If you come across a word likecryoglobulinemiaand think,It’s Greek to me, there’s good reason for that. It is Greek. And Latin. Most medical terms — over 90% — originate in Greek and Latin. But don’t let that intimidate you when it comes to medical terminology.
More than 60% of our everyday words are borrowed from Greek and Latin, which means you have a familiarity with medical terminology that you might not realize. It’s not a big jump, for example, to go fromacrobattoacromaniaoracroanesthesia.
Among our tips and strategies for learning medical terminology, we’re going to show you how to put your familiarity to work for you. But first, let’s answer a few questions so we can establish who should study medical terminology and why.
What is medical terminology?
Medical terminology is the language of healthcare. It’s the means for healthcare professionals to confer on the intricacies of the human body, both in states of health and states of injury or disease. As such, medical terminology comprises the lexicon of labels for all known anatomical features, physiological processes, and medical interventions.
Why is it important to understand medical terminology?
Understanding medical terminology opens a door to understanding both medicine and the healthcare community. The more you need to understand either of these, the more important your understanding of medical terminology becomes.
Who should learn medical terminology?
If you’re seeking a career with daily responsibilities that will require you to know an anatomical feature from a physiological process from a medical intervention, then you’ll need to gain fluency in medical language to perform your job.
Equally important, you’ll need to understand medical terminology to succeed in your career training program, as well as your prospective workplace. This is true if you’re choosing a career on the clinical side of healthcare as a medical sonographer, radiation therapist, or magnetic resonance imaging technologist. It’s also true if you’re pursuing a career on the business side of healthcare as a medical scribe, medical transcriptionist, medical biller, or medical coder.
Is medical terminology hard to learn?
A word likeosteochondrodysplasiais an eyeful — and there are thousands of terms like it — but don’t let appearances fool you. Learning medical terminology isn’t as difficult as you’d think. Not if you approach it right, with the right strategies and right resources.
Build your medical vocabulary brick by brick
When it comes to medical terminology, think LEGO. A LEGO brick is just a LEGO brick, but when you snap these pieces of plastic together, you get something upscale.
Similarly, word parts — like mini bricks — make up most medical terms. Once you start to learn the word parts, you no longer see an unknowable 21-letter word. When, for example, you look atosteochondrodysplasia, you see:
So osteochondrodysplasia becomes recognizable. You might not know the full extent of the definition, but you piece together that the term refers to a developmental abnormality that affects bone and cartilage.
And just as a LEGO brick can be used in different constructions, you’ll see a same word part in numerous medical terms. In fact, now that you learned four word parts, you have insight on an exponential list of medical terms.
We’ll look at more examples of word parts and show you how familiarity goes a long way in building your medical terminology vocabulary, but first let’s look at the different types of word parts.
3 component types
The construction of most medical terms follows the common structure of a prefix, medical root, and suffix.
Medical Prefixes: When included, the prefix appears at the beginning of a medical term and usually indicates location, direction, time, quality, or quantity.
Medical Suffixes: The suffix is tacked onto the end of a term and typically indicates a procedure, function, test, condition, or pathology. The suffix may also identify if the term is a noun, adjective, or verb.
Medical Root Words: The root word is the base part of the medical term and conveys its primary meaning, which is often a body part or body system. Most medical terms contain one or more root words.
Deconstructing medical terms to their components
Mentally dividing a medical term into its word parts will help you to figure out the meaning of the unfamiliar term. But before you can deconstruct medical terms, you need to know a few things about how they’re constructed.
A medical term can consist of almost any combination of word parts:
Prefix, root word, suffix
Root word, suffix
Root word, root word, suffix
Root word, root word, root word
Prefix, suffix
Combining vowel
Medical terms get awkward to pronounce without a device for linking word parts, and so the combining vowel system was developed.
When two medical root words are connected, a combining vowel is added to the end of the first root word. A combining vowel is used with the second root word if the subsequent word part begins with a consonant. The letterois the most commonly used combining vowel.
By way of example,gastris the root word for stomach. When linked with the suffix -logy, meaning study or medical field, anois added, forming the word gastrology.
But if the word part followinggastrbegins with a vowel, then the combining vowel is unnecessary, as seen in the example term gastritis, which means inflammation of the stomach lining.
In the medical term deconstructed below, we see an example of two combining vowel practices — anolinking root words, and the omission of the combiningowhen the suffix begins with a vowel.
But what about when a root word ends in a vowel? The combiningois again omitted, as seen in the medical terminology example enterocentesis, which refers to a surgical puncture of the intestines. Enterocentesis also illustrates that not all root words refer to human anatomy.
Lastly, if you’re wondering why we didn’t break down a medical term with a prefix to illustrate how the prefix links to a root word, it’s because the combining vowel only applies to root words and suffixes.
Whether a prefix ends in a vowel or a consonant is of no consequence to the formation of the medical term, as you can see in these two examples.
While you’re probably familiar with the words hypoglycemia (low blood sugar) and hyperthermia (elevated body temperature), you can now see where their definitions originate.
How to learn medical terminology
Understanding the structure of medical terms allows you to see the word parts and leverage an ever-increasing familiarity with them. This is an expedient way to get a handle on medical language.
Consider the wordhemorrhage, for instance. You know the meaning of the term, but you probably never noticed the word parts. Can you see the structure now? If not, look for ano. Not all medical terms have a combiningo, but when they do, it’s an obvious demarcation of structure.
Theoin hemorrhage divides the term in two: hem + o + rrhage. You may recognizehemor guess that it means blood, and you’d be correct.-rrhageis likely new to you. It meansburst, as in a dam breaking, and conveys excessive bleeding or fluid loss resulting from a damaged blood vessel.
Making a note of the structure in this one term gives you a head start on words like rhinorrhage, splenorrhage, otorrhage, hepatorrage. And once you learn the root words in these four terms — nose, spleen, ear, and liver respectively — you’re able to expand your medical vocabulary in four directions.
Learn from familiar terms
Here are a few tips that will take you far:
Learn from the words you know. If, for example, you know that a tonsillectomy is the surgical removal of the tonsils, then you know what the suffix -ectomy means. Make a flashcard.
When you learn a new medical term, make flashcards of its word parts.
Quiz yourself often.
Organize your study of medical root words by body system
When learning new information, context is like a corkboard in your brain, giving the information a place to stick. For this reason, you’ll find lessons structured categorically when you takeanatomy and medical terminology courses. Understanding and retaining information is easier with a categorical approach.
While reviewing a sampling of root words below, remember: As with a prefix and suffix, a root word is a part of the medical term and is not a word in itself. A suffix, with few exceptions, will be added to the root word to complete it.

Earlier we told you that a medical term could consist of almost any combination of word parts — including root words only. This is a rare occurrence and, as we’ll show you, only technically true.
Sternocleidomastoid. In this example, three root words are combined to form sternocleidomastoid, which refers to a muscle on each side of your neck that starts at the top of the sternum and the clavicle, then reaches up to insert behind your ear on the mastoid process of the temporal bone. It’s an unusual medical term, in that it doesn’t have a suffix. As you’ll soon see, though, -oid is a suffix meaningto resembleorsimilar to. Because it’s built into the root wordmastoid, these three root words together are complete.
Of course, root words can represent more than body parts and body systems.
Medical root words: Colors

---|---|
chlor | green |
cyan | blue |
erythr | red |
alb, leuk | white |
melan | black |

Common prefixes
Before peeking below, test your thought process. You’re familiar with the worddehydrateand with the wordhydrate, so what do you think the de- prefix means?
Remember to analyze new terms. Break down the word parts, think it through, and keep adding to your stack of medical terminology flashcards.
Medical prefixes: Position, location, direction
PREFIX | MEANING |
---|---|
ab- | away from |
ad- | toward |
ante- | before, forward |
anter-, anteri- | front, forward |
ap-, apo- | away from, detached |
centre- | center |
circum-, peri- | around |
con- | together |
dia- | through, apart |
dis- | apart, away from |
e- | out from |
ec-, ecto-, ex-, extra- | out of, outside |
end-, endo- | within, inside |
epi- | upon |
inter- | between |
intra | within |
meta- | after, beyond |
post- | behind |
postero- | back or posterior to |
sub- | under |
trans- | across |
Always note context
As you see in the above table, post means behind. This prefix, though, must be read contextually to parse the correct meaning of the medical term in question. For example, postcordial meansbehindthe heart, whereas postvaccinal meansaftervaccination. In one instance post- indicates a location and in the other instance, post- indicates time.
While dual meanings attributed to word parts aren’t overly common, they’re not uncommon either. Consider anteversion, the tipping forward of an organ, versus antepartum, before childbirth.
In another sense, you can think of post- and ante- as each have one definition:
Post-: after, in space or time
Ante-: before, in space or time
The point to remember is, when deconstructing medical terms, use common sense, equal parts logic and familiarity.
Medical prefixes: Time or speed
PREFIX | MEANING |
---|---|
ante- | before |
brady- | slow |
chron- | time, long time |
post- | after |
pro-, pre-, ante- | before |
re- | again |
retro- | back/backward |
tachy- | fast |
Medical prefixes: Number or quantity

Pay attention to spelling
Ilium and ileum. A one-letter substitution and you have a different word, which is why you'll need to examine provider documentation as it pertains to your professional responsibilities.
Spelling matters when it comes to reading a patient's diagnosis, test results, medicine prescriptions, and treatments. Incorrectly interpreting patient information can adversely affect patient care.
Tip: In addition to taking caution with look-alike words and medical abbreviations, familiarize yourself with the plural form of common suffixes you'll encounter.
Getting straight on plural form
The plural form of most medical terms departs from the standardsores. In some cases, you'll find leniency. You could, for instance, say sacromas instead of sarcomata, but you need to know plural form well enough to recognize what you're reading.
How a medical term is made plural depends on the last two letters of its singular suffix.
Pluralizing medical terminology suffixes
Singular | Plural | Example |
---|---|---|
-a | -ae | bursa, bursae |
-anx, -inx, -ynx | -nges | phalanx, phalanges |
-en | -ina | foramen, foramina |
-ex, -ix, -yx | -ices | cervix, cervices |
-is | -es | diagnosis, diagnoses |
-it is | -itides | meningitis, meningities |
-ma | -mata | sarcoma, sarcomata |
-on | -a | ganglion, ganglia |
-um | -a | diverticulum, diverticula |
-us | -es, -i | plexus, plexuses and embolus, emboli |
-x | -ces | thorax, thoraces |
Take a medical terminology course
If your sights are set on the healthcare profession, specifically medical coding, consider prioritizing anonline medical terminology course. Though learning medical terminology may be easier than you thought, there’s still a lot to learn.
In addition to anatomical terms, conditions, diseases, injuries, surgical procedures, and medical treatments — all of which number in the thousands — you also need to navigate a myriad of drugs, equipment, and supplies. And not all body parts and medical words are composed of identifiable components.
Consider the integumentary system. The skin is the body's largest organ and is studied as an anatomical system, just like the musculoskeletal system, urinary system, nervous system, endocrine system, etc. But the “skin” system gets its name fromintegument, a Latin word that means to cover. Integument is just one example of a medical word that is not intuitive, as it cannot be broken down into recognizable parts.
You’ll also encounter medical terminology referred to by multiple terms, as well as eponyms (words derived from someone’s name) and acronyms, ands words derived from Latin and French.
For this reason, AAPC requires students training for a career in medical coding to take a medical terminology class. The importance of a reliable and expansive medical vocabulary, in addition to knowledge ofhuman anatomy, can’t be understated.
Get a medical dictionary
Albert Einstein is credited with saying, "Never memorize what you can look up in books." Smart man. You will undoubtably commit much of your career training to memory, but the human brain has limits.
So start building a library, and choose a good medical dictionary for your first purchase. You'll need a comprehensive resource —Dorland's Illustrated Medical DictionaryorStedman's Medical Dictionary for the Health Professions and Nursing. If you’re tempted to cut costs and go with free web content, you won't have access to the information you need. Consider buying used instead.
Theis designed for coding and billing students. You can reference anatomical illustrations and industry acronyms, as well as an extensive glossary of coding, billing, and medical terms. It's worth taking alook insideto see if this book meets your needs.
But don't forget, you'll also find helpful info in yourCPT® code books. This includes illustrations, diagrams, and medical abbreviations. For those with Codify subscriptions, you can addDorland's Illustrated Medical Dictionary, which gives you full content and makes deciphering chart note terms easy.
Stoke your motivation
Why are you studying medical terminology? For many of you, the answer to that question is a rewarding career inmedical coding and billing. Our final tip to acing medical terminology, then, is to keep thatcareer goalfront and center. Motivation will fuel your studies, helping you to go the distance and to enjoy the journey.
