Nominal
Nominal
Nominal (/nɒmɪnəl/; from the Latin nominālis, "of naming") is a term used in various fields of study, including linguistics, philosophy, and medicine. In the medical context, it refers to a condition or symptom that is named or classified but not fully understood or explained.
Etymology
The term "nominal" is derived from the Latin nominālis, which means "of naming". It is used to describe something that exists in name only, not in reality or substance.
Medical Usage
In medicine, a nominal diagnosis or symptom is one that is named or classified, but not fully understood or explained. This can occur when a patient presents with symptoms that do not fit into any known disease category, or when a disease is named based on its symptoms rather than its underlying cause. For example, Irritable Bowel Syndrome (IBS) is a nominal diagnosis because it is defined by a set of symptoms rather than a specific cause.
