Fancies Delaware fathers (7)
I believe the answer is:
desires
'fancies' is the definition.
(I've seen this in another clue)
'delaware fathers' is the wordplay.
'delaware' becomes 'DE' (standard two letter abbrev).
'fathers' becomes 'sires' ('sire' can be a synonym of 'father').
'de'+'sires'='DESIRES'
(Other definitions for desires that I've seen before include "Covets and yearns for" , "Wants (7)." , "Wishes" , "needs" , "Hopes" .)
