Combining Vowel A vowel that links two word parts together Usually an ‘o’ Has no meaning of it’s own
Combining Form – root word plus a combining vowel
Examples:Hemat/o – Cardi/o – Gastr/o – Oste/o –

RULES FOR USING RULES FOR USING COMBINING VOWELSCOMBINING VOWELS
1. When the ending of the root word and the beginning of the suffix are both consonants, use a combining vowel.
Example – hemat/o/logy
2. When the ending of the root word is a consonant, and the beginning of the suffix is a vowel, do not use a combining vowel.
Example – gastr/itis
1. When the ending of the root word and the beginning of the suffix are both consonants, use a combining vowel.

3. A combining vowel is always used when two root words are joined.
Example – cardi/o/thorac/ic
4. A prefix does not require a combining
vowelExample – epi/gastr/ic

Determine a medical word’s meaning by looking at the component pieces.Start at the suffix (all medical terms will
have one)Identify if there is a prefix (not all medical
terms will have one)Locate the root words (there may be more
than one)Identify the meaning of each word part as
you separate them

In medicine, spelling is critical!!!
One wrong letter could mean an entirely different place on the body or test to be performed
Examples – ilium and ileum, PAC and PVC, etc…

TIME TO PRACTICE!!!TIME TO PRACTICE!!!TIME TO PRACTICE!!!TIME TO PRACTICE!!!1. In order to break words into their component parts,
you will need to become familiar with Appendix A in your textbook (starting on page 293).
2. Write the following words on your paper leaving 4 spaces between words: EndocardiumEndocardium PneumoniaPneumonia
3. Using the appendix, break each word into word parts by placing a line in between the breaks (a / pnea)
4. Then, define the meaning of each word part by using the definition in the appendix (a = no, not, without and -pnea = breathing)
5. Finally, write the definition of each medical word (apnea = without breathing or no breathing)
