Circus artiste that can hold her drink? (7)
I believe the answer is:
tumbler
I believe this is a double definition.
'circus artiste' is the first definition.
(tumbling acrobat)
'that can hold her drink?' is the second definition.
(type of drinking glass)
(Other definitions for tumbler that I've seen before include "vessel" , "Drinking glass or old acrobat" , "spilling its contents?" , "Glass for whisky" , "slipper may become this" .)
