Introduction
Welcome to today’s lesson. In this session, we’ll be diving deep into the world of vocabulary questions in TOEFL iBT Reading. As you know, these questions can be quite challenging, but with the right techniques, you can tackle them effectively. So, let’s get started!
1. Context Clues
One of the most common types of vocabulary questions in TOEFL iBT Reading involves using context clues. The surrounding words or phrases can often provide hints about the meaning of an unfamiliar word. Pay close attention to the words before and after the target word, as they can offer valuable insights.
2. Word Roots
Understanding word roots can be a game-changer. Many English words have Latin or Greek origins, and knowing the meaning of these roots can help you decipher unfamiliar words. For example, the root ‘bio’ relates to life, so words like ‘biology’ or ‘biography’ are likely to be connected to the concept of life.
3. Prefixes and Suffixes
Similar to word roots, prefixes and suffixes can provide valuable clues. For instance, the prefix ‘un-‘ often indicates the opposite or negation of a word. So, if you come across a word like ‘unusual,’ you can infer that it means ‘not usual.’

4. Synonyms and Antonyms
Sometimes, the answer to a vocabulary question can be found in the options themselves. Look for synonyms or antonyms of the target word within the choices. This can help you eliminate incorrect options and narrow down your selection.
5. Part of Speech
Understanding the part of speech of a word can provide valuable insights into its meaning. For example, if a word is used as a noun in a sentence, it’s likely to represent an object, idea, or person. On the other hand, if it’s used as a verb, it indicates an action or state.
6. Pay Attention to Modifiers
Modifiers, such as adjectives or adverbs, can often provide clues about the meaning of a word. For example, if a word is described as ‘vibrant’ or ‘energetic,’ it’s likely to have a positive connotation. On the other hand, if it’s described as ‘dull’ or ‘lifeless,’ it’s probably negative.

7. Read the Entire Sentence
Sometimes, the meaning of a word becomes clearer when you read the entire sentence. The context of the sentence can help you understand the intended meaning of the word, even if you’re initially unfamiliar with it.
8. Use a Thesaurus
A thesaurus can be a valuable tool in your vocabulary arsenal. If you encounter an unfamiliar word, look it up in a thesaurus to find synonyms or alternative words that you’re more familiar with. This can give you a better understanding of the word’s meaning.
9. Practice with Sample Questions
The more you practice, the better you’ll become at answering vocabulary questions. There are numerous resources available online that provide sample questions similar to those in the TOEFL iBT Reading section. Make it a habit to regularly practice with these questions to hone your skills.
10. Read Widely
One of the most effective ways to improve your vocabulary is through extensive reading. Read a variety of materials, such as books, articles, and essays, to expose yourself to different words and their usage in context. This not only enhances your vocabulary but also improves your overall reading comprehension.
