New-style Morden (6)
I believe the answer is:
modern
'new' is the definition.
(I know that new can be written as Modern)
'style morden' is the wordplay.
'style' is an anagram indicator (style can mean to shape or design).
'morden' anagrammed gives 'MODERN'.
(Other definitions for modern that I've seen before include "Recent, up to date" , "Fashionable (like the new Tate gallery?)" , "Belonging to the present or recent times" , "In history, the period or era since the Middle Ages" , "See 11" .)
