictionary meaning of "labile," you can still guess it.

Prefixes, Suffixes, and Roots

Using word parts like prefixes and suffixes can provide clues about the meaning of a word, even if you have never encountered it before. Here's how:

  • Prefixes:

Prefixes always occur before the root of a word. For example, in the word "uncommon," "un" is a prefix. Some common prefixes are:

  1. "un-" (not)
  2. "re-" (again)
  3. "pre-" (before)
  4. "dis-" (not, opposite of)
  5. "Con-" (with)"post-" (after)

A thorough knowledge of standard English prefixes can help you understand unfamiliar words easily! For example, if you come across the term "conjoin" and are unsure of its meaning, remove the root word "join." Now, if you use your knowledge of the prefix "con-," which means "with," you will understand that the word "conjoin" means "to join with," which further points to describing a thing or things that are joined together.

  • Suffixes:

As opposed to prefixes, suffixes come after the root word. For example, "recital" uses the suffix "-al'' after the root word "recite." There are a few common suffixes used in standard English grammar, among others:

  1. "-acy" (state or quality)
  2. "-al" (act or process)
  3. "-dom" (place or state of being)
  4. "-ism" (belief system)
  5. "-ity" (quality of something)
  6. "-ment" (condition of something)

So, next time you encounter words like delicacy (delicate + acy), judgment (judge + ment), or endorsement (endorse + ment), be sure to memorize the list of suffixes and their meanings. Doing so will help you decipher the meaning of many tricky words.

  • Roots:

Roots are the core building blocks that make up words and often carry each word's primary meaning. Some common roots include:

  1. "Ambi" (both)
  2. "Aqua" (water)
  3. "Bio-" (life)
  4. "Multi" (many)
  5. "Port-" (carry)
  6. "Form" (shape)

You may encounter words like "conform," "aquatic," "multifarious," and "portable," which consist of root words. Use what you know to navigate the core meaning of any unfamiliar word, along with context clues to crack open the meaning of any tricky word you may encounter on your SAT test.
