Correct, ordinarily, about cleric (6)
I believe the answer is:
'cleric' is the definition.
'correct ordinarily about' is the wordplay.
'about' indicates a hidden word.
'RECTOR' can be found hidden inside 'correct ordinarily'.
(Other definitions for rector that I've seen before include "Churchman", "Parson", "Preacher Man", "Type of clergyman", "Cleric".)
