Which term is associated with the combining form "morbid/o"?

The combining form "morbid/o" is derived from the Latin word "morbidus," which means "sick" or "diseased." This term is commonly used in medical terminology to refer to conditions that involve illness or disease. Therefore, the term associated with this combining form is "ill," indicating a state of being unhealthy or affected by a disease.

Understanding the root "morbid" is crucial since it conveys the idea of abnormality or disease, especially in contexts such as morbid obesity or morbid anatomy. These terms suggest a serious or abnormal state related to health. Other options do not connect with the idea of illness: "death" refers to the cessation of life, "mucus" pertains to a thick fluid produced by mucous membranes, and "muscle" relates to tissue responsible for movement. Hence, "ill" is the most appropriate answer aligned with the meaning of "morbid/o."
