Large glass for sherry (8)
I believe the answer is:
schooner
'large glass for sherry' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for schooner that I've seen before include "Item used for drinking" , "Measure for sherry or kind of sailing ship" , "No chores on this sailing ship" , "Type of glass" , "Sailing vessel - drinking vessel" .)
