What is the meaning of the suffix -ac?

• A. Absent
• B. End of a part
• C. Pertaining to
• D. Hear

Answer: (C)

Suffix -ac signals that a term describes something pertaining to or related to a specific root. In medical language, adding -ac to a root creates an adjective that tells you what that root concerns. For example, cardiac means pertaining to the heart, showing how the ending connects the concept to the organ. The other meanings listed don’t fit because -ac isn’t used to express absence, the end of a part, or hearing; those ideas come from different roots or suffixes.
