Mad about Queen and Wedgwood, perhaps (7)
I believe the answer is:
pottery
This clue might be a double definition.
'mad about queen' is the first definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
'wedgwood perhaps' is the second definition.
(Wedgwood is a manufacturer)
'and' acts as a link.
(Other definitions for pottery that I've seen before include "Earthenware" , "Ceramics factory" , "Items made from clay" , "China, for example" , "Items of fired clay" .)
