Saw twin daughters embracing unmarried friend (5)
I believe the answer is:
dated
'saw' is the definition.
(to date someone is to see them romantically)
'twin daughters embracing unmarried friend' is the wordplay.
'twin daughters' means two replacements for 'daughters'.
'daughters' becomes 'd' (genealogical abbreviation for daughters).
'daughters' becomes 'd' (genealogical abbreviation for daughters).
'embracing' is an insertion indicator.
'unmarried friend' becomes 'ate' (I can't justify this - if you can you should give a lot more credence to this answer).
'd'+'d'='dd'
'dd' enclosing 'ate' is 'DATED'.
Can you help me to learn more?
(Other definitions for dated that I've seen before include "Walked out with" , "out of the ark" , "Passe" , "square" , "Archaic; took out" .)
