Woman in the bar getting drunk (6)
I believe the answer is:
bertha
'woman' is the definition.
'the bar getting drunk' is the wordplay.
'getting drunk' indicates an anagram.
'the'+'bar'='thebar'
'thebar' with letters rearranged gives 'BERTHA'.
'in' acts as a link.
(Other definitions for bertha that I've seen before include "Big - - , WW1 gun" , "collar" , "Girl's name - big German WWI gun" , "The bar (anag.)" , "Big ..., heavy German howitzer in World War 1" .)
