Latin Medical Terminologies

Latin Medical Terminologiess (LMTs)

Student Guide Overview

In medical sciences, Latin and Greek terminology form the foundation of most scientific and clinical vocabulary. Understanding how medical words are constructed helps students decode complex terms, recognize patterns, and build strong communication skills across all medical specialties.
All Latin medical terms can be analyzed under four main components:

1. Prefixes: A prefix is a word part placed before the root to modify or refine its meaning often describing location, number, time, or status.

Examples:

sub- = below  (subcutaneous = under the skin)

hyper- = (excessive = hypertension/ high blood pressure)

brady- = (slow = bradycardia/ slow heart rate)

peri- = (around = pericardium/ membrane around the heart)

249 prefixes were listed

2. Roots: The root is the core element of a medical term. It indicates the main structure, organ, or concept being described.

Examples:

cardi = (heart)

nephr = (kidney = nephrology (study of the kidney)

oste = (bone/ osteocyte (bone cell)

derm  = (skin/ dermatitis (inflammation of the skin)

 1070 roots were listed

3. Suffixes: A suffix is placed at the end of a word root to describe condition, procedure, or disease. It transforms the root into a complete medical term.

Examples:

-itis = (inflammation / arthritis (inflammation of joints)

-ectomy = (surgical removal / appendectomy (removal of appendix)

-ology = (study of/ neurology (study of the nervous system)

-emia = (blood condition/ anemia (lack of red blood cells)

 1017 suffixes were listed

4. Multicomponent Terminology: Most advanced medical terms are multicomponent, meaning they combine prefix(es), root(s), and suffix(es) to form precise, descriptive words that express full medical meanings.

Examples:

Spondyloarthropathy = spondylo- = vertebra, arthro- = joint, -pathy = disease). Disease affecting vertebral joints 

Electrocardiogram = (electr- (electricity) + cardi- (heart) + -gram (record) Record of the electrical activity of the heart

Gastroenterology = (gastr- (stomach) + enter- (intestine) + -ology (study) Study of the stomach and intestines

Hypoglycemia = (hypo- (low) + glyc- (sugar) + -emia (blood condition) Low blood sugar condition

Otorhinolaryngology = (oto- (ear) + rhino- (nose) + laryngo- (throat) + -logy (study) Study of the ear, nose, and throat

 204 multicompound were listed

📘 Study Tip for Students

• Learn prefixes, roots, and suffixes separately first.

• Then, practice combining them to form complex medical terms.

• We create flashcards lists to help memorize patterns.

• Use multi-component examples to build confidence in interpreting unfamiliar terms.
