The suffix -opia refers to which sense or function?

• A. Vision
• B. Hearing
• C. Breathing
• D. Pain

Answer: (A)

The idea being tested is how medical suffixes indicate what sense or function is involved. The ending -opia is tied to sight and vision. It comes from a root related to seeing, so terms with -opia describe eye-related conditions affecting vision, such as myopia (nearsighted) or hyperopia (farsighted). That’s why vision is the best fit. Other options point to different senses or functions: -acusia or -cusis relate to hearing, -pnea to breathing, and -algia to pain. So they don’t match the meaning of -opia.
