Vocabulary Building: The Academic Word List

570 Power Words That Unlock Band 7+

Open interactive version (quiz + challenge)

Real-world analogy

Think of your vocabulary like a wardrobe. Everyday words (good, bad, big, small) are like t-shirts and jeans — fine for casual situations but not for a job interview. Academic vocabulary is your suit collection — words like 'significant', 'analyze', 'demonstrate', and 'facilitate' dress your ideas professionally. The Academic Word List (AWL) is like a curated capsule wardrobe: 570 essential words that appear across all academic subjects and dominate IELTS texts.

What is it?

The Academic Word List (AWL) is a collection of 570 word families that appear frequently across all areas of academic writing. For IELTS candidates, mastering these words is the fastest path to improving Reading comprehension and Writing/Speaking vocabulary scores. Combined with collocations, synonyms, and word-part knowledge, the AWL forms the core vocabulary toolkit for Band 7+.

Real-world relevance

A researcher at Victoria University of Wellington found that students who learned the AWL could understand an additional 10% of any academic text they encountered. For IELTS, this translates to roughly 3-4 more correct answers in Reading. One student reported jumping from Band 6 to Band 7 in Reading simply by spending six weeks systematically learning the AWL with collocations.

Key points

What is the Academic Word List (AWL)? — Created by Averil Coxhead in 2000, the AWL contains 570 word families that frequently appear in academic texts across all disciplines. These words make up about 10% of academic writing — meaning roughly 1 in 10 words in an IELTS Reading passage comes from this list. Learning them is the single most efficient way to boost your IELTS vocabulary score.
High-Frequency AWL Sublist 1 — The most common 60 AWL word families include: analyze, approach, area, assess, assume, authority, available, benefit, concept, consist, constitute, context, contract, create, data, define, derive, distribute, economy, environment, establish, estimate, evidence, export, factor, finance, formula, function, identify, income, indicate, individual, interpret, involve, issue, labour, legal, legislate, major, method, occur, percent, period, policy, principle, proceed, process, require, research, respond, role, section, sector, significant, similar, source, specific, structure, theory, vary. Memorize these first!
Learning Words in Families — Do not learn words in isolation — learn the whole family. For 'analyze': analysis (noun), analytical (adjective), analytically (adverb), analyst (noun). This multiplies your vocabulary by 3-4x instantly. IELTS Reading often tests your ability to recognize different forms of the same word across a passage. One word family can give you 4-6 usable words.
Collocations — Words That Go Together — Native speakers do not just know words — they know which words naturally pair together. 'Make a decision' (NOT 'do a decision'), 'conduct research' (NOT 'make research'), 'pose a threat' (NOT 'give a threat'). Using correct collocations is what separates Band 6 ('The graph has a big increase') from Band 7 ('The graph shows a significant increase').
Synonyms and Paraphrasing — IELTS rewards paraphrasing — restating ideas using different words. Build synonym clusters: important = significant, crucial, vital, essential, paramount. Increase = rise, grow, surge, escalate, soar. Problem = issue, challenge, concern, drawback, obstacle. Having 4-5 synonyms for common concepts lets you paraphrase fluently without repeating yourself.
Context Clues for Unknown Words — In IELTS Reading, you will encounter unfamiliar words. Use context clues to guess meaning: definition clues ('Photosynthesis, the process by which plants convert sunlight into energy...'), contrast clues ('Unlike her gregarious sister, Maria was shy'), example clues ('Legumes such as beans, lentils, and peas'), and word-part clues (un- = not, re- = again, -tion = noun).
Word Parts: Prefixes and Suffixes — Prefixes change meaning: un- (not), re- (again), pre- (before), over- (too much), under- (too little), mis- (wrongly), dis- (opposite). Suffixes change word class: -tion/-sion (noun), -ment (noun), -ous/-ive/-al (adjective), -ly (adverb), -ize/-ify (verb). Knowing 20 common prefixes and 20 suffixes helps you decode hundreds of unfamiliar words on test day.
Vocabulary for IELTS Writing Task 1 — Task 1 needs specific trend vocabulary: increase/decrease (rise/fall, grow/decline, surge/plummet), stability (remain steady, plateau, level off), speed (gradually, steadily, sharply, dramatically, slightly), approximation (approximately, roughly, just over, nearly). These words are non-negotiable for Band 7+ in Task 1.
Active vs Passive Vocabulary — Passive vocabulary = words you can recognize when reading or hearing. Active vocabulary = words you can correctly USE in writing and speaking. IELTS tests both. For Reading and Listening, passive is enough. For Writing and Speaking, you need active mastery. Strategy: learn words in sentences, not just definitions. Write example sentences for every new word you learn.

Line-by-line walkthrough

1. This reference organizes key AWL vocabulary into functional categories for IELTS use.
2. Data description words (significant, proportion, majority) are essential for Writing Task 1 — you use these to describe charts and graphs.
3. Arguing and discussing words (controversial, advocate, consequence) power Writing Task 2 essays where you present and defend opinions.
4. Process words (constitute, facilitate, implement) help describe systems and procedures in both Reading comprehension and Writing.
5. The word family example shows how 'economy' generates 7 usable words across all parts of speech — learning families multiplies your vocabulary.
6. Collocation examples highlight the difference between natural English (conduct research) and common errors (make research).
7. Synonym clusters give you 5-6 alternatives for common concepts, enabling the paraphrasing skill that IELTS rewards heavily.
8. Notice how each 'wrong' collocation sounds awkward to native speakers — these fixed pairings must be memorized, not guessed.

Spot the bug

The goverment has conducted a signifcant research into the economical impact of tourism. The evidences suggest that tourism is benefitial for the local economics. Many experts have drew the conclusion that further investation is needed to maximise the potencial of this sector.

Need a hint?

Look for spelling errors, wrong word forms, article errors with uncountable nouns, and incorrect verb forms.

Show answer

Errors: 1) 'goverment' → 'government' (spelling). 2) 'signifcant' → 'significant' (spelling). 3) 'a significant research' → 'significant research' (research is uncountable — no article). 4) 'economical' → 'economic' (economical means 'cheap/thrifty'; economic relates to the economy). 5) 'evidences' → 'evidence' (uncountable noun). 6) 'benefitial' → 'beneficial' (spelling). 7) 'economics' → 'economy' (economics is the study/field; economy is the system). 8) 'drew' → 'drawn' (present perfect needs past participle: have drawn). 9) 'investation' → 'investigation' or 'investment' (not a real word). 10) 'potencial' → 'potential' (spelling).

Explain like I'm 5

Imagine you know the words 'happy', 'sad', 'good', and 'bad'. Those are like crayons — you can color a picture, but it will be simple. Now imagine you also know 'delighted', 'devastated', 'exceptional', and 'dreadful'. Those are like a giant box of 64 crayons with all the special colors! This special word list is like getting that big crayon box — it gives you the fancy words that make your IELTS writing and speaking colorful and impressive.

Fun fact

The average IELTS Reading passage contains about 900 words, of which roughly 90 come from the Academic Word List. That means if you master the AWL, you already know 10% of every passage before you even read it! Research shows AWL knowledge is the strongest single predictor of IELTS Reading scores.

Hands-on challenge

Choose 10 words from AWL Sublist 1 (analyze, approach, benefit, concept, environment, establish, evidence, method, significant, theory). For each word: (1) write the full word family (noun, verb, adjective, adverb forms), (2) write a natural collocation, and (3) write an IELTS-style sentence using the word. You should end up with at least 40 word forms and 10 strong sentences.
