Basic Parts of Medical Words
Roots: usually the middle of the word and its central
meaning
2. Prefix: a syllable at the beginning of the word which
usually identifies some subdivision or part of the central
meaning
3. Suffix: comes at the end of the central meaning and refers
to what or who is interacting or what is happening
regarding it.

 Prefix change:
Pericarditis (inflammation of the outer layer of the heart)
Endocartitis (inflammation of the inner lining of the heart)
 Suffix change:
Cardiologist ( a physician specializing in the heart)
Cardiomyopathy (damage to heart muscle layer)
Cardiomegaly (enlargement of the heart)
Pericarditis
Endocarditis
Also: Combining vowels
 Usually is the letter “O” but may be A, E, I, U or Y
 Usually has no meaning of its own but is used to connect the
root and the suffix or two roots and two suffixes
 Example: ELECTR O CARDI O GRAM
GASTR O ENTER ITIS
