    • Prefixes
    • Suffixes
    • Linking or combining vowels
word roots
Word Roots
  • Are the meaning or base of the term
  • Every medical term has at least one word root
    • Ex: hepatitis – hepat is the word root and means liver.

When you analyze a medical term, begin at the end of the word.

The ending of a word is called a suffix.

All medical terms contain suffixes.

Word Analysis
word analysis review
Word Analysis - Review
  • Root = gives the essential meaning of the term
  • Suffix = the word ending
  • Prefix = a small part added to the beginning of a term
  • Combining vowel = connects roots to suffixes and roots to other roots
  • Combining form = combination of the root and a combining vowel
word analysis rules
Word Analysis - Rules
  • Read the meaning of medical words from the suffix, then to the beginning of the word and across
  • Drop the combining vowel before a suffix that starts with a vowel
  • Keep the combining vowel between roots, even if the root begins with a vowel
expectations
Expectations
  • Every week you will be given new prefixes, roots or suffixes to learn.
  • You will need to be able to give the meaning the medical terms created from that list
  • You will need to be able to give the medical term if you are given the meaning
  • Spelling is important!
