It’s all Greek (or Latin) to me!
Learning and understanding the roots of most words in the
field of Health and Medicine can help you to understand
what is being discussed ORIGIN OF MEDICAL TERMS
Hippocrates was a Hippocrates was a Greek physician and
is known as the is known as the “father of medicine.”
75% of medical terms are based on terms are based
on either Greek or Latin words.

Two basic rules for building medicalwords:
Rule 1: A stem word (the main meaning) is used before a suffix that begins with a vowel
Scler/ + Osis = Sclerosis =
(hardening) (abnormal condition)
Sclerosis
Rule 2: A combining vowel – usually an o (Sometimes ‘a,’ ‘e,’ ‘i,’ ‘u,’ or ‘y.’is used to link a stem word to a suffix that begins with a consonant and to link a stem word to another stem word to form a compound word.
Colon + o + scope = colonoscope
(colon) (instrument to view)
Colon + o + scopy = the procedure
Colonoscopy

Stem (or root) words – main stem (part) of word and can appear at the beginning (prefix) in the middle or at the end of the word (suffix)

Compound Words
A combining vowel is used to link a stem word to another stem word to another one for a compound word such as:
Gastr + o + enter = itis = gastroenteritis
(stomach) (intestine) (inflammation)Oste + o + arthr + itis = osteoarthritis
(bone) (joint) (inflammation)
