Fancy -- possibly late Norman (10)
I believe the answer is:
ornamental
'fancy' is the definition.
(I've seen this before)
'possibly late norman' is the wordplay.
'possibly' indicates an anagram.
'late'+'norman'='latenorman'
'latenorman' with letters rearranged gives 'ORNAMENTAL'.
(Other definitions for ornamental that I've seen before include "Fancy" , "non-functional" , "Plant grown for attractive appearance" , "Decorative" , "showy" .)
