Medical Terminology

It is nearly impossible for even the most experienced health professional to be familiar with every medical term. However, knowledge of prefixes, suffixes, and root words is essential. It is vital that every health professional be familiar with the commonly used medical terminology.

Word Parts / Building Blocks Most medical terms are formed by a combination of basic word parts. An understanding of how these parts work together makes interpreting medical language easier.

Root Words usually indicate the part of the body involved All medical terms must have one or more root words

Prefixes usually indicate location, time, or number - come at the beginning of the word Not all medical terms have prefixes

Suffixes usually indicate the procedure, disease, or condition - come after the root word The suffix, when connected to the root word will create a noun, adjective, or verb. All medical terms have a suffix.

Combining Vowel or Combining Form usually "O" attached to root word used to make medical terms easier to pronounce is NOT used when suffix begins with a vowel IS used when suffix begins with a consonant

Decoding Medical Terms Start with the suffix and define the suffix. Go to the prefix and define the prefix. Then, go to the middle of the word; define the word root, combining form, or both if both exist in the same word. Combine the definitions to decode the complete medical term or phrase.
