Thought to fight with wife (4)
I believe the answer is:
view
'thought' is the definition.
(synonyms)
'fight with wife' is the wordplay.
'fight' becomes 'vie' (I've seen this in other clues).
'with' is a charade indicator (letters next to each other).
'wife' becomes 'w'.
'vie'+'w'='VIEW'
'to' is the link.
(Other definitions for view that I've seen before include "See" , "What can be seen from a specified point" , "Outlook" , "Aspect - prospect" , "Perspective" .)
