Which suffix is described as relating to abundance or presence?

• A. -osis
• B. -emia
• C. -ostomy
• D. -otomy

Answer: (A)

The suffix that marks a condition or state of being is -osis. It describes the presence or abundance of a process or disease in the body, turning a concept into a noun that names that condition. That makes it the best fit for “relating to abundance or presence” because terms like cirrhosis or psoriasis are naming the ongoing condition that is present in the organ or tissue. In contrast, -emia refers specifically to a blood condition, -ostomy means creating a surgical opening, and -otomy means making a surgical cut.
