RECOGNIZING WORD ELEMENTS HEALTHCARE Sixty percent of English words have been adapted from Latin and Greek. The Latin and Greek languages use a system of word parts, or word elements, that can be used alone or in combination in order to form words. As the combinations of the word parts change, so does the meaning of the words. Many medical terms are made up of these word parts – so by knowing the meaning of the word part will enhance your understanding of a medical term. Just think about how many more words you’ll understand by learning roots and affixes. IMPORTANT TERMS: ROOT: is the stem or basic part of the word which carries the main meaning of the word. The root -derm- means: skin The root -ven- means: vein PREFIX: is a word part or group of letters added on to the beginning of a root which can change the meaning of that root or word. The prefix intra-, intro- means within intravenous = relates to something within the vein intramuscular = relates to something within the muscle The prefix hypo- means under, below hypoderm = relates to something below the skin SUFFIX: is a word part or group of letters added to the end of a root which can alter the word’s form or part of speech – such as change from a noun to a verb. Nearly all medical terms have a suffix. The suffix –algia,-dynia means pain The suffix –ectomy means excision (cut out) neuralgia = relates to nerve pain appendectomy = relates to removal of the appendix AFFIX: refers to the word parts that are added to a root; another name for prefix and/or suffix Intra + ven + ous + ly = “a drug, solution, or other substance administered into a vein” Hypo + derm + ic = relating to the “introduction of drugs or medicine under the skin” DERIVATIVE: a word that is formed using the various word parts gastro (stomach) = gastroenterology, gastroenterologist -logy (study) = psychology, cardiology, neurology EXAMPLES OF WORD PARTS AND THEIR DERIVATIVES: myocarditis GYNE pancreatitis (female) Inflammation Gynecology gynecologist gynecological osteoarthritis Use with Chapter 10, Introduction to Health Care and Careers, by Roxann DeLaet
