Answer:
If i remember correctly the pronouciation will differ depending on the combining vowel or the rules
Step-by-step explanation:
combining vowel - vowel (usually " o " ) added to a root ( ex: gastro )
Combinding form rules
"o" between word root & suffix
if the suffix begins w/ a constant use a combining vowel
arthr/ o / scope ( because it is not spelled/pronounced > arthrscope )
if the suffix begins w/ a vowel DO NOT use a combining vowel
arthr/itis ( because it is NOT spelled/ pronounce > arthroitis )
I hope this helps
