Medical terminology is a vast and complex field, with a multitude of words and phrases used to describe various medical conditions, procedures, and treatments. One of the key components of medical terminology is combining forms, which are used to create new words by combining different roots, prefixes, and suffixes. In this article, we will explore the world of combining forms in medical terminology, including their definition, types, and examples, as well as their importance in the medical field.
What are Combining Forms?

Combining forms are the building blocks of medical terminology, used to create new words by combining different roots, prefixes, and suffixes. They are also known as combining vowels or combining forms with a vowel. Combining forms are used to link roots to other elements, such as prefixes and suffixes, to create new words. For example, the combining form of the root “cardio-” (meaning heart) is “cardi-”, which is used to create words such as “cardiology” (the study of the heart) and “cardiac” (relating to the heart).
Types of Combining Forms
There are several types of combining forms used in medical terminology, including:
- Root combining forms: These are the most common type of combining form, used to link roots to other elements. Examples include “cardi-” (heart), “neur-” (nerve), and “gastr-” (stomach).
- Prefix combining forms: These are used to link prefixes to roots. Examples include “anti-” (against), “hyper-” (excessive), and “hypo-” (deficient).
- Suffix combining forms: These are used to link suffixes to roots. Examples include “-itis” (inflammation), “-osis” (condition), and “-ectomy” (surgical removal).
| Root | Combining Form | Example Word |
|---|---|---|
| cardio- | cardi- | cardiology |
| neur- | neur- | neurology |
| gastr- | gastr- | gastroenterology |

Importance of Combining Forms in Medical Terminology

Combining forms play a crucial role in medical terminology, as they enable healthcare professionals to create new words and phrases to describe complex medical concepts and conditions. By using combining forms, healthcare professionals can:
- Improve communication: Combining forms help healthcare professionals to communicate complex medical information clearly and accurately.
- Enhance patient care: By using combining forms to describe medical conditions and treatments, healthcare professionals can provide more effective patient care and improve health outcomes.
- Facilitate medical research: Combining forms are used in medical research to create new words and phrases to describe emerging medical concepts and conditions.
