Which suffix describes abnormal hardening?

• A. rrhaphy
• B. scopy
• C. stenosis
• D. sclerosis

Answer: (D)

In medical terms, the suffix tells you what kind of condition or process is occurring. Sclerosis means abnormal hardening of tissue, so when this suffix is attached to a root like arterio- or oste-, it describes a state of hardening that’s not normal. That’s why this suffix is the best match for describing abnormal hardening.

The other suffixes describe different things: rrhaphy means suturing; scopy means looking or examining with a scope; stenosis means narrowing or constriction.
