Fragment of reprimand is controversial in Ring (4)
I believe the answer is:
disc
'ring' is the definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Perhaps you can see an association between them that I can't see?
'fragment of reprimand is controversial' is the wordplay.
'fragment of' indicates a hidden word (I've seen this in other clues).
'DISC' can be found hidden inside 'reprimand is controversial'.
'in' is the link.
Can you help me to learn more?
(Other definitions for disc that I've seen before include "Forty-five" , "Sound recording" , "Layer of cartilage between spinal vertebrae" , "Thin flat circular object" , "Thin circular plate, as in CD" .)
