01| Medical Word Elements

（1）Word root

（2）Combining form

（3）Suffix

（4）Prefix

Word Roots

1）the foundation of a medical term and contains its primary meaning

2）Most word roots are derived from Greek or Latin language

3）Greek roots are used to build words that describe a disease, condition, treatment, or diagnosis.

4）Latin roots are used to build words that describe anatomical structures

Examples of Word Roots

Combining Forms

1）created when a word root is combined with a vowel

2）known as a combining vowel, is usually an o, but sometimes it is an i. The combining vowel has no meaning of its own, but enables two word elements to be connected

Examples of Combining Forms

Suffixes

1）a word element placed at the end of a word that changes the meaning of the word

2）usually describes a pathology (disease or abnormality), symptom, surgical or diagnostic procedure, or part of speech

Examples of Suffixes

Prefixes

1）a word element attached to the beginning of a word or word root

2）The prefix usually indicates a number, time, position, direction, or negation

3）Many of the same prefixes used in medical terminology are also used in the English language

Examples of Prefixes

02| Basic Guidelines

Defining and building medical words are crucial skills in mastering medical terminology. Following the basic guidelines for each will help you develop these skills.

03| Defining Medical Words

Three basic steps for defining medical words using gastroenteritis as an example.

1. Define the suffix, or last part of the word. In this case, the suffix -itis, which means inflammation.

2. Define the first part of the word (which may be a word root, combining form, or prefix). In this case, the combining form gastr/o means stomach.

3. Define the middle parts of the word. In this case, the word root enter means intestine.

When you analyze gastroenteritis following the three previous rules, the meaning is: inflammation (of ) stomach (and) intestine.
