  10. COMBINING VOWELS AND COMBINING FORMS Vowel links the two root words to allow easier pronunciation. o= combining vowel (most common) i=combining vowel

  11. Rules for Forming and Spelling Medical Terms • A combining vowel is used to join root to root as well as root to any suffix beginning with a consonant. Electr + cardi + gram Electr/o/cardi/o/gram = electrical record of the heart

  12. A combining vowel is not used before a suffix that begins with a vowel: Vas + ectomy Vas/ectomy Vas = vessel Ectomy = escision excision of a vessel

  13. If the root ends in a vowel and the suffix begins with the same vowel, drop the final vowel from the root and do not use a combining vowel: Cardi + itis Root(heart) suffix (inflammation) Card/itis inflammation of the heart

  14. Most often, a combining vowel is inserted between two roots even when the second root begins with a vowel. Cardi + esophag + eal Root root suffix Heart esophagus pertaining to Cardi/o/esophageal (pertaining to the heart and esophagus)

  15. Occasionally, when a prefix ends in a vowel and the root begins with a vowel, the final vowel is dropped from the prefix. Para + enter + al Prefix root suffix Alongside of intestine pertaining to Par/enter/al = parenteral Pertaining to alongside of the intestine

  16. Defining Medical Terms Through Word Structure Analysis Interpret the suffix first, then prefix, then the roots. Peri / card / itis Prefix root suffix Around heart inflammation Pericarditis – inflammation around the heart.

  19. Pronunciation C (before a,o,u) = k ex. Colon, cavity, cure C (before e,i) = s ex. Cephalic, cirrhosis Ch = k ex. Cholesterol G (before a,o,u) = g ex. Gallstone, gonad, gurney G (before e,i) = j ex. Generic, giant Ph=f ex. Phase Pn=n ex. Pneumonia Ps=s ex. Psychology Pt=tptosis

  20. Rh=r ex. Rhythm Rrh=r ex. Hemorrhoid X=z (as first letter) ex. xerosis
