Which suffix conveys a meaning of affinity for something?

• A. -metry
• B. -mania
• C. -philia
• D. -ectomy

Answer: (C)

The suffix that conveys a meaning of affinity for something is "-philia." This suffix is derived from the Greek word "philia," meaning love or fondness. It is often used in medical terminology to describe a strong inclination or attraction towards a particular substance, condition, or concept. For example, "hemophilia" refers to a condition where there is a fondness or affinity for bleeding due to a deficiency in blood-clotting factors.

The other choices represent different meanings. The suffix "-metry" relates to the measurement of something, often used in words like "audiometry," which involves the measurement of hearing. The suffix "-mania" signifies an excessive preoccupation or obsession with a particular thing, as seen in "pyromania," which is a compulsion to set fires. Lastly, the suffix "-ectomy" indicates the surgical removal or excision of a body part, such as in "appendectomy," which is the removal of the appendix. Thus, "-philia" is uniquely associated with a positive affinity or attraction, making it the correct choice.
