Browse by list size
Words in Context (Craft and Structure โ 28%)
Every vocabulary question embeds the word in a short passage. You must choose the meaning that fits that specific context โ not the word's most common dictionary definition.
Transitions (Expression of Ideas โ 20%)
Transition words appear as the four answer choices. You must know what relationship each transition signals (contrast, addition, result, example) to choose correctly.
How to Study SAT Vocabulary Effectively
Do: Learn words in context
Read each example sentence carefully. Note how the word functions grammatically (is it a verb, noun, or adjective here?) and what tone or connotation the context implies.
Do: Learn multiple meanings
Many SAT vocabulary questions test words in unusual meanings. A word like "champion" (to support) or "novel" (new) appears as a trap because students know only the common meaning.
Don't: Memorize isolated definitions
The SAT never asks "what does X mean?" in isolation. It always tests meaning in context. Isolated definition memorization misses the contextual nuance the test actually measures.
Do: Memorize transition word categories
For Transitions questions, you don't need full definitions โ you need to know the category (contrast, addition, result, example) each word belongs to. This is a learnable system that takes only a few hours to master.
Do: Learn tone and attitude words
Questions asking about an author's attitude, tone, or perspective are common. Knowing words like "sardonic," "measured," "polemical," and "dispassionate" lets you choose the answer that most precisely captures an author's voice.
Do: Practice on full-length tests
The best vocabulary practice is encountering words in real SAT passages. Review every vocabulary question you miss to understand why the correct answer fits the specific context better than your choice.
