Defining medical terms:
- A prefix is placed at the beginning of a word
- Example: Bi/articulate-double joint
- There are three steps to defining medical terms:
- First define the sufffix.
- Then, define the first part of the word which can be a word root, combining form, or prefix.
- Lastly define the middle portion of the word which can be a word root or combining form.
- A word root links a suffix that starts with a vowel
- Example: cyt/o/logy
- A combining form links a suffix that begins with a consonant
- Example: dermat/o/itis
