    • Change the meaning of medical terms

  • Suffix

    • Added to the end of a root/combining form

    • Use of combining vowel

  • Prefix

    • Added to the beginning of a medical term


Decoding terms
Decoding Terms

  • CARD Method

    • Check for the word parts in a term

    • Assign meanings to the word parts

    • Reverse the meaning of the suffix to the front of

      the definition

    • Define the term


Word analysis definition pronounciation
Word Analysis, Definition & Pronounciation

  • Analyze the following term:

    endocarditis

    1. suffix — itis meaning inflammation

    2. prefix endo— meaning inside

    3. root cardmeaning heart

    4. put the terms together—inflammation

    of the inside of the heart


Building terms
Building Terms

  • Spelling Rules

    • If the suffix starts with a vowel, a combining vowel is NOT needed to join the parts

      arthr/o itis = arthritis

    • If the suffix starts with a consonant, a combining vowel IS needed to join the two word parts

      arthr/o + plasty = arthroplasty


Building terms1
Building Terms

  • If a combining form ends with the same vowel that begins a suffix, one of the vowels is dropped

    Endo- + cardi/o + itis = Endocarditis

  • If two or more combining forms are used in a term, the combining form is retained

    Gastr/o + enter/0 + itis = Gastroenteritis


Building terms2
Building Terms

  • When two or more combining forms are used to make a medical term, special notice must be paid to the order in which the combining forms are joined

    Esophag/0 + gastr/o + duoden/o + scopy =

    Esophagogastroduodenoscopy

    (joining the CF reflects the direction in which the scope travels through the body)


Plurals
Plurals

  • Singular / Plural Rules

    • Ends in –a add –ae vertebraae

    • Ends in -is add –esarthrosises

    • Ends in –ix or –ex add –ices appendixices

    • Ends in –us add an –I digitusi

    • Ends in –y add –iesthearpyies
