Which suffix refers to "the study of" in a medical context?

The suffix that refers to "the study of" in a medical context is -logy. This suffix is derived from the Greek word "logos," which means "word" or "discourse," but in a scientific context, it often denotes the study of a particular subject. For instance, terms like "biology" (the study of life), "physiology" (the study of bodily functions), and "psychology" (the study of the mind) all utilize this suffix to signify the discipline's focus.

In contrast, the other suffixes do not convey the meaning of study. The suffix -oid means "resembling" or "like," which may describe shapes or forms. The suffix -oma refers to a tumor or swelling, often denoting abnormal cell growth, typically in a specific context, such as "melanoma." The suffix -genetic relates to origin or production, often pertaining to heredity or genetic factors, as seen in terms like "genetic" or "carcinogenic." Understanding these distinctions helps clarify the correct terminologies used in the medical field.
