Turners to turn and turn (4)
I believe the answer is:
spot
'turn' is the definition.
The definition and answer can be both acts as well as being singular nouns.
Perhaps you can see an association between them that I don't see?
'turners to turn' is the wordplay.
'turners' becomes 'sp' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'turn' says the letters should be written in reverse.
'to' reversed gives 'ot'.
'sp'+'ot'='SPOT'
'and' acts as a link.
Can you help me to learn more?
(Other definitions for spot that I've seen before include "See 5" , "Notice; mark" , "Observe - place" , "See; round mark" , "Detect" .)
