Queen always follows a half of stout with tablet (9)
I believe the answer is:
guinevere
'queen' is the definition.
(King Arthur's queen)
'always follows a half of stout with tablet' is the wordplay.
I cannot really see how this works, but
'always' could be 'ever' (synonyms) and 'ever' is present in the answer.
'tablet' could be 'e' (E can mean ecstasy or an ecstasy tablet) and 'e' is located in the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for guinevere that I've seen before include "A mistress" , "Unfaithful queen" , "legendary paramour" , "legendary character)" , "legendary wife" .)
