The suffix '-logy' denotes?

• A. A suffix meaning fear.
• B. A suffix meaning excess.
• C. A suffix meaning study of; a branch of knowledge.
• D. The study of; a branch of knowledge.

Answer: (D)

The suffix -logy signals a field of study or science about something. It means the study of a subject or a branch of knowledge, which is why it appears in words like biology (the study of life) or geology (the science of the Earth). For this question, the most precise description is “the study of; a branch of knowledge,” because that phrasing directly captures both the act of studying and the area it belongs to. The other option would be close in meaning but doesn’t fit the standard dictionary-style expression as neatly. The idea behind -logy is that it names a field of knowledge formed by studying a particular subject.
