Blame accepted by doctor having a drink (6)
I believe the answer is:
grappa
'a drink' is the definition.
(type of alcoholic drink)
'blame accepted by doctor' is the wordplay.
I cannot quite see how this works, but
'blame' could be 'rap' (synonyms) and 'rap' is found within the answer.
'accepted' could be 'a' (financial abbreviation) and 'a' is found within the answer.
'doctor' could be 'gp' (general practitioner) and 'gp' is found in the remaining letters.
This accounts for all the letters.
This may be the basis of the clue (or it may be nonsense).
'having' is the link.
Can you help me to learn more?
(Other definitions for grappa that I've seen before include "Spirit distilled from grapes" , "Form of brandy" , "Italian brandy distilled from grape lees" , "Brandy from fermented pressed grape residue" , "Italian firewater" .)
