GRE Vocabulary Words

The GRE Verbal Reasoning measure asks test takers to understand and evaluate written material, analyze relationships among ideas, and use evidence within a sentence or passage. Reading Comprehension, Text Completion, and Sentence Equivalence all reward careful attention to connotation, contrast, logic, and precise word choice—not isolated memorization alone.

This independently authored 800-word beta curriculum prioritizes vocabulary identified in Magoosh’s official public GRE vocabulary ebook, then draws on advanced KSSR entries that have already passed English safety and structure audits. Additional official and public GRE references guide test alignment and editorial review. Overlap with SAT and advanced school-level vocabulary is intentional because the tests share academic language. Pages containing words 1–500 include five cloze questions; every word remains visible, editable in Vocabulary Studio, and available for private difficult/learned tracking. This unofficial resource is not endorsed by or affiliated with ETS.

About GRE Verbal Reasoning

The GRE Verbal Reasoning measure examines how well test takers understand and evaluate written material, recognize relationships among words and concepts, and analyze how parts of a sentence work together. Its three principal verbal question types are Reading Comprehension, Text Completion, and Sentence Equivalence.

Vocabulary matters on the GRE, but memorizing a definition is only the beginning. Strong preparation also connects each word to its connotation, common contrasts, near-synonyms, and role in an argument. Use the examples, readings, and quizzes here to practise choosing words from evidence in the sentence, then use official ETS material to learn the precise test format.
