Lost a daughter when having quarrel (6)
I believe the answer is:
adrift
'lost' is the definition.
(thesaurus)
'a daughter when having quarrel' is the wordplay.
'a daughter' becomes 'ad' (I've seen this in other clues).
'when having' is a charade indicator (letters next to each other).
'quarrel' becomes 'rift' (I've seen this in other clues).
'ad'+'rift'='ADRIFT'
(Other definitions for adrift that I've seen before include "Unsettled or unanchored" , "Loose from moorings" , "Moving aimlessly, unfastened" , "without purpose or direction" , "Going out of control" .)
