What does the suffix "-ology" refer to?

  1. Blood condition

  2. Breathe

  3. Study of

  4. Sweetness

The correct answer is: Study of

The suffix "-ology" is commonly used in the English language to denote the "study of" a particular subject or area of knowledge. For instance, biology refers to the study of life, while psychology refers to the study of the mind. This makes the choice referring to study of the correct answer, as it aligns perfectly with the definition of the suffix. The other options do not accurately reflect the meaning of "-ology." Blood condition, breathe, and sweetness refer to specific states or actions and do not pertain to the concept of studying or analyzing a discipline. This distinguishes the meaning of "-ology" as a suffix that emphasizes inquiry and academic exploration in various fields.
