Let’s see how this works by dissecting.  Prefixes A prefix is the first part of a medical word. It can be attached to the beginning of the root dysphagia Phag (Greek [φάγος] (phagos), ia swallowing A condition  Prefix + Root Hypertrophy Prefix Root "excessive growth," hyper- "over, exceedingly, to excess" + trophy “growth" Excessive growth in an organ or tissue due to increase in cell size, not in cell numbers.  Combining Forms Combining Vowels Forms Vowels ▪ A combining form includes the vowel that has been added to the end of a word root. For example,gastr/o is the combining form of the word root for stomach. The letter “o”is the most commonly used combining vowel, and under certain conditions, this is added to make the resulting medical term easier to pronounce. The rules for the use of a combining vowel are: The rules for creating a combining form by adding a vowel apply when a suffix beginning with a consonant is added to a word root.
