Way to caress husband? (4)
I believe the answer is:
path
'way' is the definition.
(path is a kind of way)
'caress husband?' is the wordplay.
'caress' becomes 'pat' (patting is a kind of caressing).
'husband?' becomes 'h'.
'pat'+'h'='PATH'
'to' is the link.
(Other definitions for path that I've seen before include "Pedestrian way" , "Trodden track" , "Established route" , "Way for pedestrians" , "Track; direction" .)
