Which prefix means Star-Shaped?

• A. Kerat-
• B. Astr-
• C. Phage-
• D. Pneum-

Answer: (B)

Star-related meaning is carried by astr-, from the Greek astron meaning star. In medical terminology, astr- is the combining form you’ll use when a term is linked to stars or star-like concepts, which is why it best fits “Star-Shaped” among the given options. The other prefixes line up with different ideas: kerat- refers to horn or the cornea, phage- means to eat, and pneum- relates to air or the lungs. If you’ve seen aster-, you’ll recognize it as the form more literally meaning star-shaped, but astr- is the closest star-related prefix available here.
