CCMA Medical Terminology: Prefixes, Roots, and Suffixes
CCMA medical terminology memory card: word-building formula, high-yield surgical and pathology suffixes, prefixes, organ roots, and decode examples.
By MedCertPrep Team · Updated August 4, 2026
This guide is a high-yield memory card for NHA CCMA medical terminology: prefixes, combining forms (roots), and suffixes used to decode chart language, orders, and exam stems. It is written for candidates who want a repeatable word-building method, not a giant glossary dump. Practice recognition in Foundational Knowledge. For drug-name suffixes (a different skill), use CCMA drug classifications.
Medical terminology is listed in the NHA CCMA Test Plan under Foundational Knowledge (word building, common abbreviations, positional terms, and lay vs medical wording). This card is a study aid aligned to those themes.
How do you decode a medical term on the CCMA?
Use this formula:
Prefix + root/combining form + suffix = meaning
Work from the suffix first (what is happening), then the root (which body part), then the prefix (where/how much/when). Example: hepatomegaly = liver + enlargement.
Pro Tip: If two options look similar, check the suffix pair carefully. -ectomy, -otomy, and -ostomy are classic near-miss distractors.
What surgical and procedure suffixes are highest yield?
| Suffix | Meaning | Example | Decode |
|---|---|---|---|
| -ectomy | Excision / removal | appendectomy | Removal of the appendix |
| -otomy | Incision / cutting into | phlebotomy | Incision into a vein (venipuncture context) |
| -ostomy | Creating an opening | colostomy | Opening from the colon to the body surface |
| -plasty | Surgical repair / reshaping | rhinoplasty | Surgical repair of the nose |
| -centesis | Surgical puncture to remove fluid | amniocentesis | Puncture of the amniotic sac |
| -tripsy | Crushing | lithotripsy | Crushing of a stone |
What diagnostic suffixes should I separate carefully?
| Suffix | Meaning | Example | Decode |
|---|---|---|---|
| -graphy | Process of recording | electrocardiography | Process of recording the heart's electrical activity |
| -gram | The record / image produced | electrocardiogram | The ECG tracing itself |
| -scopy | Visual examination process | endoscopy | Looking inside with a scope |
| -scope | Instrument for viewing | stethoscope | Instrument used to listen/examine |
Remember: -graphy / -scopy are processes. -gram is the record. -scope is the tool.
What pathology and symptom suffixes appear most?
| Suffix | Meaning | Example |
|---|---|---|
| -itis | Inflammation | dermatitis |
| -algia / -dynia | Pain | neuralgia |
| -omegaly | Enlargement | hepatomegaly |
| -oma | Tumor / mass | melanoma |
| -pathy | Disease | nephropathy |
| -rrhage / -rrhagia | Bursting forth / excessive flow | hemorrhage |
| -rrhea | Flow / discharge | diarrhea |
| -sclerosis | Hardening | arteriosclerosis |
| -penia | Deficiency / decrease | leukopenia |
What prefixes change location, amount, or speed?
Position and direction
| Prefix | Meaning | Example |
|---|---|---|
| epi- | Above / upon | epidermis |
| hypo- / sub- | Below / under / deficient (context matters) | subcutaneous, hypodermic |
| inter- | Between | intercostal |
| intra- / endo- | Within / inside | intravenous, endoscope |
| extra- / exo- | Outside | extracellular |
| peri- | Around | pericardium |
| trans- | Across / through | transdermal |
Quantity, degree, and negation
| Prefix | Meaning | Example |
|---|---|---|
| hyper- | Excessive / high | hypertension |
| hypo- | Low / deficient | hypoglycemia |
| tachy- | Fast | tachycardia |
| brady- | Slow | bradypnea |
| poly- / multi- | Many / much | polyuria |
| oligo- | Few / scanty | oliguria |
| a- / an- | Without / not | apnea, anemia |
Which organ combining forms should I memorize first?
| Combining form | Meaning | Quick example |
|---|---|---|
| cardi/o | Heart | cardiomegaly |
| hepat/o | Liver | hepatitis |
| nephr/o or ren/o | Kidney | nephrectomy |
| dermat/o or derm/o | Skin | dermatologist |
| oste/o | Bone | osteoarthritis |
| my/o | Muscle | myocardial |
| phleb/o or ven/o | Vein | phlebitis |
| pneumon/o or pulmon/o | Lung | pneumonia |
| gastr/o | Stomach | gastritis |
| enter/o | Intestine | gastroenteritis |
| thorac/o | Chest | thoracentesis |
| lingu/o or gloss/o | Tongue | sublingual |
How do I break terms the way exam stems expect?
- Gastroenteritis = gastr/o (stomach) + enter/o (intestine) + -itis (inflammation) �?inflammation of stomach and intestine
- Sublingual = sub- (under) + lingu/o (tongue) + -al (pertaining to) �?under the tongue (common route teaching point)
- Thoracentesis (also written thoracocentesis) = thorac/o (chest) + -centesis (puncture to remove fluid) �?chest puncture for fluid removal
Practice building and decoding in Foundational Knowledge.
What abbreviation habits also matter?
Terminology stems often sit next to abbreviation safety. Know common chart abbreviations used in ambulatory care, and treat The Joint Commission Do Not Use list items as high-risk (for example ambiguous dose shorthand). When unsure, write terms out rather than inventing unsafe abbreviations. Confirm current safety lists through clinic policy and official references.

Frequently Asked Questions
What is the fastest way to learn medical terminology for the CCMA?
Learn high-frequency suffixes and prefixes first, then attach organ roots. Decode 10 mixed terms daily instead of rereading long alphabet lists.
What is the difference between -ectomy, -otomy, and -ostomy?
-ectomy removes. -otomy cuts into. -ostomy creates an opening. Mixing these three is one of the most common terminology misses.
What is the difference between -gram and -graphy?
-graphy is the process of recording. -gram is the record produced. Electrocardiography is the process; electrocardiogram is the tracing.
Do hyper- and hypo- only apply to blood pressure?
No. They mark high vs low or excessive vs deficient across many terms: hypertension, hypoglycemia, hyperthermia, and similar pairs.
Should I memorize every combining form in a textbook appendix?
No. Start with the organ roots in this card, then add only the roots that keep appearing in your miss log.
How is medical terminology different from drug classification suffixes?
Medical terminology builds clinical words (hepatitis, phlebotomy). Drug classification suffixes identify medication families (-pril, -olol). Study both, but keep them on separate cards: this guide vs drug classifications.
Start the decode drill today
- Cover the surgical suffix table and write meanings from memory.
- Add hyper-/hypo- and tachy-/brady- pairs.
- Decode five mixed terms without looking, then check.
- Open Foundational Knowledge for recognition stems.
- Keep the week moving with the CCMA study plan.
Suffix first. Root second. Prefix last. That order turns unfamiliar words into points.
