Which suffix indicates an abnormally large condition?

The suffix that indicates an abnormally large condition is "-megaly." This term is derived from the Greek word "megas," meaning large or great. In medical terminology, it is commonly used to describe the enlargement of specific organs or structures in the body. For example, "hepatomegaly" refers to an enlarged liver, while "cardiomegaly" refers to an enlarged heart. The use of this suffix effectively communicates that a particular organ or body part is larger than normal, which can be indicative of various medical conditions.

The other options do not relate to size. The suffix "-rrhage" pertains to excessive flow or bleeding, often used in terms like "hemorrhage." The suffix "-tox" is related to poison or toxic substances, as seen in "neurotoxic." Lastly, "-splen" refers to the spleen and is not a suffix that indicates size. Understanding these distinctions helps clarify medical terms and their meanings in a clinical context.
