Where one may eat around event, one in Royal Academy (9)
I believe the answer is:
cafeteria
'where one may eat' is the definition.
Although both the answer and definition are singular nouns, I can't see how they can define each other.
'event one in royal academy' is the wordplay.
'event' becomes 'fete' (I have seen 'Charitable event ' mean 'fete' so perhaps 'event' could also mean 'fete').
'one in' indicates putting letters inside.
'royal academy' becomes 'caria' (I can't justify this - if you can you should give a lot more credence to this answer).
'fete' going into 'caria' is 'CAFETERIA'.
'around' is the link.
Can you help me to learn more?
(Other definitions for cafeteria that I've seen before include "eating-place" , "Canteen" , "place of refreshment" , "where food can be picked up" , "Place to eat" .)
