Mean to get sozzled (5)
I believe the answer is:
tight
I believe this clue is a double definition.
'mean' is the first definition.
('tight' can be a synonym of 'mean')
'sozzled' is the second definition.
('tight' can be a synonym of 'sozzled')
'to get' acts as a link.
(Other definitions for tight that I've seen before include "Firmly fastened; tense" , "Snug" , "Firmly fastened; drunk" , "Inebriated" , "lack of money" .)
