What is the meaning of the suffix '-logy'?

• A. The science of
• B. The process of
• C. The study of
• D. The condition of

Answer: (C)

-logy signals a field focused on studying something. In medical terms, it marks the study or science of a subject, naming disciplines like cardiology (the study of the heart) or neurology (the study of nerves). That direct sense is why “the study of” is the best fit among the options. The suffix isn’t about a process or a condition; those ideas are expressed with different endings. It’s true that -logy can be described as the science of, but the core idea you’re aiming for is the study of something.
