Drink in depression, upset by losing a lawsuit (6)
I believe the answer is:
tipple
'drink in' is the definition.
(thesaurus)
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for tipple that I've seen before include "Paint < pot" , "Drink alcohol regularly" , "Drink constantly in small quantities" , "Drink alcohol in small amounts" , "Habitually drink in small quantities" .)
