Brandy glass; toy (7)
I believe the answer is:
balloon
This clue is a double definition.
'brandy glass' is the first definition.
(I've seen this before)
'toy' is the second definition.
(I know that balloon is a type of toy)
(Other definitions for balloon that I've seen before include "Inflate" , "One blown up for party" , "Swell, increase rapidly" , "Air transport" , "plaything" .)
