A glass for the acrobat (7)
I believe the answer is:
tumbler
This clue is a double definition.
'a glass' is the first definition.
(I know that tumbler is a type of glass)
'acrobat' is the second definition.
(synonyms)
'for the' acts as a link.
(Other definitions for tumbler that I've seen before include "Type of drinking glass" , "Drinking glass or old acrobat" , "He performs feats" , "might be full of drink" , "A large glass" .)
