What is the meaning of the prefix Therap-?

• A. Ureter
• B. Two
• C. Therapy
• D. Base

Answer: (C)

The meaning being tested is the idea that this combining form is all about treatment and healing. Therap- comes from a Greek root related to healing and attending to illness, so it appears in words that describe how something is treated—therapy, therapeutic, therapist, therapeutics, and similar terms. That’s why the best choice is therapy, since it directly conveys the notion of treatment or the act of healing.

Ureter, two, and base refer to completely different ideas: ureter is a part of the urinary system, two points to a number, and base is a foundational term. None of those share the healing/treatment sense that Therap- carries.
