Vocabulary and Usage
The Vocabulary and Usage domain tests word knowledge in context: synonyms and antonyms, prefixes and suffixes, word families, idioms, commonly confused words and register. The exam asks you to choose the word that fits both meaning and grammar, and to explain why other choices fail.
Strategies
- Context clues: look for a definition, an example, a contrast signal (but, unlike) or a cause–effect signal (because, so).
- Word parts: un-, dis-, re-, pre-, -tion, -able, -less, -ous.
- Synonym choice: a synonym must fit the sentence's meaning, word class and tone.
- Register: formal writing avoids slang, SMS abbreviations and conversational fillers.
- Idioms: meaning is figurative, not literal.
Worked example
Sentence: "The manager's instructions were ambiguous, so the workers carried out two different tasks." Question: What does ambiguous most nearly mean? Reasoning: The result - two different tasks - shows the instructions could be understood in more than one way. So ambiguous means open to more than one interpretation. "Clear" is the opposite. "Angry" has no supporting clue. The answer must fit the cause–effect link signalled by "so".
Traps that cost marks
- Choosing a synonym that fits one sense of a word but not this sentence.
- Confusing affect/effect, principal/principle, stationary/stationery and advice/advise.
- Treating an idiom word by word.
- Ignoring whether the blank needs a noun, verb or adjective.
- Using informal words in a formal notice or letter.
Key points
- Read the whole sentence before choosing.
- Use contrast and cause–effect clues.
- Check word class as well as meaning.
- Learn common prefixes and suffixes.
- Replace slang with standard English in formal tasks.
