Without thinking about current incentive? (4,2,3,6)
I believe the answer is:
spur of the moment
'without thinking about current incentive?' is the definition.
I can't tell whether this definition defines the answer.
'about current incentive?' is the wordplay.
I cannot really understand how this works, but
'about' could be 'of' and 'of' is found in the answer.
'incentive?' could be 'spur' (an incentive spur) and 'spur' is present in the answer.
This may be the basis of clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for spur of the moment that I've seen before include "in-form player at White Hart Lane?" , "Possibly Gareth Bale" , "Impulsive" , "Unplanned" , "impulse?" .)
