Medical English for Working Professionals: Roots, a Learning Path, and Listening Resources
On this page
You read "hepatitis" in a document and know right away it means viêm gan. But in a video case discussion with a foreign colleague, they say a sentence with that word at normal speed, and you freeze for a couple of seconds because the sound doesn't match the word you've read before.
The problem isn't that you lack vocabulary — it's that most of those words you recognize by eye, not by ear. Skim past "nephrectomy" and you still understand it means kidney removal, but hear someone say it out loud, with stress falling somewhere you didn't expect, and your ear processes it as an unfamiliar word.
Medical English has one convenient feature: most terminology is built from about two dozen Latin and Greek roots. This article starts with the hard part first — stress and pairs of words that sound alike — then moves to vocabulary tables and a roadmap for people already working.

Why medical English is harder than everyday English
Most of the everyday English words you learned before have Anglo-Saxon roots: short, familiar to the ear. Medical vocabulary is built from Latin and ancient Greek roots, so a native English speaker who hasn't studied medicine doesn't understand "nephrectomy" either. You're not at any disadvantage compared to them on this point.
The second difficulty: words that look familiar but whose meaning is completely different from everyday usage. "Acute" in ordinary life suggests sharpness; in medicine it just means a severe, sudden-onset condition. "Benign" sounds like a compliment for gentleness; here it means a tumor is non-cancerous.
Stress patterns and the spots where the ear tends to slip
Take "tachycardia" as an example. Look at the spelling and it makes sense right away: tachy (fast) plus cardia (heart), fast heart rate. But it's pronounced /ˌtæk.ɪˈkɑr.di.ə/, with the stress falling on "car," not on "tachy" the way you'd read it from the spelling. This pattern repeats in most words with the suffixes -itis, -ectomy, -emia, -osis: the stress clusters near the suffix, one or two syllables from the end, rather than on the first root.
This mistake only shows up when listening and when speaking. It's also one reason why Vietnamese learners have weaker listening comprehension than their vocabulary should allow.
The two roots "nephr/o" (kidney) and "neur/o" (nerve) sound nearly the same when spoken quickly, so "nephrology" and "neurology" are easy to mix up if you're not used to the /fr/ consonant cluster.
The three suffixes "-otomy," "-ostomy," "-ectomy" mean completely different things: cutting open, creating an opening, and removing entirely. But they end almost the same way, and listening carelessly leads to picking the wrong one.
A test result that comes back "positive" sounds like good news in everyday language, but for many tests, a positive result is actually the bad news, while "negative" is the good one.
Abbreviations follow no shared pronunciation rule. A single line of clinical notes can contain BP, HR, IV, NPO one after another, each read letter by letter, while some other abbreviations are read as a single word. There's no way to guess in advance — you just have to get used to hearing each specific one.
Dictation practice so words don't slip away
A word list you read once and set aside won't leave much behind a week later. What sticks is usually the words you once misheard and then corrected yourself, and that's exactly how dictation practice works: listen to a conversation or medical news segment, transcribe it sentence by sentence, compare against the original, and see exactly which word you got wrong. If you're not familiar with the process yet, check out the article 5 steps to effective dictation practice.
In connected speech, medical terms also get swallowed and linked together just like ordinary words. In the sentence "She was referred to cardiology," the word "to" gets reduced to the point of almost disappearing entirely. The article connected speech, the secret to understanding native speakers explains this mechanism in more detail.
Listening material also needs to match the right topic, since podcasts outside your field only train general listening skills. The article learning by topic, how to choose the right podcast explains how to choose, and health content is available in WELE's podcast library.
Medical vocabulary grouped by topic
The five tables below are organized by purpose. Read the first table carefully — it's the key to the rest.
Roots and suffixes you must know by heart
Master the roughly two dozen building blocks below, and you can work out the meaning of hundreds of words you've never encountered, instead of learning each medical term one by one.
| Word / element | Pronunciation | Meaning | Example sentence |
|---|---|---|---|
| cardi/o | /ˈkɑr.di.oʊ/ | heart | "The ECG showed signs of tachycardia, so the cardiologist ordered further tests." |
| derm/o | /ˈdɜr.moʊ/ | skin | "She was referred to dermatology for a persistent rash." |
| gastr/o | /ˈɡæs.troʊ/ | stomach | "He's had gastritis for two weeks and still can't keep food down." |
| hepat/o | /ˈhep.ə.toʊ/ | liver | "Elevated liver enzymes are consistent with hepatitis." |
| nephr/o | /ˈnef.roʊ/ | kidney | "The nephrologist recommended a kidney biopsy." |
| neur/o | /ˈnʊr.oʊ/ | nerve | "Neurology is booked out for the next three weeks." |
| oste/o | /ˈɑs.ti.oʊ/ | bone | "Osteoporosis was noted on the bone density scan." |
| pulmon/o | /ˈpʊl.mə.noʊ/ | lung | "The chest X-ray was sent to pulmonology for review." |
| -itis | /ˈaɪ.tɪs/ | inflammation | "Arthritis in both knees limits how far she can walk." |
| -ectomy | /ˈek.tə.mi/ | surgical removal | "She's scheduled for an appendectomy tomorrow morning." |
| -otomy | /ˈɑt.ə.mi/ | surgical incision, cutting into | "A tracheotomy was performed to secure the airway." |
| -ostomy | /ˈɑs.tə.mi/ | creating an opening to the outside of the body | "He's recovering well after the colostomy." |
| -algia | /ˈæl.dʒə/ | pain condition | "The patient reported neuralgia radiating down the left arm." |
| -osis | /ˈoʊ.sɪs/ | abnormal condition, usually ongoing | "The pathology report confirmed cirrhosis." |
| -emia | /ˈi.mi.ə/ | a condition related to the blood | "Her labs came back showing anemia." |
| hyper- | /ˈhaɪ.pər/ | high, excessive | "He was diagnosed with hypertension last year." |
| hypo- | /ˈhaɪ.poʊ/ | low, deficient | "Watch for signs of hypoglycemia after the insulin dose." |
| brady- | /ˈbræd.i/ | slow | "The monitor picked up bradycardia overnight." |
| tachy- | /ˈtæk.i/ | fast | "Tachycardia can be a sign of anxiety or something more serious." |
Try assembling four commonly encountered words:
- hepatitis = hepat/o (liver) + itis (inflammation), meaning liver inflammation.
- nephrectomy = nephr/o (kidney) + ectomy (removal), meaning surgical removal of the kidney.
- tachycardia = tachy (fast) + cardia (related to the heart), meaning fast heart rate.
- hypoglycemia = hypo (low) + glyc (blood sugar) + emia (condition of the blood), meaning low blood sugar.
When you come across a long, unfamiliar word, don't reach for the dictionary right away. Break it into pieces, guess the meaning first, then check the dictionary to verify.

How to study once you're already wearing the white coat
Medical students learn terminology to pass exams. Someone already working needs it in three different places: reading medical literature and orders, listening in on consultations with foreign patients, and presenting a case. Those three things call for three different ways of practicing.
- Stage one, reading to regain speed. Each week pick a condition you see often, read an article about it written for healthcare staff, then read a piece written for patients on the same topic. Write down each pair, the technical term and its everyday counterpart.
- Stage two, catching the spoken word, not just the text. Each week, one clinical podcast episode with a transcript: listen to two minutes, transcribe it sentence by sentence, then check it against the transcript. Most of the gap isn't in the terminology but in the very ordinary connecting words around it.
- Stage three, being able to say a case out loud. Each week, build a ninety-second presentation for a case you just saw, following the familiar order: age and presentation, course of illness, examination and lab findings, management plan. Record it, listen back, then cut out the places where you stumbled.
Sources should be prioritized where expertise is kept current and a transcript is available.
- Merck Manuals (merckmanuals.com): free and open, each topic has two versions, one for healthcare professionals and one for patients, so you can read the same content at two levels of formality.
- Core IM (coreimpodcast.com): an internal medicine podcast, each episode comes with a full transcript, timestamps, and a list of references.
- The Clinical Problem Solvers (clinicalproblemsolving.com): the episodes are scenes of doctors presenting a case and reasoning through the diagnosis on the spot, exactly what you practiced in stage three, and the site has illness scripts in written form to cross-check against.
- This Podcast Will Kill You (thispodcastwillkillyou.com): two epidemiologists tell the history and mechanism of a disease in each episode, at a slower pace than clinical podcasts, and the site has a transcripts section.
Frequently asked questions
How much medical vocabulary should I learn to be able to read professional materials?
There's no fixed number, and the goal isn't a word count anyway. Once you know the core root words in the first table, you can infer the meaning of most new words.
How is medical English different from pharmacy or nursing English?
The Latin and Greek roots are shared across all three. But nursing leans toward care procedures by shift, while pharmacy leans toward dosage forms and drug interactions, so mastering the common part first will get you there faster.
Do I need to learn IPA symbols to pronounce medical terms correctly?
You don't need to be able to read all of IPA. But each time you learn a new word you should mark which syllable carries the stress, because as covered in the stress section above, that's where mistakes happen far more than with individual sound pronunciation.
Is learning medical vocabulary through movies or medical series effective?
Watching shows helps your ear get used to context, but the dialogue is scripted for drama and doesn't accurately reflect how people actually talk. Listening to content with a transcript you can cross-check will be closer to the real thing.
How do I know I'm hearing the stress wrong if there's no one to correct me?
Transcribe it, then compare word by word against the original. Dictation listening practice does exactly that, the reference transcript points straight to the word you misheard.
Where should I start if I've never listened to medical English before?
Start from the root words and suffixes table above, not a list of a thousand words. Then take the free listening level test to pick content at the right level.
You can already handle the written form. What's left is training your ear to get used to how those words sound in real speech, and a dictation listening session with a short medical dialogue is the place to start.
