  13. 13. Word Roots<br />A word root is the foundation of a medical term and contains its primary meaning.<br /> All medical terms have at least one root.<br /> Mostword roots are derived from Greek or Latin language. Because of the this, two different root may have the same meaning.<br />As a general rule:<br /> Greek roots are used to build words that describe a disease, condition, treatment, or diagnosis.<br /> Latin roots are used to build words that describe anatomical structures.<br />Example:<br />
  14. 14. Combining Forms<br />A combining form is created when a word root is combined with a vowel.<br /> The word root plus this combining vowel is what<br /> creates the combining form.<br /> The combining form is the basic foundation to which<br /> other word elements are added to build a complete<br /> medical word.<br /> p. 3 (table )<br />The vowel is known as a combining vowel, an “o”, this vowel has no meaning but enables to word elements to be connected.<br />Example:<br />
  15. 15. Suffixes<br />A suffix is a word element placed at the end of a word that changes the meaning of the word.<br /> In medical terms a suffix usually describes a pathology (disease or abnormality), symptoms, surgical or diagnostic procedures, or part of speech.<br />These suffixes completely change the meaning of the medical word.<br />See the full list of suffixes on p. 14<br />Example:<br />
  16. 16. Prefixes<br />A prefix is a word attached to a word or word root.<br /> Not all medical terms have a prefix.<br /> A prefix usually indicates a number, time,<br /> position, direction or negation. <br />Adding and/or changing a prefix completely changes the meaning of the medical word.<br />See the full list of prefixes on p. 30<br />Example:<br />
  17. 17. Medical Words<br /> There are three basic steps for defining medical words.<br /> There are three basic rules for building medical words.<br />Guidelines<br />Defining and Buildingmedical words are crucial skills in mastering medical terminology.<br />Defining Medical words:<br />Building Medical words:<br />
  18. 18. Defining Medical Words<br />Gastroenteritis<br /> 1.) Inflammation 2.) stomach 3.) intestine<br />Inflammation of stomach and intestine.<br />Osteochondritis<br /> 1.) Inflammation 2.) bone 3.) cartilage<br />Inflammation of bone and cartilage.<br />Three Basic Steps<br />1.) Define the suffix (last part of word)<br /> 2.) Define the first part of the word (which could be a word, word root, combining form, or prefix)<br /> 3.) Define the middle parts of the word.<br />Examples:<br />
  19. 19. Building Medical Words<br />Three Basic Rules<br />Rule: 1.) A word root links a suffix that beings with a vowel.<br />Ex:<br />Rule: 2.) A combining form (root + o) links a suffix that beings with a vowel.<br />Ex:<br />Rule: 3.) A combining form links a root to another root to form compound words. *this rule holds true even if the next root starts with a vowel.<br />Ex:<br />
