Daughter took food for boyfriend (4)
I believe the answer is:
date
'for boyfriend' is the definition.
(someone's date might be a boyfriend)
'daughter took' is the wordplay.
'daughter' becomes 'd' (genealogical abbreviation).
'took' becomes 'ate' (eating is a kind of taking).
'd'+'ate'='DATE'
'food' acts as a link.
This may not be right. It may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for date that I've seen before include "A social appointment - check calendar" , "Sweet fruit with a long woody seed" , "Court" , "Rendezvous" , "Specified day" .)
