The first stage is to master the 2000 most frequently used words in English — the vocabulary foundation that gives you approximately 90% comprehension of any English text, and broadly aligns with IELTS Bands 3–4 and the A2 CEFR level, according to research by James Milton from Swansea University.

Every word is learned in the context of a real English sentence and a monolingual English definition — no reliance on translations. This trains you to think directly in English, which is exactly what the IELTS Reading and Listening tests require. Each flashcard also includes native audio and IPA so you learn the correct pronunciation for every word from day one, supporting your IELTS Speaking score at the same time.

This approach is grounded in Stephen Krashen’s “input hypothesis” — that learners acquire language fastest when they encounter it in context that is just slightly beyond their current level — and Michael Lewis’s “lexical chunks” research, which shows that words must be learned in sentence context, not in isolation, to be truly usable.

The second stage covers words ranked 2001–5000 by frequency — the vocabulary range that takes you from Band 4–5 performance toward Band 7 and above. Mastering these 3000 words pushes your comprehension toward 98% of written English, which means IELTS Reading passages stop feeling like obstacle courses and start feeling manageable.

Lexical Resource is one of the four IELTS Writing and Speaking band descriptors. To score Band 6 and above, examiners need to see a range of vocabulary used accurately and flexibly. Words 2001–5000 are precisely the words that signal lexical range — common enough to use naturally, uncommon enough to demonstrate breadth. Every flashcard presents the target word in a real sentence constructed entirely from the top 5000 words, so your learning builds cleanly on Stage 1.

The third and final stage targets the vocabulary and phrase patterns of formal academic English — the register that IELTS examiners assess at the highest band levels. This deck contains 43 high-frequency academic words that fall outside the top 5000 general frequency words (such as subjective, rationale, and adaptive), plus 272 essential academic phrases organized by rhetorical function.

The phrases cover every major move in IELTS Academic Writing — comparing and contrasting (“similar to”, “on the other hand”), hedging (“to some extent”, “it could be argued that”), structuring (“in addition to”, “as a consequence of”), specifying (“in terms of”, “with respect to”), and more. Two of the four IELTS Writing band descriptors — Lexical Resource and Coherence and Cohesion — are directly improved by this deck.

This deck was built using Speakada’s own research and curation, drawing inspiration from Paul Nation’s frequency research, Averil Coxhead’s Academic Word List from Victoria University of Wellington, and the Oxford Phrasal Academic Lexicon — then extending and refining them specifically for IELTS preparation.
