What is Medical Terminology?
Medical terminology is a specialized language used by healthcare providers to describe the human body, medical conditions, procedures, and treatments accurately and efficiently. It allows for clear communication among professionals and reduces errors.
Importance of Learning Medical Terminology
- Facilitates accurate documentation and record-keeping
- Enhances communication with patients and colleagues
- Aids in understanding medical reports and instructions
- Supports effective learning in health sciences

Core Components of Medical Terminology
Medical terms are constructed from basic building blocks that include roots, prefixes, suffixes, and combining vowels. Mastering these components allows for the creation and understanding of complex terms.
Roots
The root is the core part of the word that contains the primary meaning. It often indicates a body part, condition, or concept.
Examples:
- Cardi (heart)
- Gastr (stomach)
- Neur (nerve)
- Hemat (blood)
Prefixes
Prefixes are added to the beginning of a root to modify its meaning, often indicating location, number, time, or status.
Common prefixes:
- a- / an-: without, not (e.g., anemia – without blood)
- brady-: slow (e.g., bradycardia – slow heart rate)
- tachy-: fast (e.g., tachypnea – rapid breathing)
- hyper-: excessive, above normal (e.g., hypertension – high blood pressure)
- hypo-: deficient, below normal (e.g., hypoglycemia – low blood sugar)
Suffixes
Suffixes are added at the end of a root to provide additional meaning, such as condition, procedure, or disease.
Common suffixes:
- -itis: inflammation (e.g., appendicitis)
- -ectomy: surgical removal (e.g., appendectomy)
- -ology: study of (e.g., cardiology)
- -osis: abnormal condition (e.g., leukocytosis)
- -pathy: disease or disorder (e.g., neuropathy)
Combining Vowels
The vowel "o" is most commonly used to connect roots and suffixes or roots and prefixes, making terms easier to pronounce.

How to Break Down Medical Terms
Understanding how to analyze and interpret complex medical words is vital. Follow these steps:
1. Identify the suffix: Usually at the end of the word, indicating the condition or procedure.
2. Identify the prefix: At the beginning, providing additional context.
3. Find the root(s): The core part conveying the main meaning.
4. Combine components: Understand how they relate to form the complete term.
Example:
- Term: Hypoglycemia
- Prefix: hypo- (below normal)
- Root: glyc (sugar)
- Suffix: -emia (blood condition)
- Meaning: Low blood sugar
