Drug doctor’s given journalist for fix (5)
I believe the answer is:
'fix' is the definition.
(I've seen this before)
'drug doctor's given journalist' is the wordplay.
'drug' becomes 'e' (e is another name for ecstasy).
'doctor' becomes 'mb' (Bachelor of Medicine, Medicinae Baccalaureus).
'given' means one lot of letters go next to another.
'journalist' becomes 'ed' (short for editor).
'for' acts as a link.
(Other definitions for embed that I've seen before include "Fix firmly in surrounding mass" , "war reporter" , "Fix fast in something solid" , "Implant (eg, an idea)" , "Surround" .)
