ESLBuzz Flashcards — Free Vocabulary Practice Decks
Practice English vocabulary with 4735+ flashcards organised by CEFR level, topic, and part of speech. Every card is sourced from the ESLBuzz dictionary — definitions, IPA, example sentences, and common mistakes are pulled from the same canonical entry. Use spaced repetition (SM-2 algorithm) to lock vocabulary into long-term memory.
Study by CEFR Level
Pick the deck matching your current level. CEFR is the standard European framework for language proficiency — from A1 (beginner) through C2 (near-native).
Study by Topic
Topic decks group dictionary entries by domain — useful for specialised vocabulary like medical, legal, technical, or business English.
Practice by Part of Speech
Drilling a single part of speech at a time builds intuition for how those words combine with surrounding text. Verbs deserve their own session — pair the verbs deck with the conjugator tool to learn forms together.
Study by Frequency Tier
Frequency-tier decks group words by how often they appear in real English. The top 1,000 words cover roughly 75% of conversational text — start there for the fastest comprehension gains.
Study by Register
Register decks group words by formality. Formal vocabulary belongs in academic and professional writing; informal in everyday conversation. Knowing which is which separates fluent speakers from advanced learners.
Curated Collections
Themed collections built from dictionary metadata — irregular verbs, commonly confused word pairs, top ESL mistakes, phrasal verbs. High-leverage decks that target specific stumbling blocks.
How Spaced Repetition Works
When you flip a card, you rate how well you knew it: Try again, Got it, or Easy. The SM-2 algorithm — used by Anki and SuperMemo — picks the next review interval based on your rating. Cards you struggle with come back sooner; cards you know well wait longer. The result: you spend study time only on words your brain is about to forget.
- Day 1: See a new card. Rate it after flipping.
- Day 2-6: Card returns at growing intervals (1 day, 6 days, then ease-factor × previous).
- Long term: Cards you keep rating Easy graduate to monthly review; cards you struggle with stay in daily rotation.
Frequently Asked Questions
How do ESLBuzz flashcards work?
Each card draws its content from the ESLBuzz dictionary — definition, IPA, example sentences, and common mistakes. The SM-2 spaced repetition algorithm schedules each card for review based on how well you knew it.
Which deck should I start with?
Start with the CEFR deck that matches your current level. If you don't know your level, the A1 deck covers the most common 200-400 English words — perfect for beginners. Use topic decks once you have a level foundation.
Can I study without an account?
Yes. Progress is stored in your browser using a session ID, so you can keep practicing anonymously. To sync across devices, sign in with an ESLBuzz account.
How many cards should I study a day?
Aim for 15-20 cards a day for steady progress. Consistency matters more than volume — daily 15-card sessions outperform weekly 100-card sprints.
