Daughter gets sheep shot (4)
I believe the answer is:
dram
'shot' is the definition.
(of whisky say)
'daughter gets sheep' is the wordplay.
'daughter' becomes 'd' (genealogical abbreviation).
'gets' says to put letters next to each other.
'sheep' becomes 'ram' (male sheep).
'd'+'ram'='DRAM'
(Other definitions for dram that I've seen before include "Small drink (Scots)" , "Pick-me-up" , "Tot of whisky" , "Nip, snifter" , "Small drink of alcohol" .)
