Which suffix is used for the process of softening?

The suffix that denotes the process of softening is "-malacia." This term is derived from the Greek word "malakos," which means "soft." In medical terminology, it is commonly used to describe conditions where there is a softening of tissues or organs, often indicating an abnormality. For example, "chondromalacia" refers to the softening of cartilage. Understanding this suffix helps in recognizing various medical conditions that involve tissue changes, particularly in the context of diagnoses and treatment options.

The other choices represent different medical concepts: "-itis" refers to inflammation, such as in "arthritis," indicating swelling and pain; "-oma" signifies a tumor or growth, as seen in "neuroma," which denotes a nerve tumor; and "-pathy" means disease or disorder, as in "neuropathy," which refers to nerve damage or disease. Therefore, the use of "-malacia" is specifically associated with softening, making it the correct answer in this context.
