The process of preparing for the OET test can be daunting, yet the choice of words is key. The Essential OET medical vocabulary list for healthcare professionals is designed to assist nurses, doctors, pharmacists, and allied health professionals with effective communication and better results. No matter if you need your first go at taking the OET test or want to improve your OET band score, an adequate OET vocabulary list is the cornerstone for all sub-tests. This article gives you 100 carefully chosen words and tells you why having a good vocabulary is so important for the Occupational English Test. You will also find out how you can never forget them.
Why Vocabulary Matters in the OET
Unlike regular English exams, OET is a test for professionals. It tests English that people would really use in hospitals, wards, and pharmacies. This is why medical vocabulary for OET is so crucial for all four parts of the test.
During the OET listening part, you listen to consultations and lectures, in which words such as auscultation, palpitations, and discharge summary come up naturally. If you do not know what a certain word means, you waste time figuring it out and cannot understand the question that follows. In the OET reading section, you will be asked to read difficult medical texts and understand abbreviations used there.
Vocabulary is where the difference lies between earning an OET grade B vs. an OET grade C. Effective OET writing vocabulary allows you to write a professional, precise referral letter. Likewise, effective OET speaking vocabulary means being able to explain diagnoses to concerned patients in layman’s terms. This is all about showing flexibility in register use, empathy, and clinical accuracy. Bottom line: improving your OET writing and speaking vocabulary is a sure way to improve your scores to get that magic OET 350 mark.
The best part? You don’t need an extensive vocabulary list. You need the right common OET words used correctly and consistently. That is what the list below delivers.

Effective Strategies to Improve Vocabulary for the OET
Not only is it important to know the vocabulary to remember, but it is essential to have a good memory to retain the information learned. This is how one can expand his/her OET vocabulary successfully without getting tired. The following advice on preparing for the OET applies to any specialization like nursing, medicine, pharmacy, or physiotherapy.
- Create Mnemonics
Your brain remembers stories and patterns far better than isolated definitions. Memorization techniques for medical terms are fun ways to memorize boring terms. For instance, when memorizing the term “diuretic,” use the mnemonic “die-uretic; it will cause excessive urination.” It is also important for you to know that “hyper” is related to “high” and “hypo” is associated with “low.” Some medical terms use specific prefixes and suffixes along with their roots, which should be known for better comprehension. Once you know cardio (heart), -itis (inflammation), and -ectomy (removal), entire families of terminology open up.
- Engage in Active Learning
Passive reading rarely works. Retrieval practice, where one tries to remember the word by closing their notes on the list, is way more effective than rereading. Test oneself on the word, use it in another sentence, and/or try explaining its meaning to a co-worker. Each successful recollection process of that term means that you’re improving your memory in relation to that word.
- Practise with Real Life
Vocabulary in context is unforgettable. Use these terms during your actual shifts. Discussing the patient’s edema or explaining his/her prognosis involves contextual learning, which cannot be taught in textbooks. Listening to medical podcasts, reading clinical notes, and observing healthcare English vocabulary in the work environment help you learn the vocabulary in a natural manner. Practical experience is useful in learning how to shift from the use of formal language in OET writing to informal language while talking to patients.
- Use Flashcards for Repeated Practice
Spaced repetition is considered the best way to learn words. Programs like Anki create the opportunity to see a new word just as you are about to forget about it. In this way, you will do much better than by cramming everything in your mind at once. No matter if you use a program or write down everything manually, this principle stays the same. Create your own flashcard set based on the list of words presented here and spend ten minutes every day practicing with flashcards.
- Practice with OET Sample Tests and Materials
Words in isolation are not enough; you need to see them perform under exam conditions. Solving OET sample papers helps you understand how vocabulary is used in real-life tests, how the collocation of vocabulary in medicine is done, and where abbreviations in medicine would be required. Note how synonyms for commonly used terms are used, the connection words linking your ideas, and also the referral letter vocabulary and discharge summary vocabulary required in the test.
- Remain Curious and Motivated
Getting ready for the OET tests is quite a patient process since it can take some time to prepare. Celebrate yourself by recognizing the progress you made in terms of gaining new vocabulary and understanding why you chose to join the tests, whether for a work-related reason or relocating to another country.
