Some bar I drank dry! (4)
I believe the answer is:
arid
'dry' is the definition.
(similar in meaning)
'some bar i drank' is the wordplay.
'some' says the answer is hidden in the clue (some of the parts of the word are used).
'ARID' is hidden within 'bar i drank'.
(Other definitions for arid that I've seen before include "Desiccated" , "Drought-hit" , "Parched and barren" , "Dry and withered" , "Parched, waterless" .)
