Troublemaker gets to work creating strong effects (7)
I believe the answer is:
impacts
'strong effects' is the definition.
'impacts' can be an answer for 'effects' (impact is a kind of effect). I'm not certain of the 'strong' bit.
'troublemaker gets to work' is the wordplay.
'troublemaker' becomes 'imp' (little devil).
'gets' means one lot of letters go next to another.
'to work' becomes 'acts' (I have seen 'spiritual work' mean 'acts' so perhaps 'work' could also mean 'acts').
'imp'+'acts'='IMPACTS'
'creating' acts as a link.
Can you help me to learn more?
(Other definitions for impacts that I've seen before include "Bumps into, collides with" , "Collisions of jolts" , "It's camp (anag)" .)
