Medical Terminology: Latin and Greek Roots

Now for some of the fun terms! These may be out of alphabetical order, so my apologies there. This is just a short selection of some common and interesting terms; more will come soon. These terms will also be re-organized when I finish the next two posts.

——————————————

pachy-: A thickening of the skin - pachyderma is a thickening of the skin, and pachydermata is an obsolete class of mammals with thick skin…elephants and their close kin are still often referred to as “pachyderms” in non-scientific literature.

path(o)-/-pathy: Disease, pertaining to a disease or disorder (ex: pathologist, neuropathy)

pyro-/pur-: fever (from pyro - fire, but you probably already guessed that!)

-mania: "Mental derangement characterized by excitement or delusion", craze, insanity, passion, spirit

dys-: abnormal, wrong, painful, difficult

phos-: Pertaining to light and its chemical properties (when not used in terms of phosphorescence, this is a nearly completely archaic root)

ec-/ex(o)-: Out, outside of, away from

myco-: Pertaining to fungus (don’t confuse with myo - pertaining to muscle, or myx(o)- pertaining to mucus!)

-pexia: Fixation upon

sangui-/sanguine: Pertaining to blood
