What suffix is indicative of a sensation of pain or sorrow?

The suffix that signifies a sensation of pain or sorrow is "-algia." This suffix is derived from Greek, where "algos" means pain. It is commonly used in medical terminology to describe conditions associated with pain in specific areas of the body, such as in "neuralgia" (pain in the nerves) or "myalgia" (muscle pain). The use of "-algia" effectively communicates the experience of discomfort or suffering linked to a certain condition, making it a precise component in the medical lexicon regarding pain.

The other suffixes listed do not specifically denote pain or sorrow. For example, "-pathy" refers to a disease or disorder, while "-itis" designates inflammation. Each of these suffixes serves a different purpose in medical terminology, but "-algia" is the specific term that directly relates to the sensation of pain.
