The name of a woman staggering in the bar (6)
I believe the answer is:
bertha
'the name' is the definition.
'a woman staggering in the bar' is the wordplay.
'the bar' can be anagrammed to 'BERTHA'.
Though, I am not sure how the anagram is indicated.
'of' is the link.
Can you help me to learn more?
(Other definitions for bertha that I've seen before include "Big ..., heavy German howitzer in World War 1" , "Breath (anag) - girl's name" , "Woman's name" , "collar" , "Big girl" .)
