Question

which word part means \hearing\? labrinth/o -cusis xero- -opia

Explanation:

• labrinth/o: This word part is related to the labyrinth (a complex structure, often referring to the inner ear's labyrinth in medical terms but not directly meaning "hearing").
• -cusis: This suffix specifically means "hearing". For example, in the word "presbycusis" (hearing loss due to age), it clearly relates to the concept of hearing.
• xero-: This prefix means "dry", as in "xeroderma" (dry skin).
• -opia: This suffix is related to "vision", like in "myopia" (nearsightedness).
