Female childminder talked of problem reversing mischief (11)
I believe the answer is:
shenanigans
'mischief' is the definition.
(I've seen this before)
'female childminder talked of problem reversing' is the wordplay.
I cannot really see how this works, but
'female' could be 'she' ('she' refers to a woman) and 'she' is found within the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for shenanigans that I've seen before include "Monkey business" , "dirty work!" , "Mischief; dishonest activity" , "Mischievous trickery" .)
