Ophelia prone to hog part of stage (5)
I believe the answer is:
apron
'stage' is the definition.
(thesaurus)
'ophelia prone to hog part' is the wordplay.
'part' indicates the answer is hidden within the clue.
'APRON' can be found hidden inside 'ophelia prone hog'.
'of' is the link.
(Other definitions for apron that I've seen before include "Protective garment worn at front" , "Protective garment in kitchen" , "edge" , "standing" , "conveyor-belt" .)
