Why Frequency-Based Study Beats Random Vocabulary Lists
Frequency studies of English corpora consistently show a small core vocabulary doing the bulk of the work. Roughly 100 words make up half of typical conversation; the top 1,000 cover three-quarters. That means every word you learn from the top tiers compounds — you encounter it, recognise it, and reinforce it dozens of times a week without trying. Words at the bottom of the frequency curve might appear once a month. Studying both tiers with the same intensity wastes effort.
Each card here pulls its data — definition, IPA, example sentences, common mistakes — from the same dictionary entry. Tap the dictionary link on the back of any card to see all meanings, synonyms, etymology, and word forms.

FAQ
Why study by frequency rank?
Frequency-tier study delivers the fastest comprehension gains. The top 1,000 English words cover roughly 75% of conversational text; the top 3,000 cover ~90%. Drilling these first means almost everything you read becomes more accessible.
How long should I spend on the Rare tier?
Plan for 20 cards per day. At that rate the deck takes 3 to 5 weeks. Mix in CEFR-level decks to add structure to topical learning alongside frequency.
Should I do all five tiers?
Top 1,000 and top 3,000 are essential for everyone. Top 5,000 is high-value for serious learners. Top 10,000 and rare entries are diminishing returns — skip unless you read widely or work in language-heavy fields.
