Stem Cards: Vocabulary Builder

Word lists evaporate. You memorize dozens of words for a test, and a week later most of them are gone — because every word was memorized on its own. Stem Cards teaches the parts words are built from instead: learn one root, prefix, or suffix, and a whole family of words starts making sense. One part learned, dozens of words unlocked. Features: - Flashcards that teach understanding, not memorization: Flip through interactive flashcards for stems, prefixes, and suffixes. Each card gives the meaning, example words, and audio pronunciation. - Daily Review & Mistakes — stop losing what you studied: Stems you missed, or flipped without grading, come back in a daily review queue, and missed stems stay in a Mistakes deck until you mark them "Got it." - Audio Pronunciation: Listen to clear audio pronunciation for every stem and example word to build listening and speaking confidence. - Vocabulary Builder & SAT/GRE Prep — get test-ready: Master Greek and Latin roots used in U.S. middle/high school curriculums and standardized test prep (SAT, ACT, GRE, TOEFL). - Challenge Quizzes — prove it to yourself: Test your retention with untimed and timed quizzes designed to challenge and cement your grasp of English word stems. - Instant Dictionary Search — never get stuck on an unfamiliar word: Quickly look up explanations, origins, and examples for any English stem, prefix, or suffix you encounter. - Favorites & Bookmarks — focus on your weak spots: Save difficult stems to revisit anytime for targeted, focused study sessions. - Stem Cards Pro — one-time purchase, no subscription: Remove ads, unlock full dictionary search, and save unlimited bookmarks. Why did I build this? Stem Cards is a project inspired by my son's middle school English teacher (Hat tip to Mrs. Wood!). She encouraged students to make index cards with English word stems, meanings, and drawings. I observed how quickly my son learned this way and how fun it was to make and use those cards. "I love this app! It's so easy to use and I can bring it with me everywhere I go. I'm learning so much!" - My 11yo son "Sometimes, when we are eating out, our family tests each other with the quizzes. It's a fun way to learn and have family time!" - My friend "In China, we used to memorize English words by heart. It was so hard! Now, with Stem Cards, I can learn English easily and fun!" - My friend in China Now, with Stem Cards, you can learn like him. Explore English word stems, play with flashcards, and test yourself. It's fun and easy!
