How to Improve Your Vocabulary

Your vocabulary is comprised of all the words you know: words you can read, write, speak, define, and recognize. Improving your vocabulary provides access to a broader range of verbal expression, and helps you perceive the nuances of the English language. When reading a novel or a newspaper article, your grasp of uncommon words allows you to understand the writer's finer points. When writing a paper or essay, your careful articulation makes you sound insightful, original, and authoritative. While using a dictionary or thesaurus can help you vary diction on the go, study tools can help you expand your word retention and recall. This will help you in the classroom, on standardized tests, and in everyday conversation. This guide is a collection of dozens of links to vocabulary resources that we have researched, categorized, and annotated in order to help you improve your vocabulary and test-taking skills.
