LEARNING TO READ A MEDICAL TERM
When you look at a medical term and attempt to decipher its meaning you begin with the suffix, move to the prefix (if present) and then the root word.
For example: When trying to understand the word pericarditis you would identify itis (meaning inflammation), then peri (meaning around)and then card (meaning heart). Therefore, this word means inflammation around the heart.
Let’s try another one: for example: leukocytopenia - penia (meaning decrease), then leuk/o (meaning white)and finally cyt/o (meaning cell). Therefore, this word means a decrease in white cells.
