Mistake made by troublesome child blowing top (5)
I believe the answer is:
error
'mistake' is the definition.
('error' can be a synonym of 'mistake')
'troublesome child blowing top' is the wordplay.
'troublesome child' becomes 'terror' (I've seen this before).
'blowing top' means to remove the first letter.
'terror' with its first letter taken away is 'ERROR'.
'made by' is the link.
(Other definitions for error that I've seen before include "Mistake or mishap" , "Miscarriage of justice" , "Gaffe" , "Blunder or mistake" , "heresy" .)
