origins of medical language
Origins of medical language
  • Current medical vocabulary includes terms built from Greek and Latin word parts, some which were used by Hippocrates and Aristotle over 2000 years ago
slide6
Word Parts / Building Blocks
  • Medical terms are built from word parts with some or all of the following components:
  • Word roots
  • Suffixes
  • Prefixes
  • Combining vowels
  • Combining forms
word root
The word root is the foundation of the word

Usually indicates the part of the body involved

All medical terms

must have one or more word roots

Word Root
examples
Examples:
  • In the word…………………..play/er

(play is the word root)

  • In the medical term …………arthr/itis

arthr(which means joint) is the word root

  • In the medical term………….hepat/it is

hepat(which means liver) is the word root

suffixes
Suffixes
  • Suffix is the word part attached to the end of the word root to modify its meaning.
  • The suffix usually indicates the procedure, disease, or condition
  • All medical terms musthave a suffix.
examples1
Examples:
  • In the medical term…………..hepat/ic

-ic(which means pertaining to) is the suffix

The term hepatic means pertaining to the liver

  • In the medical term ………… hepat/itis

-itis(which means inflammation) is the suffix

The term hepatitis means inflammation of the liver (inflammation being a condition)

prefix
Prefix
  • The prefix is a word part that is attached to the beginning of the word root to modify its meaning.
  • It usually indicates location, time, color, or number
  • Not all medical terms have prefixes
examples2
Examples:
  • In the word ………………...re/play

re- is the prefix

  • In the medical term ………sub /hepat /ic

sub- (which means under)

The medical term subhepatic means pertaining to under the liver

combining vowel
Combining Vowel
  • It links the root to the suffix or the root to another root
  • The combining vowel is usually an “O”
  • A combining vowel has no meaning of its own. It just joins word parts and makes them easier to pronounce
combining vowels
Combining vowels
  • Guideline #1:
    • When connecting a root and a suffix a combining vowel is used unless the suffix begins with a vowel
    • Guideline #2:
        • When connecting two word roots, a combining vowel is usually used even if vowels are present at the junction
exercise 1
Exercise 1:

Complete the phrases with the correct word part:

  • A __ is attached at the beginning of a word root
  • ___ are usually an “o”
  • All medical terms contain one

or more ___

4. A ____is attached at the end of a word root.

5. The ______ _____ is the word root with the combining vowel attached

  • True or False
  • There is always a prefix at the beginning of a medical term
  • A combining vowel is always used when connecting a word root and a suffix
  • A prefix modifies the meaning of the word
  • A combining vowel is used to ease pronunciation
  • “I” is the most commonly used combing vowel
  • The word root is the core of a medical term
  • A combining vowel is used between a prefix and word root
  • A combining form is a word part
analyzing and defining medical terms
Analyzing and defining Medical Terms

osteoarthropathy

To analyze a medical term divide it into word parts, label each word parts, and label the combining forms.

Divide the word with slashes:

oste / o/ arthr / o/ pathy

Label each word part by using the following abbreviations:

WR WORD ROOT

P PREFIX

S SUFFIX

CV COMBINING VOWEL

example of dividing and labeling
Example of dividing and labeling:

WR CV WR CV S

Oste / o / arthr /o / pathy

  • To define medical terms apply the meaning of each word part in the term.
  • Begin by defining the suffix, then move to the beginning of the term to complete the definition
