Struggled to see what leads woman to leave daughter (4)
I believe the answer is:
vied
'struggled' is the definition.
(I've seen this in other clues)
'leave daughter' is the wordplay.
'leave' becomes 'vie' (I can't explain this - if you can you should believe this answer much more).
'daughter' becomes 'd'.
'vie'+'d'='VIED'
'to see what leads woman to' is the link.
I am not very happy about this link. Some or all of it may belong to another bit of the clue.
(Other definitions for vied that I've seen before include "Contested in dive" , "'Competed, contended (4)'" , "Competed in dive" .)
