Word lists evaporate. Learn one root, prefix, or suffix, and a family of words clicks — then keep them with daily review, quizzes, and a Mistakes deck for misses.
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!
It taught me how to read and write accurately and it is very useful. Whoever wants to get a good app, get this one. This is purely fun and absolutely amazing for any beginner to learn English.
