If you’re new to allied healthcare, you’ve probably discovered a mountain of important medical words that you’re required to memorize. While it can be daunting, we’ve compiled some excellent tips and tricks to help you on your way. 

Call it your “medical terminology cheat sheet” if you like, but as a healthcare student, you need to thoroughly prepare for your final tests and exams – let this list help up your knowledge, fast. Once you understand how to memorize the most common medical terms, everything else will fall into place. 

Introduction to Basic Medical Terminology

As a future healthcare worker, it’s important to understand basic Greek and Latin roots. While they may seem incredibly complex at first, don’t worry: you already use ancient words every day (like automobile, multimedia, and video) – without even thinking about them! 

Most medical terms consist of three basic components: the root word (the base of the term), prefixes (in front of the root word), and suffixes (at the end of the root word). When combined, you can define a specific medical term.

For example, the word “neuroblastoma” can be broken down this way:

“Neuro” - nerves

+

“Blast” -  immature cell development

+

“Oma” - a cyst or tumor 

How to Study Medical Terminology: Start at the Root

Almost every medical term consists of root words and likely uses prefixes (at the beginning) and/or suffixes (at the end) to modify the end result. Some of the most common roots include: 

Medical Prefixes You Should Know

Prefixes change the meaning of the original word: A prefix (in front of a word) can put an unknown word into perspective. 

For example, if a word begins with “aden-” or “adeno-”, it should always relate to the glands.

The 50 Most Common Medical Suffixes

Studying medical suffixes is great because there are a lot fewer to memorize than prefixes! Medical suffixes typically indicate whether the word is a procedure, disease, condition, or part of speech (e.g. verb, noun, adjective). 

For example, if you hear the word “adenocarcinoma”, the “oma” will inform you that a tumor is present. In this case, a cancerous tumor. 

Some common medical suffixes include:

 When you understand where important medical terms stem from, it’s far easier to read patient charts, communicate with members of staff, and expand your knowledge.  

How Many of These Medical Terms Can You Define? 

Now that you’ve learned some common root words (and the 100 most common medical prefixes and suffixes), you can start to move onto some common language used in healthcare.
