Academic English Vocabulary
20 essential academic words for B2–C1 learners — with definitions, example sentences, and free exercises for IELTS and university writing.
Academic English vocabulary is the set of formal, subject-neutral words that appear across many disciplines — in university essays, research papers, IELTS Academic tasks, and professional reports. These words are distinct from everyday conversational English and from subject-specific technical terms. Mastering them is one of the most efficient investments an intermediate or advanced learner can make.
Research by Dr Averil Coxhead, who developed the Academic Word List (AWL), shows that the 570 word families in the AWL cover approximately 10% of the words in academic texts. Words such as analyse, evaluate, hypothesis, methodology, and evidence appear in economics, history, science, and literature equally. Learning them once gives you a tool that works across all your studies.
This page presents 20 high-frequency academic words at B2–C1 level. Each word is given with its definition, an example sentence in an academic context, and its CEFR level. For many of these words, it is also important to know related word forms: analyse (verb), analysis (noun), analytical (adjective), analytically (adverb). Building word families like this dramatically expands your vocabulary range.
If you are preparing for IELTS Writing Task 2, Cambridge Advanced (CAE), or university essays, study this page alongside our School & University vocabulary and our blog post on IELTS vocabulary.

Frequently Asked Questions
What is academic vocabulary and why is it important?
Academic vocabulary refers to the formal words and phrases used in academic writing, lectures, and research — words that cut across many subject areas and appear in university essays, IELTS Academic tasks, and professional reports. Mastering academic vocabulary is essential for achieving a high score on IELTS Writing Task 2, Cambridge Advanced (C1), and for success in English-medium university courses.
What is the difference between analyse and evaluate?
To analyse means to examine something in detail by breaking it into its parts to understand how it works or why it happened. To evaluate means to make a judgement about the quality, significance, or value of something based on evidence. In academic essays, you are often asked to do both: analyse the evidence and then evaluate its implications.
What is the difference between a hypothesis and a thesis?
A hypothesis is a tentative explanation or prediction that can be tested through research: 'The hypothesis is that increased screen time reduces sleep quality.' A thesis is the central argument of an essay or research paper: 'The thesis of this essay is that...' In academic writing, your thesis is your main claim; your hypothesis is what you expect to find before conducting research.
What does it mean to cite a source in academic writing?
To cite a source means to acknowledge where a piece of information, idea, or quotation came from by including a reference in your text and a full entry in your bibliography. Correct citation avoids plagiarism and demonstrates that your argument is supported by evidence. Common citation styles include Harvard, APA, and MLA, depending on your institution and subject.
What is the difference between imply and infer?
To imply means to suggest something without stating it directly. The speaker or writer implies. To infer means to draw a conclusion from evidence or indirect signals. The reader or listener infers. A useful test: the author implies; the reader infers. For example: 'The data implies a correlation. We can infer from this that...' This distinction is tested in IELTS Reading and Cambridge Advanced.
What does methodology mean in academic writing?
Methodology refers to the system of methods and principles used to collect and analyse data in a research project. A methodology section in a dissertation or research paper explains how the research was conducted, why particular methods were chosen, and what the limitations of those methods are. It is different from 'methods', which describes specific tools or techniques used.
What is the difference between objective and perspective?
Objective (adjective) means based on facts rather than personal feelings; not influenced by bias. An objective analysis considers only the evidence. Perspective (noun) means a particular point of view or way of seeing a situation. Academic writing should be objective, but it may acknowledge multiple perspectives. Objective is the opposite of subjective (based on personal opinion).
What does it mean to deduce something?
To deduce means to reach a conclusion by reasoning from general principles or evidence. If all premises are true, the conclusion must follow: 'All organisms need water. Humans are organisms. We can therefore deduce that humans need water.' Deduction is a form of logical reasoning that moves from general to specific. It contrasts with induction, which moves from specific observations to general conclusions.
How do academic vocabulary words appear in IELTS?
Academic words from lists such as the Academic Word List (AWL) appear throughout IELTS Academic. In Reading, they appear in the texts themselves and in matching headings or True/False/Not Given tasks. In Writing Task 2, using precise academic vocabulary accurately — such as analyse, evaluate, conclude, and evidence — is essential for achieving a Band 7 or above in Lexical Resource.
What is the best way to learn academic vocabulary?
The most effective approach is to learn academic words in context — in sentences that show how and when each word is used. Start with Flash Cards on this page for initial recognition. Then practise writing your own sentences using the words. Reading academic articles, IELTS sample essays, and quality newspapers exposes you to these words in authentic contexts, which builds long-term retention.
