What might be compact disc? (6)
I believe the answer is:
mirror
'be compact disc?' is the definition.
(I've seen this in another clue)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for mirror that I've seen before include "Image reflector" , "model" , "Reflect" , "copy of > tabloid" , "Common device for reflection" .)
