Many a man gets this woman's address (5)
I believe the answer is:
madam
'address' is the definition.
Although both the answer and definition are singular nouns, I cannot see how one could define the other.
'many a man gets this woman's' is the wordplay.
'many' becomes 'm'.
'a man' becomes 'm'.
'gets' means one lot of letters goes inside another (gets can mean captures or absorbs).
'this woman' becomes 'Ada'.
'm'+'m'='mm'
'mm' placed around 'ada' is 'MADAM'.
Can you help me to learn more?
(Other definitions for madam that I've seen before include "Stuck-up girl" , "Courteous form of address to a woman" , "Term of address to a woman" , "Formal address to a woman - precocious little girl" , "Conceited girl (colloq.)" .)
