Manner or fashion (3)
I believe the answer is:
way
This clue is a double definition.
'manner' is the first definition.
(I know that manner can be written as way)
'fashion' is the second definition.
(I know that fashion can be written as way)
(Other definitions for way that I've seen before include "Street" , "'Manner, mode (3)'" , "Method; route" , "Path" , "Manner; road" .)
