What does the suffix "-ous" generally indicate in medical terminology?

The suffix "-ous" is commonly used in medical terminology to indicate a relationship or pertaining to a certain condition. When this suffix is added to a root word, it often implies that something is characteristic of, or has the qualities of, the noun it modifies.

For example, in the term "muscular," the suffix "-ous" signifies that the subject relates to muscles. In another term, "nervous," it conveys that the characteristic pertains to the nerves. This understanding helps in correctly interpreting and understanding various medical terms that involve this suffix, enhancing communication within the medical field.

Other options present variations that do not align as closely with the meaning of "-ous." While "full of" can represent a certain quality, it does not capture the broader sense of relation that "-ous" indicates. Similarly, "condition of" and "referring to" lack the specific nuance that directly ties to the idea of pertaining to an aspect of medicine or health. Thus, the choice of "pertaining to" is the most accurate reflection of what the suffix "-ous" signifies in medical terminology.
