What is the vowel used when a suffix starts with a consonant?

• A. Combining vowel
• B. Root vowel
• C. Prefix vowel
• D. Suffix vowel

Answer: (A)

The concept of a combining vowel is essential in medical terminology for the effective formation of terms. When a suffix begins with a consonant, a combining vowel, typically the letter "o," is used after the root word. This practice facilitates smoother pronunciation and clear understanding by preventing awkward combinations of consonants.

For example, when combining the root "neur" (relating to nerves) with the suffix "-itis" (inflammation), the combining vowel "o" is added to create "neuritis." This addition enables better auditory clarity and flow in the term. Thus, the identifying feature of a combining vowel is its role in effectively linking root words to suffixes or additional root words, especially when the suffix starts with a consonant.
