For instance, "-pathy" refers to disease or disorders of a specific organ (like "neuropathy" for nerve disease), "-oma" signifies a tumor or mass (such as "carcinoma" which is a type of cancer), and "-itis" denotes inflammation (for example, "appendicitis," which indicates inflammation of the appendix).
