What is the combining form vowel most commonly used in medical terminology?

The combining form vowel most commonly used in medical terminology is 'o'. This vowel is utilized to create medical terms by linking root words to suffixes and prefixes, making it easier to pronounce complex terms. For instance, in words like "cardiology" (the study of the heart), the root "cardi-" (heart) utilizes 'o' to connect with the suffix "-logy" (study of), enhancing the flow of the term and providing clarity in pronunciation.

While other vowels like 'a', 'i', and 'e' may appear in various medical terms, they do not serve as the primary combining form vowel across the majority of cases. The consistent use of 'o' reflects a standard practice in the formation of medical terminology, supporting healthcare professionals in effective communication and documentation.
