Furious mother and daughter (3)
I believe the answer is:
mad
'furious' is the definition.
(I've seen this before)
'mother and daughter' is the wordplay.
'mother' becomes 'ma' (Ma is another word for mother or mum).
'and' says to put letters next to each other.
'daughter' becomes 'd' (genealogical abbreviation).
'ma'+'d'='MAD'
(Other definitions for mad that I've seen before include "Roused to anger" , "Berserk" , "Extremely foolish" , "Crackers" , "like the March Hare" .)
