Driven to shaking after naughty child’s thoughtless (11)
I believe the answer is:
improvident
'thoughtless' is the definition.
(thesaurus)
'driven to shaking after naughty child's' is the wordplay.
'shaking' is an anagram indicator.
'after' is a charade indicator (letters next to each other).
'naughty child' becomes 'imp' (I've seen this before).
'driven'+'to'='drivento'
'drivento' anagrammed gives 'rovident'.
'rovident' put after 'imp' is 'IMPROVIDENT'.
(Other definitions for improvident that I've seen before include "unprepared for what's to come?" , "without forethought" , "Not thrifty" , "Lacking foresight - spendthrift" , "Thoughtless" .)
