See spinners spinning (4)
I believe the answer is:
spot
'see' is the definition.
(thesaurus)
'spinners spinning' is the wordplay.
'spinners' becomes 'tops' (things that spin).
'spinning' says the letters should be written backwards.
'tops' in reverse letter order is 'SPOT'.
(Other definitions for spot that I've seen before include "See 12" , "Dot, stain" , "moral flaw" , "See; eruption" , "Catch sight of mark in pots" .)
