Try to win the affections of (3)
I believe the answer is:
woo
'try to win the affections of' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for woo that I've seen before include "Try to get the girl?" , "Try to attract" , "Court, romance" , "Court (someone)" , "Court; importune" .)
