Reel turning goes round (5)
I believe the answer is:
spool
'reel' is the definition.
(synonyms)
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for spool that I've seen before include "Cylinder for winding film etc" , "Film reel; wind" , "Loops around a thread holder" , "Ribbon holder" , "Bobbin, reel" .)
