Root
Prefix
Suffix
Combining form

6. Word Roots (WR) Usually derived form Greek or Latin
Frequently indicates a body part
Most medical terms have one or more word roots
Gives basic meaning of term

7. In medical terminology roots usually indicate a body part:
pulmon/o
dent/o

9. 2. the prefix is Example: pretest
a word part added before a root to modify its meaning
many medical terms do not have a prefix
Usually indicates a number, time, position, direction, or color
Example: pretest

10. Prefix examples:
“number” prefixes
uni- (uni/lateral)
bi- (bi/lateral)
tri- (tri/)
“time” prefixes
pre- (pre/test)
post- (post/test)

11. “position” prefixes
sub- (sub/costal)
trans- (trans/atlantic)
hypo- (hypo/dermic)
“negation” prefixes
a- (a/moral)
an- (an/aerobic)

12. Example: root--teach to teacher
3. the suffix is
a word part added to end of root to modify its meaning
most medical terms have a suffix Word Ending
Suffix usually indicates a procedure, condition, or disease
Example: root--teach to
teacher

13. In medical terminology, a suffix often times indicates:
a procedure ( -ectomy = surgical removal of)
append/ectomy
a condition ( -osis = abnormal condition of)
dermat/osis
a disease ( -itis = inflammation of)
tonsill/itis

14. 4.Combining Forms (CF)
usually an “o” that is used between word parts
eases pronunciation
A root word plus a vowel is referred to as a “combining form”.

15. Combining Forms Examples
Cardi/ + o = cardi/o heart
gastr/ + o = gastr/o stomach
hepat/ + o = hepat/o liver
nephr/ + o = nephr/o kidney
oste/ + o = oste/o bone
