How Important Are ACT Vocabulary Words? 

Vocabulary questions are one type of question you’ll encounter in the Reading section and the English section of the ACT. Here are the types of ACT vocabulary questions you can expect to see in each section. 

 

ACT Reading Vocabulary 

These questions on the ACT Reading section that require knowledge of vocabulary terms are called “Vocab in Context” (VIC) questions. 

Vocab in Context questions on the Reading section of the ACT test your ability to think analytically and use context clues in order to do two main things:

  • Determine how an author’s use of a word affects the meaning of a larger portion of text, and 
  • Determine the meaning of a word or phrase in a specific situation.

When answering VIC questions, test takers will most often be asked to identify the correct meaning of a vocabulary word or phrase based on its usage in a passage of text provided on the exam, or you’ll have to choose one vocabulary word to sum up the meaning of a passage of text. 

On all Vocab in Context questions, you should pick the word that is most correct given the a) context of the passage and b) the other answer options. This can sometimes be tricky for students, especially since words have multiple meanings. 

Take the word “net” for example. In its most common usage, a “net” is an open-weaved or mesh fabric. If you’ve just read a passage about money, that wouldn’t make much sense! But “net” can also mean “to receive by way of profit.” In that case, “net” might be the most correct answer choice. 

 

ACT English Vocabulary 

The ACT English section also tests vocabulary in context. That means you’ll have to understand what words mean based on how they’re being used in a sentence. 

These questions are different from those on the ACT Reading section because you’re rarely, if ever, asked about one specific word. Instead, you’ll be asked to evaluate whether phrases are grammatically correct and/or make sense based on how they’re being used in a paragraph.

Put another way: the ACT English exam doesn’t specifically test vocabulary by asking you to define a single word. Instead, it tests your vocabulary knowledge by 

Here’s what we mean: take this excerpt from the official ACT practice questions website: 

body-ACT-vocabulary-sample-question

Here’s the question that you’re asked about this passage: 

body-act-vocabulary-sample-answerWhile the question isn’t specifically asking you about the definition of the words “subservient” or “disposal,” you need to know what they mean in order to determine whether that phrase makes sense in the context of the sentence. 

“Subservient” means “useful in an inferior capacity” and “disposal” means “the power or authority to make use of as one chooses.” Once you consider those meanings, the sentence doesn’t make much sense. The correct answer is C, but you wouldn’t know that if you didn’t have a strong knowledge of vocab! 

While background knowledge and inference can be helpful for getting the gist of the meaning of a word, on the ACT the best approach is to make sure you recognize and understand key vocabulary words so you don’t have to rely on context clues or guessing

That’s why studying ACT vocabulary is so important!

3 Methods for Studying ACT Vocabulary

There are a variety of methods for preparing to ace ACT test vocabulary, but some are definitely better than others. Here, we’ll give you the details on a bad, better, and best study method for ACT vocab.

 

Bad: Reading an ACT Test Vocab List

A common method for studying ACT vocab is to read over a list of vocabulary words with their definitions. While reviewing a vocab list will familiarize you with the words that may appear on the ACT, this method doesn’t help you truly learn the vocab words and their definitions. 

Here’s why reading lists of vocab words isn’t a great study method: lists give equal priority to vocab words that are easy and hard for you. It makes sense that you would need to spend more time learning and reviewing those vocab words that you really struggle with, and less time reviewing words that you’ve already perfected, right? 

But reading over a list of words doesn’t push you to learn the words that are the hardest for you. In fact, it makes it easier for you to gloss over the terms that stump you without committing them to memory. That’s why reading through ACT vocabulary lists isn’t the best method for learning ACT vocab.

 

Better: Writing Down Vocabulary Terms 

Another way to study ACT vocabulary is writing down each term and its definitions on notebook paper. To do this, you’ll download a list of vocabulary terms, then write each one down with its corresponding meanings. You can even look up additional definitions and add them to your sheet. This can be helpful because writing information down by hand has been proven to help with memory retention

Unfortunately, this isn’t the best way to study ACT vocab, either. One, it takes a lot of time to do! While that might not be a problem if you’re studying in advance, crammers will find this is too time consuming to be useful. 

Additionally, not all people memorize information the same way! So if writing things down makes you more distracted and less likely to study, then this won’t be a great ACT vocab study method for you. 

 

Best: The Waterfall Method

By far the most effective method for studying for ACT vocab questions is what’s known as the Waterfall Method. In this study method, words that are hard for you “cascade” down into further piles as you review flashcards so that you spend the most study time focusing on the hardest vocab words. 

Here’s how to use the Waterfall Method, step-by-step:

Create a set of 30 to 50 ACT vocab flashcards.

body_vocab1

Begin reviewing the flashcards, one by one. When you review a card that you immediately know, place that card in a “Know It” pile. When you hesitate or struggle to produce the meaning of a vocabulary word, place the flashcard in a “Struggled” pile. This will leave you with two stacks of cards.

body_vocab2

Pick up the “Struggled” pile of cards and repeat the review process. As you review these cards, place the ones you immediately get right into a new Know It pile (you might think of it as “Know It 2”), and the ones you have a hard time with in a Struggled pile. At the end of this round, you’ll have three piles: “Know It”, “Know It 2”, and “Struggled.”

You'll end up with three stacks of cards. 

body_vocab3

Keep repeating the process of reviewing words from your Struggled pile and creating additional Know It piles until you’re left with only one to five cards in your Struggled pile.

body_vocab4

At this point you know most of your list of ACT vocabulary words, but you still need to learn those one to five cards in the remaining Struggled pile that are really difficult for you. To master the words in your final Struggled pile, go back up the “waterfall” reviewing flashcards in reverse. 

First, add your Struggled pile to your last Know It pile; this becomes your “Working” pile.

body_vocab5

Review all the flashcards in your Working pile, and if you forget any of the words in this pile, start over reviewing the Working pile again. 

When you master the cards in the Working pile, combine it with the next Know It pile. Repeat the review process, starting over if you miss a word. Each time you master all of the words in your Working pile, combine it with the next Know It pile until you’re down to one single stack of cards. 

body_vocab6

Finish your studying by reviewing every card in your single Working stack. If you get them all, you’re as close as you’re likely to get to memorizing every single word in your ACT vocab list!

body_vocab1

And that’s how you implement the Waterfall study method, step-by-step. This method has been shown to work because you’ll be working overtime to learn those vocab words that are the most difficult for you, since this method requires you to review your hardest words at least 10 more times than those words that you get right off the bat.
