What does the prefix "logy" refer to?

The prefix "logy" is derived from the Greek word "logia," which means "the study of" or "the science of." Therefore, when it is used as a suffix in various scientific and academic disciplines, it denotes a field of study or an organized body of knowledge pertaining to a specific subject. Common examples include "biology" (the study of life), "geology" (the study of the Earth), and "mycology" (the study of fungi).

Understanding the meaning of "logy" is crucial in comprehending various scientific terminologies, as it frequently indicates that the term involves a systematic examination or investigation of the topic. The other options refer to specific concepts: "life" relates to biology, "cell" relates to cellular biology, and "stomach" pertains to anatomy and physiology, but none of these directly translate to the general concept of "the study of" that "logy" embodies.
