Representative in court? Try one at random (8)
I believe the answer is:
attorney
'representative in court?' is the definition.
(legal representative)
'try one at random' is the wordplay.
'random' indicates anagramming the letters.
'try'+'one'+'at'='tryoneat'
'tryoneat' is an anagram of 'ATTORNEY'.
(Other definitions for attorney that I've seen before include "US lawyer" , "Person appointed to act for another in legal or business matters" , "One can help in case" , "- jar; - tent; - metal" , "No treaty (anag.)" .)
