Drunk portrayed having dispensed with last of sherry in tumbler when maudlin? (8)
I believe the answer is:
teardrop
'tumbler when maudlin?' is the definition.
(something that tumbles when you're sad or maudlin)
I don't understand how the remainder of the clue works.
(Other definitions for teardrop that I've seen before include "Predator (anag.)" , "one running away from viewer" , "Globule of moisture indicating distress" , "It falls from the eye" , "Little sign of regret" .)
