Question

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

Explanation:

• -opia: This suffix is related to vision. For example, "myopia" means nearsightedness.
• xero-: This prefix means dry. For example, "xeroderma" means dry skin.
• labrinth/o: This combining form refers to the labyrinth of the ear (a complex structure in the inner ear), but it is not directly the word part for "hearing".
• -cusis: This suffix specifically means hearing. For example, "presbycusis" means hearing loss due to age.

Answer:

-cusis
