Having wasted time, daughter married (7)
I believe the answer is:
dallied
'having wasted time' is the definition.
'daughter married' is the wordplay.
'daughter' becomes 'd'.
'married' becomes 'allied'.
'd'+'allied'='DALLIED'
(Other definitions for dallied that I've seen before include "Dialled up, having delayed" , "Dawdled or wasted time" , "Held back" , "Hung about" , "moved slowly" .)
