Badly given care generates complaint (9)
I believe the answer is:
grievance
'complaint' is the definition.
(I know that grievance is a type of complaint)
'badly given care' is the wordplay.
'badly' indicates an anagram (letters in the wrong order).
'given'+'care'='givencare'
'givencare' with letters rearranged gives 'GRIEVANCE'.
'generates' acts as a link.
(Other definitions for grievance that I've seen before include "Item causing resentment" , "Bad feeling" , "gripe" , "beef" , "Reason for dissatisfaction" .)
