Swung fish between daughters (7)
I believe the answer is:
dangled
'swung' is the definition.
('dangle' can be a synonym of 'swing')
'fish between daughters' is the wordplay.
'fish' becomes 'angle' (angling is a kind of fishing).
'between' is an insertion indicator.
'daughters' becomes 'dd' (I've seen this in other clues).
'angle' put inside 'dd' is 'DANGLED'.
(Other definitions for dangled that I've seen before include "Hung" , "was on gibbet?" , "suspended" .)
