Why Learn Medical Word Parts?

Okay, so why should you even bother learning all these weird word parts? Well, think of it this way: it's like learning the alphabet before you can read. Medical terms are often constructed from prefixes, suffixes, and root words. By understanding these components, you can break down complex terms into manageable pieces and decipher their meaning.

  • Career Advancement: A valuable skill for anyone in the healthcare field.

The Building Blocks: Prefixes, Suffixes, and Root Words

Before we jump into the glossary, let's quickly review the basic types of medical word parts. Imagine you're building a house. The root is the foundation, the prefix is like adding a front porch, and the suffix is like adding a chimney. Each part contributes to the overall structure and meaning.

  • Root Words: The core meaning of the term (e.g., cardi means heart).
  • Prefixes: Added to the beginning of a word to modify its meaning (e.g., tachy- means fast).
  • Suffixes: Added to the end of a word to modify its meaning (e.g., -itis means inflammation).
