Academic Word List:
The 570 Words That Open Academic English

The Academic Word List (AWL) identifies the 570 word families that appear across all academic disciplines — science, arts, law, commerce — and are rarely found in everyday English. Mastering the AWL is the single highest-leverage vocabulary investment for university study, IELTS, TOEFL, and academic reading.

What Is the Academic Word List?

The Academic Word List was compiled by Dr Averil Coxhead of Victoria University of Wellington and published in 2000. Coxhead analysed a 3.5-million-word corpus of written academic English spanning 28 subject areas across four broad disciplines: arts, commerce, law, and science. Her goal was to identify vocabulary that appears frequently across all academic disciplines — not the specialist terminology of individual fields, and not the common everyday words that everyone already knows.

The result is 570 word families organised into 10 sublists by frequency. Each family consists of a head word (e.g. "analyse") plus its morphological derivatives (analysis, analytical, analytically, analyst). Learning one head word in the AWL gives you access to an entire family of related forms.

Two conditions had to be met for a word family to be included in the AWL: the head word had to appear in at least 15 of the 28 subject areas (breadth condition), and with a minimum frequency across the corpus (frequency condition). This ensures that AWL words are genuinely cross-disciplinary — they appear in biology textbooks, economics papers, history journals, and legal documents alike.

The AWL does not include the most frequent 2,000 word families in English (the General Service List). Those are assumed to be known. The AWL starts where everyday vocabulary ends.

How Much Academic Text Does the AWL Cover?

Despite containing only 570 word families, the AWL covers approximately 10% of all words in academic text. This is a remarkable concentration of utility for a relatively small list. To put it in perspective:

Vocabulary resourceWord familiesCoverage of academic text
General Service List (most frequent 2,000)2,000~80%
Academic Word List (AWL)570~10%
GSL + AWL combined~2,570~90%
Next 3,000 most frequent words3,000~4–5%
Full coverage (95%+ of academic text)~8,000–9,00095%+

The 90% coverage provided by the GSL and AWL together means that a learner who knows these ~2,570 word families encounters one unknown word every 10 words in academic text — workable, but requiring significant inferential effort. Reaching the 95–98% coverage needed for comfortable academic reading requires an additional 6,000+ word families beyond the AWL.

The AWL's 10 Sublists

The AWL is divided into 10 sublists by frequency. Sublist 1 contains the 60 most frequent word families in the corpus; Sublist 10 contains the 30 least frequent. The first six sublists — 390 word families — account for the vast majority of AWL encounters in academic text and should be mastered before the later sublists.

Sample AWL Words: Sublist 1 in Depth

Sublist 1 is the highest priority. Below are eight Sublist 1 words with their definitions and usage notes — the kind of depth that produces durable learning, not just passive recognition.

Analyse
verb · AWL sublist 1
To examine something in detail in order to understand it or explain it. Family: analysis (n), analytical (adj), analytically (adv), analyst (n)
Constitute
verb · AWL sublist 1
To be or make up (a part of a whole). Distinguished from "comprise": the parts constitute the whole; the whole comprises the parts
Derive
verb · AWL sublist 1
To obtain or originate from a source. Key academic usage: "X is derived from Y"; "findings derive from the data". Family: derivation (n), derivative (adj/n)
Evident
adj. · AWL sublist 1
Plain or obvious; clearly seen or understood. Collocations: "it is evident that", "as is evident from", "self-evident". Family: evidence (n), evidently (adv)
Interpret
verb · AWL sublist 1
To explain the meaning of; to understand in a particular way. Critical in academic writing and IELTS/TOEFL tasks. Family: interpretation (n), interpretive (adj)
Significant
adj. · AWL sublist 1
Important; large or notable enough to be noteworthy. In statistics: showing that a result is unlikely to be due to chance. Common collocation: "statistically significant"
Vary

To be different; to change or cause to change. Essential for IELTS Task 1 data description. Family: variable (n/adj), variation (n), varied (adj), various (adj)
Theory
noun · AWL sublist 1
A system of ideas to explain something; in science, a well-substantiated explanation. Distinguish from "hypothesis" (unverified). Family: theoretical (adj), theorise (v), theorist (n)

Word Families: Why You Learn 4 Words for the Price of 1

The AWL is organised by word families rather than individual words. This is not a technicality — it fundamentally changes how you should study. When you learn the head word "analyse," you are not learning one word; you are learning a cluster of related forms that all derive from the same root and carry overlapping meanings:

FormExampleTypical context
analyse (verb)"We analyse the data using regression methods."Methodology sections
analysis (noun)"The analysis reveals three key patterns."Results and discussion sections
analytical (adj)"The report takes an analytical approach."Descriptions of method/approach
analytically (adv)"The text can be read analytically or emotionally."Comparisons of approach
analyst (noun)"Market analysts predict continued growth."News, economics, policy texts

When studying AWL words, always learn the full word family. Use a word web: put the head word in the centre, add all family members around it, and write one example sentence for each. This produces active knowledge (the ability to use words in writing and speaking) rather than passive recognition alone.

AWL and Tier 2 Vocabulary

The AWL overlaps significantly with what vocabulary researchers Isabel Beck, Margaret McKeown, and Linda Kucan call Tier 2 vocabulary — words that are: high-frequency in mature language use; low-frequency in everyday conversation; and cross-disciplinary rather than domain-specific. Examples: "apparent," "significant," "contrary," "establish," "maintain."

Tier 2 words are contrasted with Tier 1 (basic everyday words: house, run, happy) and Tier 3 (domain-specific technical terms: mitosis, jurisprudence, depreciation). Tier 2 words are the most productive study target because they appear across reading and listening contexts — every academic subject, every quality newspaper, every formal correspondence. The AWL is effectively a curated Tier 2 list calibrated for academic English specifically.

For SAT vocabulary study, the AWL is directly relevant to the SAT's focus on "words in context" in academic passages — see the SAT & GRE Vocabulary guide for how Tier 2 vocabulary maps to the current SAT test format.

AWL and Exams: IELTS, TOEFL, SAT, GRE

The AWL is relevant to every major academic English exam:

ExamAWL relevancePriority sublists
IELTS AcademicVery high — AWL words appear directly in Reading passages and are expected in Writing Task 2 essays. Lexical Resource scoring rewards AWL usage.Sublists 1–6 (all essential)
TOEFL iBTVery high — TOEFL Reading passages are drawn from academic textbooks where AWL density is 8–12%. Explicit vocabulary questions often target AWL words.Sublists 1–6
SAT (current)High — SAT Reading passages are academic non-fiction where Tier 2 / AWL vocabulary is common. "Words in context" questions often target AWL words.Sublists 1–4
GREMedium — GRE vocabulary extends beyond the AWL into rarer, more Latinate words. The AWL is a necessary foundation but not sufficient for high GRE Verbal scores.Sublists 1–3 as a base; then GRE-specific word lists

AWL for University Study

University reading requires not just knowing AWL words but using them correctly in written work. Academic writing is assessed partly on vocabulary range and precision — and AWL words are the vocabulary of precision in academic writing. Understanding the difference between "significant" and "major," or between "indicate" and "prove," is the difference between a student who sounds academic and one who merely recites information.

AWL in different disciplines

The AWL's cross-disciplinary design means the same words appear in every field, but their collocations and usage patterns vary by discipline:

How to Study the AWL Effectively

1. Work through sublists in order

Start with Sublist 1 (60 word families) and master it before moving to Sublist 2. The frequency ordering means that Sublist 1 words will appear more often in every academic text you read — every new AWL word you encounter in reading will reinforce a word you have already studied. Do not skip to later sublists because specific words there interest you.

2. Learn word families, not just head words

For each AWL entry, identify all the word family members (noun, verb, adjective, adverb) and write an example sentence for each form. This is how you develop the grammatical flexibility that IELTS and TOEFL Writing tasks require — knowing when to use "analysis" versus "analytical" versus "analyse" in the same argument.

3. Learn collocations alongside definitions

Academic vocabulary has strongly patterned collocations that are different from everyday collocations. "Conduct" collocates with "research," "survey," "experiment" — not with "work" (in formal academic writing). "Significant" collocates with "difference," "increase," "proportion," "effect" — not with "issue" (which is informal register). An Oxford Collocations Dictionary or academic corpus tool (like the Corpus of Contemporary American English) will help you learn these patterns.

4. Use the AWL in your own writing immediately

Reading exposure alone produces slow AWL acquisition. The fastest route to active AWL knowledge is using the words in your own writing. Set yourself the task of writing a 200-word academic paragraph on any topic and deliberately incorporating five AWL words from Sublist 1. This forces you to engage with the words' grammatical behaviour and collocational patterns rather than just their definitions.

5. Read academic text regularly

Each AWL word you encounter in authentic academic reading deepens your knowledge of it — its typical context, its most common collocates, its register. Reading one academic article per week, in any discipline, provides hundreds of AWL encounters per session. OpenStax textbooks, PubMed abstracts, and JSTOR accessible articles are all appropriate sources at IELTS/TOEFL preparation level.

Frequently Asked Questions

What is the Academic Word List (AWL)?

The AWL is a list of 570 word families compiled by Dr Averil Coxhead (2000) from a 3.5-million-word corpus of academic texts. These words appear frequently across all academic disciplines and are rarely found in everyday English — making them the most important vocabulary for university study, IELTS, TOEFL, and academic reading.

How much of academic text does the AWL cover?

The AWL covers approximately 10% of all words in academic text. Combined with the most frequent 2,000 word families (the General Service List, which covers ~80% of academic text), knowing the AWL brings total coverage to ~90%. Comfortable academic reading requires 95–98% coverage, so the AWL is necessary but not sufficient — you also need the broader vocabulary that comes from sustained academic reading.

Is the AWL still current and relevant?

Yes. The AWL was published in 2000 and remains the most widely used academic vocabulary resource in English language teaching. Subsequent research (including Gardner and Davies' Academic Vocabulary List, 2013, which covers 3,000 word families) has confirmed that the core AWL words continue to appear at high frequencies in contemporary academic text. The original 570 families remain the standard starting point for academic vocabulary study.

Should I learn all 570 AWL words?

Yes, for academic or exam purposes — but in order. Sublists 1–6 (390 word families) are the highest priority and should be mastered for IELTS Academic, TOEFL, and university study. Sublists 7–10 are less frequent and have lower return per study hour, but they are still worth covering if you are preparing for academic writing at degree level or above.

How is the AWL different from general English vocabulary lists?

General English word lists (like the General Service List) are based on frequency in all English usage — newspapers, fiction, everyday conversation, as well as academic writing. The AWL is specifically calibrated to academic writing, excluding both common everyday words (already in the GSL) and subject-specific technical terms. This makes it uniquely useful for academic preparation: it is precisely the vocabulary that academic texts assume you know beyond the basics.
