Drink good to be given to girl (5)
I believe the answer is:
glass
'drink' is the definition.
(I've seen this before)
'good to be given to girl' is the wordplay.
'good' becomes 'g' (abbreviation).
'to be given to' says to put letters next to each other.
'girl' becomes 'lass' (lass is a kind of girl**).
'g'+'lass'='GLASS'
(Other definitions for glass that I've seen before include "Tumbler, mirror" , "Perhaps schooner" , "Transparent substance" , "Brittle transparent material" , "Eg, tumbler" .)
