“Look again”, said Queen Jane (7)
I believe the answer is:
'queen jane' is the definition.
(Jane Seymour, third wife of Henry VIII)
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for seymour that I've seen before include "15 [JANE], one of the wives" , "Jane --, queen" , "See 15" , "Jane -, mother of Edward VI" , "Jane -, third wife of Henry VIII" .)
