16. How Can I Determine the Meaning of a Word Just by Looking At It? Take the term apart Guess Use a medical dictionary Look on the net

17. Using a Medical Dictionary Spelling  If you don’t know how to spell the word, sound it out and write it down  If that doesn’t work, look for alternative spellings based on the beginning sound

18. Spelling ACCURACY is extremely important Changing just one or two letters can change the entire meaning of a word  Example: “ileum” is a part of the small intestine, and “ilium” is part of the hip bone

19. Pronunciation New terms will be written in bold The pronunciation will be in parentheses Just say the word like it is written in the parentheses The part that receives the most emphasis will be in BOLD CAPITAL LETTERS The part with secondary emphasis will be in bold lowercase letters

22. gastroenteritis root cv root suffix gastr/o/enter/itis stomach / small intestine /inflammation of Inflammation of the stomach & small intestine

23. Singulars and Plurals There are unusual rules for changing a singular word into a plural one The rules are foreign to us because most medical terms are of Greek or Latin origins

24. The Rules If a word ends in “a”, the plural will have an “e” added. Ex. Bursa to bursae If it ends in “ex” or “ix”, change it to “ices”  Ex. Appendix becomes appendices If the term ends in “um”, change it to an “a”  Ex. Ovum changes to ova See table 1.6 for the others

25. Don’t Panic!!!! All of these rules may seem overwhelming, but they will soon become second nature If in doubt, look for the plural form in a medical dictionary

26. Abbreviations Frequently used as a short-hand method of writing long and complex words or phrases Some can be confusing, so watch out!  Example: BE means “below elbow” and “barium enema”  A patient would be UPSET if these two terms were confused!
