Which suffix means disease?

• A. -graphy
• B. -ology
• C. -pathy
• D. -rrhea

Answer: (C)

When you break down medical terms, the ending often tells you what’s happening. The suffix that signals a disease or disorder is -pathy. It appears in words like neuropathy (nerve disease), cardiopathy (heart disease), and myopathy (muscle disease), showing that a problem is present in that body part. The other endings have different meanings: -graphy means recording or imaging, -ology means the study or science of, and -rrhea means a flow or discharge. So -pathy is the best fit here because it directly indicates a disease or disorder.
