Suffixes usually but not always indicate the procedure, condition, disorder or disease. A suffix comes at the end of the word.

-

Prefixes come at the beginning of a word. They usually indicate location, time, number or status.

- Combining Vowels - To make medical terms easier to pronounce, a combining vowel may be needed between a word root and another word root or a suffix. - The letter O is the most commonly used combining vowel. - When a word root is shown with a slash and a combining vowel it is called a combining form, i.e. cardi/o, hemat/o
