Academic vocabulary is one of the most important parts of TOEFL iBT preparation. You do not need to know every difficult English word, but you should be comfortable with the words that frequently appear in academic texts, lectures, and questions.
In the previous article, we introduced 50 essential academic words. In this article, you will learn 100 more common academic words with simple definitions, synonyms, and example sentences.
Learning these words will help you:
- Understand TOEFL Reading passages more easily
- Follow academic Listening lectures
- Give clearer Speaking responses
- Write more precise and natural essays
- Understand questions faster
- Guess unfamiliar words from context
Why Is Academic Vocabulary Important?
TOEFL is an academic English test. This means you will encounter vocabulary related to:
- Science
- History
- Education
- Psychology
- Biology
- Business
- Economics
- Environment
- Technology
- Sociology
You do not need to memorize dictionary definitions word-for-word.
Instead, focus on three things:
1. Meaning — What does the word mean?
2. Context — How is the word used?
3. Usage — What words commonly appear with it?
For example:
The researchers observed a significant change in the behavior of the animals.
If you know that observe means “watch carefully,” the sentence becomes much easier to understand.

How to Memorize 100 Academic Words
Trying to memorize all 100 words in one day is not an effective strategy.
Instead, divide them into smaller groups.
Method 1: Learn 10 Words a Day
Study 10 words each day.
For each word:
- Read the meaning.
- Read the example sentence.
- Say the word aloud.
- Write your own sentence.
- Review it later.
For example:
Day 1
- Acquire
- Alter
- Anticipate
- Apparent
- Approximate
- Capacity
- Category
- Cease
- Clarify
- Coherent
Day 2
- Compensate
- Compile
- Comprehensive
- Comprise
- Confirm
- Conflict
- Correspond
- Criteria
- Crucial
- Derive
Continue until you complete all 100 words.
Method 2: Learn Words in Families
Learning related words together can make vocabulary easier to remember.
Example:
Analyze
- analysis
- analytical
- analyze
- analyst
Example:
Modify
- modify
- modification
- modified
Example:
Regulate
- regulate
- regulation
- regulatory
Example:
Interpret
- interpret
- interpretation
- interpreter
When you recognize one word, you may be able to understand related forms in TOEFL Reading or Listening.
Method 3: Learn Opposites
Some academic words are easier to remember in pairs.
| Word | Opposite |
|---|---|
| Increase | Decrease |
| Include | Exclude |
| Explicit | Implicit |
| Initial | Subsequent |
| Diverse | Uniform |
| Flexible | Rigid |
| Accept | Reject |
| Expand | Contract |
| Strengthen | Diminish |
| Simultaneous | Sequential |
Learning pairs can help you recognize relationships quickly in Reading passages.
Method 4: Learn Words in Context
Do not memorize:
Fluctuate = change
Instead, learn:
Prices fluctuate because supply and demand change.
Then create another sentence:
Temperatures fluctuate throughout the year.
This teaches you how the word actually works in English.
TOEFL Vocabulary Strategy: Don't Translate Everything
One common mistake is trying to translate every academic word into your native language.
For example:
The researchers observed a substantial decline in the population.
You do not need to translate every word.
If you understand:
- researchers = scientists
- observed = saw/studied
- substantial = large
- decline = decrease
- population = number of organisms/people
you understand the main meaning.
Your goal is understanding, not perfect translation.
Use Context to Guess Unknown Words
You will encounter words you do not know on the TOEFL.
Do not panic.
Look at the surrounding sentence.
For example:
The population began to diminish, falling from 50,000 to only 20,000.
Even if you do not know “diminish,” the phrase “falling from 50,000 to only 20,000” gives you a strong clue.
Therefore:
diminish = decrease
Context is one of your most powerful TOEFL vocabulary tools.
Common Vocabulary Mistakes
Mistake 1: Memorizing Only Definitions
Knowing a definition is not enough.
You also need to know how the word is used.
Mistake 2: Learning Too Many Words at Once
Studying 100 words in one sitting may feel productive, but you may forget many of them quickly.
Study smaller groups and review frequently.
Mistake 3: Ignoring Word Forms
For example:
analyze
analysis
analytical
These words are related but have different grammatical functions.
Learn the word family.
Mistake 4: Using Difficult Words Incorrectly
Do not use a complicated word simply because it sounds academic.
Correct usage is more important than difficulty.
For example:
The results were significant.
is better than using a sophisticated word incorrectly.
Mistake 5: Forgetting Review
Vocabulary requires repetition.
A good review schedule is:
Day 1 → Day 2 → Day 4 → Day 7 → Day 14 → Day 30
This gives your brain repeated exposure to the vocabulary.
A 7-Day Vocabulary Study Plan
Day 1
Learn words 1–20.
Day 2
Review 1–20 and learn 21–40.
Day 3
Review 21–40 and learn 41–60.
Day 4
Review 1–60 and learn 61–80.
Day 5
Learn 81–100.
Day 6
Review all 100 words.
Day 7
Take a vocabulary quiz and write sentences using your weakest words.
TOEFL Vocabulary Checklist
Before moving to the next topic, ask yourself:
Can I recognize these words in Reading passages?
Can I understand them from context?
Can I identify common synonyms?
Can I recognize their different word forms?
Can I use at least 20 of them in my own sentences?
Can I recognize them when listening?
Can I distinguish similar words?
Have I reviewed them several times?
If you cannot remember a word, don't simply reread the definition.
Write a new sentence using it.
Frequently Asked Questions
How many vocabulary words do I need for TOEFL?
There is no exact number that guarantees a particular score. A strong TOEFL student should focus on understanding common academic vocabulary and being able to use important words correctly.
Should I memorize vocabulary lists?
Yes, vocabulary lists can be useful, but they should not be your only method. Combine memorization with Reading, Listening, Speaking, and Writing practice.
Should I learn synonyms?
Absolutely. TOEFL frequently tests whether you understand words in context. Knowing synonyms can help you recognize the meaning of unfamiliar wording.
What should I do when I see an unknown word?
First, determine whether the word is important. Then use context clues, word parts, and surrounding sentences to estimate its meaning.
Is it better to learn 100 words quickly or 10 words deeply?
For long-term retention, learning smaller groups and reviewing them repeatedly is generally more useful than trying to memorize a large list once.
Final Thoughts
Academic vocabulary is not about memorizing thousands of difficult words.
It is about recognizing the words that appear repeatedly in academic English and understanding how they work in context.
The 100 words in this article are useful building blocks for TOEFL Reading, Listening, Speaking, and Writing preparation.
Start with 10 words per day. Review them regularly. Create your own examples. Most importantly, encounter the words in real English through academic articles, lectures, and TOEFL practice materials.
The more frequently you see and use these words, the faster they will become familiar.
