Modern; novel (3)
I believe the answer is:
new
I believe this is a double definition.
'modern' is the first definition.
(I know that modern can be written as New)
'novel' is the second definition.
(I know that novel can be written as new)
(Other definitions for new that I've seen before include "Fresh, unused" , "Modern" , "Original" , "Unfamiliar, restored" , "'Fresh, novel (3)'" .)
