Crossword Genius

Turn over, having united writer with daughter (5)

Ross

I believe the answer is:

upend

'turn over' is the definition.
(I've seen this before)

'united writer with daughter' is the wordplay.
'united' becomes 'u'.
'writer with' becomes 'pen' (I've seen this in other clues).
'daughter' becomes 'd'.
'u'+'pen'+'d'='UPEND'

'having' acts as a link.

(Other definitions for upend that I've seen before include "Set (something) vertical" , "Topple" , "Affect drastically" , "Knock over" , "Tip right over" .)

I've seen this clue in The Mirror.
