The 327 TOEFL words you need to know

THE 327 TOEFL WORDS YOU NEED TO KNOW

Below are the 327 best TOEFL vocabulary words, in alphabetical order.

HOW TO USE THIS TOEFL VOCABULARY LIST

First, you should read through the list and identify any words you don’t know or are unsure of. If you’re even slightly unsure of a TOEFL vocabulary word, you’ll want to study it. Be sure to read the definition and sample sentence of words you feel confident on to be sure you understand them fully.

THE BEST WAY TO USE YOUR TOEFL FLASHCARDS

We recommend using the waterfall method to learn TOEFL words. If you’re not sure what the waterfall method is, we break it down for you below.

Once you have your TOEFL vocabulary flashcards, you’ll go through those cards one by one. For each card whose definition you know easily, you’ll put it in a “Know It” pile. If you don’t know the definition of a particular TOEFL word, put it in a “Struggled” pile.

After you’ve gone through each of the cards once, pick up your “Struggled” pile. You’ll now go through this pile again. For words where you know the definition, place them in a second “Know It” pile next to (but not combined with) the first “Know It” pile. For words you don’t know, make a new “Struggled” pile. Repeat this process, placing new “Know It” piles in a row from left to right. This creates your waterfall. Repeat this process until the “Struggled” pile has only a few words left.

Now, you’ll move back up the waterfall. Starting with the most recent “Struggled” pile, go through the flashcards until you know all the words in the pile. Then, add the most recent (the rightmost) “Know It” pile. Go through those words. If you miss any, go through the entire pile again until you get all of them right. It may take awhile to get through the entire pile, but this method will guarantee that you learn those TOEFL words! Continue this process until you get all the way back up the waterfall.

This is the best method to study vocab flashcards because you’ll spend the majority of your time reviewing the words you struggle the most with, as opposed to just studying the entire stack over and over.
