Clairvoyant hit copper in disorder (9)
I believe the answer is:
prophetic
'clairvoyant' is the definition.
(similar in meaning)
'hit copper in disorder' is the wordplay.
'in disorder' indicates anagramming the letters.
'hit'+'copper'='hitcopper'
'hitcopper' is an anagram of 'PROPHETIC'.
(Other definitions for prophetic that I've seen before include "inspirational" , "Seeing what's going to happen" , "divination" , "Forecasting" , "Foretelling events" .)
