Brooded over when drunk (6)
I believe the answer is:
stewed
This might be a double definition.
'brooded over' is the first definition.
'stewed' can be an answer for 'brooded' ('stew' can be a synonym of 'brood'). I am not sure about the 'over' bit.
'drunk' is the second definition.
(thesaurus)
'when' is the link.
Can you help me to learn more?
(Other definitions for stewed that I've seen before include "Cooked (prunes?)" , "Of tea, left brewing too long" , "Of tea, infused too long" , "Cooked slowly" , "Cooked in hot water" .)
