Using Word Parts…

  • Suffixes (S): the word ending

    • Changes the meaning of a word…you can make a word a noun, verb, or adjective

      • -ectomyexcision/surgical removal

Using Word Parts…

  • Word Root (WR): the basic meaning of the term

    • Typically indicates a body part, but not always

    • All medical terms must have one or more word roots

      • neur/onerve

      • cost/orib

      • oste/obone

      • erythr/ored

Using Word Parts…

  • Combining Vowel

    • Usually an “o”

    • Used between word roots or when a suffix begins with a consonant.

    • Examples:

      • Neurology

        • neur/o + -logy

      • Osteocyte

        • oste/o + -cyte

      • Neural (drop the combining vowel)

        • neur/o + -al
