Does a combing vowel change the meaning of the term?

A combining vowel does not change the meaning of a medical term; instead, it facilitates pronunciation and connects Word parts. Typically, the combining vowel "o" is used when linking a root Word to a suffix or another root. For example, in "cardiology," the combining vowel "o" helps connect "cardio" (heart) and "logy" (study). Thus, while it aids in the flow of speech, it doesn't alter the fundamental meaning of the term.
