This article is part of our Complete IELTS Preparation Guide — all four skills covered with interactive practice exercises.
If you are preparing for IELTS Academic, studying at an English-language university, or writing professional reports, mastering academic English vocabulary is one of the highest-return investments you can make. The Academic Word List (AWL) — a research-based list of 570 word families that appear frequently across all academic disciplines — covers approximately 10% of the words in academic texts. This guide presents 200 of the most essential AWL words organised into 10 semantic categories, with collocations, example sentences, and gap-fill exercises you can use today. For more exam-focused vocabulary, see our companion article on IELTS vocabulary.
1. What Is the Academic Word List?
The Academic Word List was compiled by researcher Averil Coxhead from a corpus of 3.5 million words of academic written English across 28 subject areas. It was published in 2000 and remains the gold standard reference for academic vocabulary instruction. The AWL deliberately excludes the most common 2,000 words in English (covered by the General Service List) — which means all AWL words are above basic level.
The AWL is organised into 10 sublists based on frequency, with Sublist 1 containing the most frequent word families. Learning the words in this guide covers high-frequency items from Sublists 1 through 6, giving you breadth across all academic subjects. Each word family typically includes a noun, verb, adjective, and adverb form — all worth learning.
Word family example:
analyse (v) | analysis (n) | analytical (adj) | analytically (adv) | analyst (n, person)
Researchers analysed the data. / The analysis revealed a pattern. / Her approach was highly analytical.
2. The 200 Words: 10 Semantic Categories
Rather than presenting words alphabetically — which makes them hard to remember — we organise them into meaning-based clusters. Words in the same cluster share contexts and often appear together, making them easier to learn and use together.
Category 1: Analysis & Examination (20 words)
Key collocations: conduct an analysis, assess the impact, evaluate the evidence, examine the relationship, identify key factors, interpret the results, scrutinise closely
Category 2: Cause & Effect (20 words)
Key collocations: contribute to the problem, result in failure, have a significant impact, determine the outcome, attribute the cause to, lead to increased demand, positive/negative consequences
Category 3: Change & Trends (20 words)
Key collocations: a dramatic increase, fluctuate significantly, remain stable, a gradual decline, an upward trend, transform the economy, a steady rise in
Category 4: Comparison & Contrast (20 words)
Key collocations: compare and contrast, significant differences, in contrast to, a similar pattern, respectively higher/lower, proportionally greater, whereas Group A..., conversely
Category 5: Definition & Concept (20 words)
Key collocations: within the context of, the concept of sustainability, a theoretical framework, define the scope, underlying assumptions, test a hypothesis, a central principle
Category 6: Evaluation & Argument (20 words)
Key collocations: argue that, strongly claim, justify the approach, acknowledge the limitations, concede that..., refute the argument, advocate for change, highlight a key issue
Category 7: Evidence & Data (20 words)
Key collocations: the data demonstrate/show, the evidence suggests, the findings indicate, draw a conclusion, cite a source, statistical evidence, the results reveal, as illustrated by
Category 8: Method & Process (20 words)
Key collocations: adopt an approach, implement a strategy, conduct research/an experiment, establish a framework, utilise available resources, employ a technique, integrate different methods
Category 9: Structure & Organisation (20 words)
Key collocations: the main components, consist of several elements, focus on key aspects, provide a foundation for, constitute a major factor, outline the structure, summarise the findings
Category 10: Theory & Research (20 words)
Key collocations: conduct a study, review the literature, a theoretical model, statistically significant, empirical evidence, a valid and reliable instrument, a peer-reviewed source
3. Key Collocations Table
Collocations are the natural word partnerships in academic English. Knowing these will make your writing sound genuinely academic rather than forced. The following table presents the most important collocations from the AWL categories above.
| Verb | Natural object (collocation) | Unnatural version |
|---|---|---|
| conduct | conduct research / an experiment / a study / an interview | ~~make research~~ |
| draw | draw a conclusion / draw an inference | ~~make a conclusion~~ |
| reach | reach a conclusion / reach a consensus / reach an agreement | ~~arrive a conclusion~~ |
| provide | provide evidence / provide a framework / provide support | ~~give evidence~~ (acceptable but less formal) |
| raise | raise a question / raise awareness / raise an issue | ~~lift a question~~ |
| play | play a role / play a part / play a key function | ~~do a role~~ |
| pose | pose a challenge / pose a threat / pose a question | ~~create a question~~ |
| undergo | undergo a change / undergo treatment / undergo testing | ~~do a change~~ |
| exert | exert influence / exert pressure / exert control | ~~make influence~~ |
| gain | gain insight / gain access / gain understanding | ~~get insight~~ (acceptable but informal) |
✗ The researchers made an experiment to test the hypothesis.
✓ The researchers conducted an experiment to test the hypothesis.
✗ The data proves that the programme was successful.
✓ The data demonstrate / suggest / indicate that the programme was successful. (prove is too strong for most academic claims)
4. Word Family Practice
Learning a word in isolation is less effective than learning the whole word family. Here are the five most important AWL word families for IELTS and university writing, with all major forms:
| Verb | Noun (process/act) | Noun (person) | Adjective | Adverb |
|---|---|---|---|---|
| analyse | analysis | analyst | analytical | analytically |
| evaluate | evaluation | evaluator | evaluative | — |
| investigate | investigation | investigator | investigative | — |
| define | definition | — | definitive / defined | definitively |
| contribute | contribution | contributor | contributory | — |
| interpret | interpretation | interpreter | interpretive | — |
| implement | implementation | implementer | implemented | — |
| establish | establishment | — | established | — |
| identify | identification | — | identifiable | identifiably |
| assume | assumption | — | assumed | — |

6. How to Learn Academic Vocabulary Effectively
Having a list of 200 words is a starting point, not an endpoint. Research in vocabulary acquisition consistently shows that words need to be encountered multiple times across multiple contexts to move from passive recognition to active use. Here is an evidence-based learning routine:
- Learn in semantic groups (as in this guide) rather than alphabetical lists. Semantic grouping exploits the brain's associative memory and helps you recall which words go together.
- Learn collocations immediately. Never write just "significant" in your vocabulary notebook — write "a significant increase", "statistically significant", "significantly higher".
- Learn word families together. When you learn analyse, also learn analysis, analytical, and analyst on the same day.
- Use spaced repetition. Review new words after 1 day, then 3 days, then 1 week, then 1 month. Flashcard apps implement this automatically.
- Actively produce sentences. Write two or three of your own example sentences using each new word. Reading alone is not enough for active production in writing.
- Read widely. IELTS Academic reading passages, The Economist, The Guardian's science section, and university course textbooks are excellent sources of AWL in natural context.
- Do targeted gap-fill practice. LexFizz's Cloze Dropdown and Complete the Sentence exercises provide exactly this kind of practice.
