The suffix meaning specialist is?

• A. -otomy
• B. Proct-
• C. -ologist
• D. Aden-

Answer: (C)

The suffix that denotes a specialist is -ologist. When you add -ologist to a root, you get a word for a person who studies or specializes in that area, like dermatologist (skin specialist) or cardiologist (heart specialist). The other options don’t signal a person who practices in a field: -otomy means a cutting or surgical procedure, proct- is a combining form related to the rectum, and aden- is a combining form related to glands. So the form that specifically names a specialist is -ologist.
