1 Identifying Word Parts in Medical Terms
Word Parts
Medical terms are built from word parts. Those word parts are prefix, word root, suffix, and combining form vowel. When a word root is combined with a combining form vowel the word part is referred to as a combining form.

Language Rules
Language rules are a good place to start when building a medical terminology foundation. Many medical terms are built from word parts and can be translated literally. At first, literal translations sound awkward. Once you build a medical vocabulary and become proficient at using it, the awkwardness will slip away. For example, suffixes will no longer be stated and will be assumed. The definition of intravenous then becomes within the vein.
Since you are at the beginning of building your medical terminology foundation stay literal when applicable. It should be noted that as with all language rules there are always exceptions and we refer to those as rebels. So let’s begin by analyzing the language rules for medical terminology.
