SAT Vocabulary Words

The current digital SAT Reading and Writing section uses short passages from literature, history and social studies, the humanities, and science. Its Craft and Structure questions ask students to determine the meaning of high-utility words in context and to choose the most logical and precise word or phrase. Vocabulary also supports evidence, inference, rhetorical synthesis, transitions, and clear Standard English expression across the section.

This independently authored 800-word beta curriculum is arranged in twenty-three pages of up to thirty-five words. Pages containing words 1–500 include five cloze questions drawn only from that enhanced range; words 501–800 remain fully visible and editable while the expanded practice layer is developed. Each row includes a passage-field label and an editable word-study note about a transparent affix, compound structure, capitalization, or dictionary base form. The list is an unofficial KSSR learning resource and is not endorsed by or affiliated with College Board. SAT is a registered trademark of College Board.

About the digital SAT

The digital SAT Reading and Writing section measures comprehension, analysis, synthesis, rhetoric, and command of language. Its Words in Context questions ask students to determine a word’s meaning or choose the most logical and precise word for a particular passage. That means SAT vocabulary study should focus on useful academic words, multiple meanings, tone, and exact usage—not on memorizing rare words in isolation.

Use this list as one part of SAT preparation. Read each example closely, compare near-synonyms, and notice how surrounding sentences control meaning. The lesson readings and questions are designed to practise the same habits of contextual reasoning, while official College Board questions remain the best guide to the test’s exact format.
