Which suffix means 'Condition of; disease of; intensive'?

• A. -osis
• B. -stenosis
• C. -oma
• D. -spasm

Answer: (A)

The suffix that signals a condition or disease state is -osis. It names an abnormal condition or process and is used in many medical terms to describe the state of a body part or system, such as osteoporosis (porous bone condition) or cirrhosis (liver disease). The other suffixes point to different ideas: -stenosis means narrowing, -oma is a tumor or mass, and -spasm is a sudden, involuntary contraction. So -osis best fits the meaning “condition of; disease of.”
