The root meaning 'Ear' is which of the following?

• A. Tympan-
• B. Umbilic-
• C. Aur-
• D. Cillia

Answer: (C)

The concept tested is identifying the proper root that means ear. The form aur- comes from Latin auris, meaning ear, and shows up in terms like auricle (the visible external part of the ear) and auricular (relating to the ear). Tympan- refers to the eardrum or tympanic membrane, which is a part of the ear but not the whole ear, so it’s not the root for “ear” itself. Umbilic- means navel, not ear. Cilia are hairlike projections on cells, not related to the ear. So aur- is the correct root for ear.
