3. MEDICAL TERMINOLOGY The process of dividing medical words into component parts. Analysis of words will make medical terminology easier to understand and remember.

4. ORIGINSORIGINS Word parts generally come from two language origins: Greek Latin Word parts generally come from two language origins: Greek Latin

5. 5 BASIC WORD PARTS Root words Suffixes Prefixes Combining vowel Combining form Root words Suffixes Prefixes Combining vowel Combining form

6. ROOT WORD Root Word – foundation of the word, usually indicates the involved body part Examples: cardi -  thorac- cephal – gastr – cyt – A medical term can have one or more root words. Ex. – cardi/o/thorac/ic = pertaining to heart and chest Root Word – foundation of the word, usually indicates the involved body part Examples: cardi -  thorac- cephal – gastr – cyt – A medical term can have one or more root words. Ex. – cardi/o/thorac/ic = pertaining to heart and chest

7. SUFFIXES are… Word ending; usually indicates a procedure, condition, disorder or disease. Read from the suffix backwards to the root word for the correct meaning. Suffixes can be nouns or adjectives **All medical words have suffixes Examples: -itis-ic -logy-lysis Word ending; usually indicates a procedure, condition, disorder or disease. Read from the suffix backwards to the root word for the correct meaning. Suffixes can be nouns or adjectives **All medical words have suffixes Examples: -itis-ic -logy-lysis

8. PREFIXES are… Word beginning; usually indicates location, time, or a number **Not all medical words have prefixes Examples: Epi- pre- hyper- sub- Word beginning; usually indicates location, time, or a number **Not all medical words have prefixes Examples: Epi- pre- hyper- sub-

9. COMBINING VOWELS AND FORMS 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 – 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 –

10. RULES FOR USING COMBINING 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 – Study of Blood 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- inflammation of the stomach 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 – Study of Blood 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- inflammation of the stomach

11. RULES FOR USING COMBINING VOWELS 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 vowel Example – epi/gastr/ic = ??? __________________________________

12. TAKING TERMS APART 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 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

13. TAKING TERMS APART Remember! If you have any doubt about the correct meaning of a word, USE a medical dictionary (appendix, internet) to double check the definition.
