What does the prefix 'PATH' indicate in medical language?

  1. Optical

  2. Light

  3. Disease

  4. Tension

The correct answer is: Disease

The prefix 'PATH' in medical terminology is derived from the Greek word "pathos," which means suffering or disease. Therefore, when you encounter this prefix in medical language, it typically indicates a relationship to disease states or disorders. For example, terms like "pathology" refer to the study of disease, and "pathogen" signifies an agent that causes disease. This context reinforces that the correct answer indeed reflects the meaning of 'PATH' as associated with disease.
