She's entitled to swill mead (4)
I believe the answer is:
dame
'she's' is the definition.
Both the answer and definition are singular nouns.
Perhaps there's a link between them I don't understand?
'entitled to swill mead' is the wordplay.
'mead' can be anagrammed to 'DAME'.
But, I'm unsure how this is indicated.
Can you help me to learn more?
(Other definitions for dame that I've seen before include "Pantomime lady" , "Titled lady" , "British title for a lady" , "Lady's title" , "Peeress" .)
