Medical Terminology word building

intro

  • 4 elements: word root, combining form, suffix and prefix
  • 3 rules of work rood building: defining, pronunciation and suffix s → p

word root - main meaning/foundation

  • from latin or greek
    • ex hepat in hepat/itis
  • contain at least 1 word root
  • usually tells body part
    • ex cardi = heart

combining form - word root + vowel

  • makes it easier to pronounce, no relation to word
    • ex. psych + o in psych/o/logy

suffix - end of word

  • changes meaning
  • usually indicates pathology, condition, symptom, therapeutic, diagnostic procedure or part of speech (noun vs adj)
    • ex -ectomy in append/ectomy

prefix - beginning of word

  • changes meaning
    • not in all med words
  • usually indicates number, time, position, measurement, direction or negotiation
    • ex hyper in hyper/tension

3 steps to define:

  • suffix, first part of word (wr, cf or p) then define middle part (wr or cf)
    • ex gastr/itis - inflammation of stomach

3 building rules:

  • wr links s that begins with a vowel
  • cf (root + o) links s that begins with consonant
  • cf (root + o) lniks a root to another root to form a compound word
