Medical Terminology;Medical Terminology ; The Key: Learning medical terminology is much easier once you understand how word parts work together to form medical terms. It’s just like an Architect trying to make a beautiful design for building. The Four Types of Word Parts Four types of word parts may be used to create medical terms. ;A word root contains the basic meaning of the term. This word part usually, but not always, indicates the involved body part. For example, the word root meaning stomach is gastr. A combining form is a word root with a vowel at the end so that a suffix beginning with a consonant can be added. When a combining form appears alone, it is shown with a slash (/) between the word root and the combining vowel. For example, the combining form meaning stomach is gastr/o. ;WORD PART GUIDELINES;1.
