Aces high, for example (4)
I believe the answer is:
case
'example' is the definition.
(thesaurus)
'aces high' is the wordplay.
'high' indicates anagramming the letters (can mean drunk or on drugs and hence disordered).
'aces' is an anagram of 'CASE'.
'for' acts as a link.
(Other definitions for case that I've seen before include "proceedings" , "Legal action; container" , "See 12" , "A proceeding in a court of law" , "Action taken" .)
