What does the suffix "-algia" indicate?

The suffix "-algia" is derived from Greek and is used in medical terminology to denote pain. When you see a term that includes this suffix, it typically refers to a specific type of pain associated with a particular body part or condition. For example, "neuralgia" refers to nerve pain, while "myalgia" refers to muscle pain. This suffix is a key element in understanding various medical conditions related to discomfort or pain in the body.

Other answers, while related to medical terms, reflect different concepts entirely: "incision" indicates a surgical cut, "study of" relates to "-ology," which signifies a discipline or field of study, and "enlargement" is represented by the suffix "-megaly." Thus, the correct option clearly identifies the specific meaning associated with "-algia" as pain.
