Basics
Before we can start in with some new and interesting medical
terms, you need to learn a few fundamentals of how medical
terminology is constructed as a language.
There are three basic parts to medical terms: a word root (usually
the middle of the word and its central meaning), a prefix (comes
at the beginning and usually identifies some subdivision or part of
the central meaning), and a suffix (comes at the end and modifies
the central meaning as to what or who is interacting with it or
what is happening to it). An example may make better sense.
Word root
therm = heat
hypothermia (less heat), thermometer (measuring heat)
Let’s look at a real medical term and take it apart.
Myocarditis
(prefix) (root) (suffix)
myo = muscle card = heart
itis = inflammation
Don’t get blown away by that big, intimidating word! We haven’t
introduced word roots yet. I just wanted to demonstrate the major parts
of a medical term. Let’s see how prefix and suffix changes can alter the
meaning of a term without changing its central meaning by keeping the
root the same.
Prefix change:
myocarditis = muscle layer of heart inflamed
pericarditis = outer layer of heart inflamed
Endocarditis = inner layer of heart inflamed
Suffix change:
cardiologist = a physician specializing in the heart
cardiomyopathy = damage to heart muscle layer
cardiomegaly
= enlargement of the heart
Again, we haven’t introduced heart terms yet. These
basics are just to introduce the parts of medical terms
and demonstrate how moving the parts around modifies
the central meaning without changing the “root”
(cardio).
Useful prefixes and suffixes
Following, in no particular order, are frequently used word
beginnings (prefixes) and word endings (suffixes) used to make up
many medical terms. You don’t need to memorize whether an
item is a prefix or suffix, or even if it is a word root, just what it
means! I know this is all “Greek” to you (and some of it really is!),
but there will be so much reinforcement as we go along that you
can’t help but remember meanings. Be patient with yourself.
