Doctor following directions to Bury (6)
I believe the answer is:
entomb
'bury' is the definition.
('entomb' can be a synonym of 'bury')
'doctor following directions to' is the wordplay.
'doctor' becomes 'mb' (Bachelor of Medicine, Medicinae Baccalaureus).
'following' means one lot of letters go next to another.
'directions' becomes 'en' (I've seen this in other clues).
'en'+'to'='ento'
'mb' after 'ento' is 'ENTOMB'.
(Other definitions for entomb that I've seen before include "shut up patients?" , "Lay to rest in an underground vault" , "Place in a sepulchre" , "Cover - bury - hide" , "Inter" .)
