Outburst from two females united in row on the way back (8)
I believe the answer is:
effusion
'outburst' is the definition.
('effusion' can be a synonym of 'outburst')
'two females united in row on the way back' is the subsidiary indication.
'two females' becomes 'ff'.
'united' becomes 'u'.
'in' indicates putting letters inside.
'row' becomes 'noise' (I've seen this in other clues**).
'on the way back' shows that the letters should be reversed in order.
'noise' backwards is 'esion'.
'ff'+'u'='ffu'
'ffu' placed into 'esion' is 'effusion'.
'from' is the link.
(Other definitions for effusion that I've seen before include "A pouring forth of thought or feeling" , "Outburst" , "Piece of unrestrained writing" , "Unrestrained outpouring" , "Gush" .)
