Wife always shows style (3)
I believe the answer is:
way
'style' is the definition.
(I know that style can be written as way)
'wife always shows' is the wordplay.
'shows' indicates a hidden word.
'WAY' is hidden within 'wife always'.
(Other definitions for way that I've seen before include "Route; direction" , "Path" , "Street" , "'Manner, mode (3)'" , "Method; route" .)
