What is the foundation of a medical term?

• A. Word root
• B. Prefix
• C. Suffix
• D. Combining vowel

Answer: (A)

The main idea is that the word root is the core piece of a medical term. It carries the primary meaning, usually naming a body part or system. Prefixes add or modify that meaning (such as indicating location, number, or negation), while suffixes indicate a condition, disease, or procedure. The combining vowel simply links word parts together and helps pronunciation, but it doesn’t carry the essential meaning.

So, the term’s foundation is the word root because it provides the central idea: for example, gastr- refers to the stomach, and cardi- refers to the heart. When you add a suffix like -itis, you’re specifying the condition (inflammation) on that root’s meaning, as in gastritis. The linking vowel helps connect the pieces but does not change the core meaning carried by the word root.
