Brave reorganisation of Hire Co (6)
I believe the answer is:
heroic
'brave' is the definition.
(thesaurus)
'reorganisation of hire co' is the wordplay.
'reorganisation of' is an anagram indicator (I've seen this in other clues).
'hire'+'co'='hireco'
'hireco' anagrammed gives 'HEROIC'.
(Other definitions for heroic that I've seen before include "Surpassing the ordinary, in courage say" , "Dramatic" , "Extravagant" , "Epic" , "Showing extreme courage" .)
