Entrance with roguish manner (7)
I believe the answer is:
archway
'entrance' is the definition.
(archway is a kind of entrance)
'with roguish manner' is the wordplay.
'with' is a charade indicator (letters next to each other).
'roguish' becomes 'arch' (I've seen this before).
'manner' becomes 'way' ('way' can be a synonym of 'manner').
'arch'+'way' is 'ARCHWAY'.
(Other definitions for archway that I've seen before include "part of London" , "entrance, perhaps" , "Entrance structure" , "Vaulted entrance; London tube station" , "Curved entrance" .)
