Get at aid corruptly in troubled state (8)
I believe the answer is:
agitated
'in troubled state' is the definition.
(I've seen this before)
'get at aid corruptly' is the wordplay.
'corruptly' indicates an anagram.
'get'+'at'+'aid'='getataid'
'getataid' with letters rearranged gives 'AGITATED'.
(Other definitions for agitated that I've seen before include "On edge, anxious" , "Tried to stir up public opinion" , "Worked up, flustered" , "beat" , "Troubled, perturbed" .)
