Times goes on being a favourite of the Queen (5)
I believe the answer is:
essex
'a favourite of the queen' is the definition.
I can't tell whether this defines the answer.
'times goes on being' is the wordplay.
'times' becomes 'x' (s times e is s x e).
'goes on' says to put letters next to each other.
'being' becomes 'esse' (philosophical term for being or existence).
'x' put after 'esse' is 'ESSEX'.
Can you help me to learn more?
(Other definitions for essex that I've seen before include "Southeastern English county" , "County near London" , "County NE of London" , "R. Devereux, Earl of -" , "Chelmsford's county" .)
