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.
||tonsillitis, appendicitis (you know these!)
||= abnormal condition
||cyanosis (of blueness, due to cold or low oxygen)
||= to cut out (remove)
||appendectomy, tonsillectomy (you know these too!)

||tracheotomy (to cut into the windpipe,
||= to make a
|colostomy (to make a permanent opening in colon)
||= without, none
||anemia (literally no blood but means few red cells)
||microstomia (abnormally small mouth, see “stomy” in colostomy above?)
||macrostomia (abnormally large mouth)
||megacolon (abnormally large colon = large intestine)
||= to look, observe
||colonoscopy (look into colon)
Just a few more that you will see and hear over and over again.
|mammography (imaging the breasts)
||= the image (X-ray)
Whenever you see these endings, -graphy, -graph, -gram, they relate to recording an image such as an X-ray, CT or MRI scan or a written recording with pen and moving paper. Mammography is the process of recording, i.e. the machine and procedure. Mammogram is the image itself, the X-ray. A recording of heart activity is called an electrocardiogram using an electrocardiograph. A recording of brain activity is an electroencephalogram and the medical procedure and machine is called electroencephalography (whew, what a mouthful!).
||= study, specialize in
||cardiologist, nephrologist (study
the heart, the kidneys)
To see a lung specialist, you would visit a pulmonologist. To see a specialist in nerve and brain disease, make an appointment with a neurologist. If you have a bad eye infection, you may be referred to an ophthalmologist. Your rheumatism acting up? You would want to find a physician specializing in rheumatology.
