Protestant disturbs real hunt (8)
I believe the answer is:
lutheran
'protestant' is the definition.
(I've seen this before)
'disturbs real hunt' is the wordplay.
'disturbs' is an anagram indicator (I've seen 'disturbed' mean this).
'real'+'hunt'='realhunt'
'realhunt' is an anagram of 'LUTHERAN'.
(Other definitions for lutheran that I've seen before include "it could be Bach" , "Protestant church member" , "Of the Protestant Reformation" , "Type of Protestant" , "Bach, for instance" .)
