Spinner, which is unaffected by spinning? (7)
I believe the answer is:
rotator
'spinner which is unaffected by spinning?' is the definition.
'rotator' can be an answer for 'spinner' (I've seen this in another clue). I'm not certain of the remainder of the definition.
'spinner which is unaffected by' is the wordplay.
I cannot really understand how this works, but
'by' could be 'at' and 'at' is found within the answer.
'spinner' could be 'rotor' (I've seen this before) and 'rotor' is found in the leftover letters.
This accounts for all the letters.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for rotator that I've seen before include "Muscle that revolves a part of the body on its axis" , "Device that spins" , "One palindromic turner ..." , "anatomical drawing may reveal such muscle" , "Something turning" .)
