No daughter gives assent (3)
I believe the answer is:
nod
'assent' is the definition.
(I've seen this in another clue)
'no daughter' is the wordplay.
'daughter' becomes 'd' (genealogical abbreviation).
'no'+'d'='NOD'
'gives' is the link.
(Other definitions for nod that I've seen before include "Indicate assent or recognition" , "Doze" , "Signify consent" , "Where Cain went to" , "Acknowledge by gesture" .)
